Another creation of mine.
This is a blank live wallpaper that allows you to set your own video as a live wallpaper animation!
Lots of codecs and formats are supported.
You need to have your own video (preferably in MPEG-1 or MPEG-2 or divx) and set it in the Live Wallpaper's preferences. You can also set an entire folder (and optionally all its subfolders) and the Live Wallpaper will choose between all videos inside (randomly or not, your choice).
If you don't have any videos to play with, try this one or this one or this one. Download them with your computer and transfer them on your Android device, or downoad with the Android device directly (a common download destination is /sdcard/download). Then select one of them with the Video Live Wallpaper. (BTW, these videos are all reencoded electric sheeps designed by cqfd93 of the electric sheep project. Original links to the sheeps: 22906|22706|22551)
The preferences of the Video Live Wallpaper include Help which should help you get started with making your video(s) as live-wallpaper-friendly as possible. A copy of the same help document can also be accessed from here if you want.

Frequently asked questions - FAQ
I've downloaded and installed it. How do I open it?
This is a live wallpaper, not an app, you can't open it in a traditional sense. That is why the market button is disabled and that is why there is no app icon.
Follow this procedure to set it as a live wallpaper:
go to your home screen
press the menu button on your device
select "Wallpaper"
select "Live Wallpapers" *
search and select for "Video Live Wallpaper"
select "Settings" to see the settings and select the video file to play back. Then select "Set wallpaper" to activate it
(* if you don't see "Live Wallpapers" option in the "Select wallpaper from" menu then your device probably doesn't support Live Wallpapers)
My video loads but it's very jerky/looses frames alot, and it makes the home screen app very slow. What to do?
Not every codec and format is the best choice for the Video Live Wallpaper. The maximum video resolution recommended is 854x480, the maximum FPS at that resolution is 20. You can go as high as 30, but then decrease the resolution. MPEG-1, MPEG-2, MJPEG and MPEG-4 are the best codecs to choose for, while x263 and x264 are two of the worst possible ones because they are complex. If you have your video in a .flv or .mp4 format, try converting them to .mpg or .avi. In any case, please read this page (also embedded in the live wallpaper's help) to learn which kinds of videos are good and which aren't.
Why is there no sound? Will sound ever be supported?
Sound will likely never be supported, because:
it's extremely hard (with some codecs even impossible) to sync live wallpaper video to its audio due to how live wallpapers are handled (they often have to pause, they are often killed or slowed down by android in order to make swiping look smoother, for example, etc.)
sound just doesn't belong in an app that would play it all the time (or at least all the time that you're on a home screen). Shorter non-spontanious sounds are fine in a live wallpaper, but a long-lasting sound that never stops just starts to annoy the user after a while. Imagine for example you're in a meeting/at your job/in class and you can't even check the time on your phone without interrupting the said event. Imagine someone calling you and you suddenly hear two sounds out of your phone. Imagine listening to mp3s and being in the home menu at the same time. Sound just shoudn't be a part of any live wallpaper.
Please enable Move to SD.
No. Live wallpapers shouln't be movable to the SD. To learn why, read the official developer guide by Google.
Why does this Live wallpaper require internet access?
It's to download and show ads. They appear in the Live wallpaper's settings.
I can't find this on the market. Where is it?
Try to access it on your device directly using this link. If your Market can't find it then you probably have a version of Android prior to 2.1 which doesn't support Live Wallpapers.
I've downloaded the APK but I don't know how to/can't install it. How do I do it?
Try this:
on the phone, go to Settings -> Applications -> check "Unknown sources" *
find yourself a file browser on the Market. ASTRO File Manager is a good choice
open your file browser app, search for the APK file on your SD card and launch it. The phone should offer you a dialog to install the live wallpaper (or to select the Package Installer)
later when installed, go to home screen, press the menu key, select Wallpaper -> Live Wallpapers, search for Video Live Wallpaper
(* if your phone doesn't show the "Unknown sources" option, your carrier has disabled it. You might want to try one of the APK sideloading applications instead, like this one (you need a PC))
I can't download the APK. My phone says "Cannot download. The content is not supported on this phone". What to do?
Try downloading the app from the market first. If you can't, then download the APK with your computer and transfer the APK to the phone's SD Card. Or download with your phone using a downloading app, like ByteTornado.
This LWP is very cool. Thanks! How can I contribute?
In a number of ways:
by contacting me if you have any issues, not mentioned in this FAQ
by saying thanks
by buying me a cup of coffee or a pizza
great job! trying this now
Awesome job, it does work with some mp4 videos too, just a thought, you can try adding zoom out and timed

Depends on the codec of the video. Mpeg1, mpeg2, mjpeg and divx are amongst the best, x264 (mp4) is not great because it's complex to decode. See help for details for the best codecs and resolutions/frame rates. Or just do the similar to the sample videos: 560x420 (4:3), 20 fps (can go up to 23.976), divx codec, 2500-3500 kbps.

A tough one, since the rendering is heavily optimized on the idea that the entire video doesn't have to be decoded.
What do you mean by timed?

Great app and premise, but imo doesn't really seem worth it since the quality of the video and fps have to be lowered so much. I'll go ahead and download this to see just how much the quality is degraded as I've got some great hidef videos I wouldn't mind having as wallpaper. Has this been an issue with anyone else?
I haven't had a problem with the fps of any of the 720p youtube vids I've downloaded, though 720p ends up looking pixellated. 270x360 looks better. Using http://www.youtube.com/watch?v=92jyNSaNmT4 and it looks pretty good.

No reason not to try and experiment. For example on my Nexus, a 1280x720 video in MPEG-1 format will play at about 15 FPS if I disable frame skipping.
If I wanted it faster, I could crop it down to 720x720, which would then be able to be played at 20 FPS.
If I cropped it down further to 432x720 (which is the same ratio as the phone's 480x800 display), it would easily play at 25 FPS which is enough for my eyes, but still in full display's resolution.
If you know how to use ffmpeg, then this command will crop and convert a 720p .mkv file down to 720x720 at 20 FPS .mpg:
Code:
ffmpeg -i "720-input.mkv" -an -vcodec mpeg1video -vb 8000k -vf "crop=280:0:720:720" -r 20 "720-output.mpg"
Or this command would crop it to 432x720 at 25 FPS:
Code:
ffmpeg -i "720-input.mkv" -an -vcodec mpeg1video -vb 8000k -vf "crop=424:0:432:720" -r 25 "720-output.mpg"

Wicket video!
Flv and Mp4, while they work, are not the best formats to use with VLW. Try to convert them to .avi (divx) or .mpg (MPEG-1) for even better results.
Find your own way to convert, or use the free ffmpeg tool in one of the following two ways:
Code:
ffmpeg -i "original.flv" -an -vcodec mpeg4 -vb 8000k "converted.avi"
ffmpeg -i "original.flv" -an -vcodec mpeg1video -vb 8000k "converted.mpg"
(bitrate is overrated at 8000k, but the quality will probably be very good)
Thanks for the info, I'll definately give it a try!
Would any one care to donate a little time to make a video tutorial on how to use this live wallpaper? How to select a file to play, how to select an entire folder, what options are there, what video sizes are bad, etc...
I would embed it in the main web page of the app (and of course thank the author):
http://android.ccpcreations.com/vlw/
best video specs
Hello pikipirs et all!
I donatated $10 bucks because I really like the idea of true video wallpaper on my N1 and hope that you continue to develop and improve the app!
One can find lots of great video loops on the net that can be used. Some of them look great (i.e. Wallpaper attachment). Others look poor quality (i.e fs21 attachment). And others stop all together sometimes.
So I guess what I would like is simple, step by step instructions on how to convert or optimize a video so that it looks great and runs smoothly. I've tried using MediaCoder for example to convert the videos that look bad to MPEG1 (which you indicated in the help section was the best format) but they still look bad. What is the best format? Size? Resolution? Frame-rate? So that it looks perfect and how can one convert a video to these specifications? Can any video, formatted correctly, look good?
Oh and another suggestion would be, instead of the app randomly picking videos and switching them all the time, what about the option to only switch it when you 'wake-up' the device so that it doesn't cut into another video while you are viewing it but continues to loop.
Thanks again for the great app. Like I said some vids I've found look great but still, it would be nice to know how to make any video look as good.

Be prepared for a long answer.
This is subjective, I guess. The video will show in as good a quality as it actually is. The VLW (video live wallpaper) always zooms into a video in such a way that it covers the entire height of the display, while its ratio is not changed. The video's width is then used as scrolling surface so it shifts when you swipe between home screens.
The first video you posted has a vertical resolution of 480. This resolution fits very well in the height of a small mobile display (whatever resolution it might be) so you don't see alot of pixels. In fact, 480 is the maximum vertical resolution that I recommend for VLW, as higher ones might start causing the animation to play slower/skip video frames.
The second video you posted has a vertical resolution of 220. This gets close to the lower bound of acceptible pixel density for your eyes. While this is good on your phone's battery (VLW doesn't have to struggle as much to decode the video), it's not good on you eyes, that is, you can see video pixels which spoils the experience. One idea that I would have for the second video is maybe to reencode it rotated by 90 degrees. This way its vertical resolution will become 400 (current width) which would be easier on the eyes. (hold back on the rotating/reencoding part a little longer, as I plan on adding an option to rotate videos in the VLW).
Videos may play slower or even stop if they are too large for the underpowered phone's processor to handle. If you've been using computers for the last 10 years, then you should remember the ones that struggled to even play divx files properly. Some computers (like netbooks) have problems playing back HD content even today. The same is true for your phone. While a common divx should be handled by VLW just fine, any HD content (720p or 1080p) is way to much to handle. I guess what I'm trying to say is, don't go overboard with the resolution and don't expect miracles from your phone's processor.

There is no easy way to describe how to convert videos, as it almost always depends on the original video itself. As I said, a video is as good as it actually is. Reencoding, converting and/or enlarging it digitally won't make it any nicer.
Format changing is reasonable when you are dealing with resolutions and sizes that become hard to handle by the phone. Imagine a video with 854x480 at 30 FPS (your usual 480p video on youtube, for example). VLW has to process 854*480*30=12,297,600 pixels each second if it wants to play the video in real time. If this video is in h264 (which 480p youtube videos with .mp4 extension are) then it's even worse because h264 codec is very complex, which makes the processing part even harder. That's why I recommend reencoding to a less complex format, like mpeg-1 or mpeg-4 (divx).
Best format globally in my opinion is divx (mpeg-4 .avi). It represents a good compromise between complexity and size for a given quality. If you want less complexity (=more battery live), go with videoCD format (mpeg-1 .mpg) which will require larger files for the same quality, but is easier to decode for VLW.
Also one other thing to note, .mpg files need a bit of time to reload. This makes them useless for looping animations as the animation appears to freeze when looping. This is true for a lot of other formats/codecs as well. Divx doesn't have that pause (well it does, but it's amost unnoticable).
Resolution/frame rate is another tough one. The easiest way of going about it is to calculate the processed pixels per second, as I did above for the youtube video example. You can find all the help on how to do this in the help section. If you get your videos from standard 16:9 or 4:3 sources, then a couple of good resolution/framerate combinations are described in the help section. I recommend 360p (640x360 for 16:9, 480x360 for 4:3 videos, both at 30 FPS) or 480p (854x480 for 16:9, 640x480 for 4:3 videos, both at 25 FPS) in divx format. Remember once again - the biggest factor in the appearent quality of a perfectly reencoded video, is its vertical resolution. be between 360 and 480 and you'll be fine. The second biggest factor is frame rate, hold that one between 30FPS for 360p and 25FPS for 480p.

So you suggest adding an option to keep looping the same (but randomly choosen) video, and switch to another video only when the live wallpaper unpauses? That's a good idea. To a todo list...
PS: Are you on a mac or on Windows? I might be able to make a couple of simple scripts that use FFmpeg to convert videos with common ratios to better sizes/formats.

Im going to try and make this short.
I realize this may not be the best place to ask but i know you guys are the best to ask.
What are the best 1) resolution 2) bit rate 3) quality settings for encoding video for the gtab that give you a nice picture and dont break the ram bank.
At 768x450 2000bits/sec My test movie is 1.3gb. At the native 1024x600 the file size hits in the 1.7gb neighborhood (nice looking but probably not feasible unless i am only going to put one or two movies on here at a time...would like to do 5 or 6)
I tried it at 512/300 (50% of the native resolution) and a bit rate of 800bps and did manage to get the file at around 500mbs but the quality was just sub par for my tastes (fuzzy VISIBLY jerky).
Rather than me testing for days and days..i was wondering what settings you guys had set on (and why).
Thanks!
Allen
Edit: The H.264mp4 format was causing artifacting that i couldnt fix at any setting..
Right now i am using .mp4 at 768x450 (or a 75% scale of the native resolution) and a bit rate of 1,500 with the sound set at DVD quality (which actually does help since i use blue tooth head phones). File size still just at 1gb (that maybe about the smallest i can do with the quality i like). Even at that setting...its still a tad jerky. What should i try? Lowering the resolution and upping the bit rate a tad more???
Still wanting to know if any of you guys have a magic setting for me!
The good news here is that i am not loading my up memory with mp3/songs (have an iphone for that) using pandora radio instead. Regular apps dont take up too much room so i figure i probably have around 10G to play with for video. (when vegan gets the SD card utilizatin fixed ill have another 8G on top of that).
Bump:
Still looking for settings suggestions.
I am using 720X480 @ 1,500kbs in MP4. This gets me ~1.2gb files. It is the actual resolution of a DVD, which is where my material is sourced. This lets the display device do the scaling, rather than the encoding process.

Duh that makes total sense!
Testing now.
Any ideas what the "video quality output settins are". 1 is best, 32 is worse. 26 is recommended.
I dont have much to go on. I see the recommended settings for an ipad are 1335 bit rate and a quality setting of 24.
UPdate: When i did a test run with higher settings i noticed the video would lag every three or four seconds. I concluded that the settings were too high for the hardware to handle. Likewise when i set them too low..it was jerky, and i concluded the bit rate was too low for smooth frame rates.
At 720x480 1500Bits (and a "quality setting of 24"). The lag is MUCH better, but it still lags about every 20 seconds or so (very briefly). I will test at 1400bits/26q and see what happens.
Jeeze! A lot of work.... its too bad someone hadnt already figured all this out and just given me the quick answer! lol
Thanks again for the answer!
You should be able to play 1080 with no lag?
Sent from my V9 using XDA App
You may want to grab a program called Mediainfo. This program analyzes the video file and tells you what profile was used, video and audio encoding stats. I was using this to make sure my source and output files were not using the "High" profile. I have some 1080 files re-encoded under the "Simple" profile and they look great with zero lag. I have re-encoded all my files with Handbrake and the all work without lag.

I saw roebeets post about using the ipad settings but that makes no sense. THE ipad has a different resoultion and a less powerful processor.
I am getting lag at 720x450 1500bits but not at 720x450 1400 bits. Very interesting.
Am I being unrealistic in my expectations WRT playback of video on the Transformer? (NB After some of the replies below, I've added this comment to emphasise my point - I am NOT talking about high-def video here [e.g. 720p], just normal PAL or NTSC video taken from standard DVDs.)
I've ripped some DVDs using Handbrake on my Mac, using the default High Profile settings. The resulting h.264 files play smoothly and nicely on the Mac.
However, on the Transformer, the playback is juddery.
These are standard-resolution DVD rips, from TV shows and movies.
I wouldn't have been surprised for HD content to be a bit dodgy, but I was surprised not to be able to play SD content smoothly.
Has anyone else got good video playback (i.e. do I have a dodgy tablet) or is the Transformer with its Tegra 2 really not up to playing full-screen SD video?
Don't use high profile. Search before you post - there is many threads about video issues of Tegra2 devices here and in Xoom forum.
Why do people keep doing this, you have a Google tablet, Google this.
The Tegra 2 has a strange limitation, it doesn't play high profile. Before you make the mistake everyone else does, high profile is not a measure of quality, its the measure of compression. The bit rate is the quality.
Put it on high profile go to advanced, turn off 8x8 transform and Weighted P Frames and Subpixel ME to 6, use MP4.
Don't bother with other peoples presets, just use Moboplayer and you will be good with this setup.
Thanks
OK, thanks to you both for sorting me out with this. I did (contrary to appearances) try to find a thread on this topic but failed. Clearly I must brush up on my searching skills.
What about YouTube playback? Even this works terrible on my transformer. It keeps droping how of frames with latest firmware update.

there will be an update for this, also the browser player works fine for me.
Settings that work
OK. After some testing with the first chapter of the Matrix DVD (because I have it to hand and it's got some nice pans and action to check the juddering against), I have found that the following settings in Handbrake give me acceptable performance on my Transformer with the h.264 codec. This is standard-definition video, please note, NOT high-def.
Note that sorting this out is far from as simple as "Google it" because there are a great many mutually contradictory sets of advice out there!
I took the Normal profile, then went to the Advanced tab and disabled CABAC and set the max B frames to 0.
This was the least dramatic setting that gave smooth playback on my Transformer. So I guess I should repeat my original question - given that my tablet appears to require much lower video settings than generally advised AFAICS in order to get smooth video playback (it's hard to measure this but this is my preception), should I worry? Or is this pretty much what everyone finds with the Transformer?
(The easiest way to get smooth video seems to be just to switch to the MPEG-4 codec and to increase the quality to about 3 to compensate. However, this gives files that are 40-50% larger, so I wanted to avoid that if possible.)
I usually use Handbrake for everything but I was in a hurry so I tried Freemake Video Converter. I converted a few downloaded x264 MMA videos. It has built in settings for Android. I was surprised how well it looked.
I'll still probably go back to Handbrake as soon as I have time to setup and test various suggested settings listed here and some other forums.

Are you using handbrake? If so, are you using constant quality, bitrate or target size for your encode?
The Tegra 2 supports 720p High Profile Hardware Decoding, but Honeycomb can't utilize it yet. 3.1 or something later should address this.

NOT about high-def content
Can I reiterate that my query is NOT about high-def content (e.g. 720p)? I'm talking here about being able to view simple SD content from a DVD I've bought, without juddering.
Can other folks view standard DVD rips on their Transformers using standard Handbrake settings, with no juddering during whole-screen update sections (e.g. pans or action sequences)?
I just used Adobe Media Encoder CS5 (part of the Creative Suite) to encode a file and it played flawlessly on my xformer. I used the Apple TV Preset as a base then modified the profile from main to baseline.

seshmaru:
Unless you know something is there then you don't know to search for it. Now I know, I have searched and found that what I posted above is basically the situation - no B frames, no CABAC.
That being said, all the discussion I have seen has been based on 720p content rather than standard def so it's not clear to a newcomer to video issues that tthe same restrictions necessarily apply.
Anyhow, that seems to be the answer so thanks to all for the help.
I have a Handbrake profile saved from back in March. I found it from a YouTube video links section, where the author of the "how-to" video about re-encoding video for the best playback on the Xoom posted a link to a pretty good Handbrake preset for the Xoom.
I am just wondering... if video playback is now better in Honeycomb 3.1, if there would be a better setting (for better quality video) out there? Does anyone have a Handbrake preset that looks really good on the Xoom that is new for the 3.1 update?
The preset I have from March works well, and videos encoded using the preset play without stutter - but the quality is a bit blurry at times... which leads me to wonder if the Xoom couldn't handle higher quality video now.
I had lots of trouble finding the right combo with Handbrake. Videos would play fine but weren't very crisp.
Switched over to the latest version of an old app - DVD Fab. Works extremely well, videos are sharp and play buttery smooth.
JFMFT,
What setting are you currently using? I'm at work so cant check mine right now. I know whatever settings I was using seemed to work pretty well-will get back to you with specifics.
If you have a solid preset to tweak, then try using the "Constant Quality" setting under the "Video" tab:
Constant Quality - Handbrake
CRF Guide - Handbrake
Read the above links; they have great info. If you don't, then at least note that higher RF means lower quality (higher compression).
For me, a single Handbrake preset doesn't produce the results I want -- good quality balanced with decent file sizes -- across different kinds of video. Animation differs greatly from fast-paced action (frames, distinct lines/edges, blur, etc.), for example.
In Handbrake, I started with H264 baseline profile settings, then settled on some tweaks in the "Advanced" tab after some reading and experimentation:
Motorola Support FAQ: Motorola XOOM - Optimal video settings
HandBrake Docs (links to option descriptions): x264 Options - Handbrake
Now, I vary only the "Constant Quality" parameter between RF 19 and 25, depending on the type and quality of the source. It takes some trial and error, but I think it's a worthwhile effort. Working first with short samples (5-10 min) from the video source will help things move quicker, too.
Get RockPlayer, it literally plays everything.
Forget Handbrake / DVD Fab. Free vs Cost issue aside, DVD Catalyst 4 FTW!
Away from home currently, but I will check into my settings & report back soon.

Hit the link above there is a section provided Handbrake info and a download link to a working preset file. =)

try this one?
Here are my Handbrake settings for my Xoom.
I'm getting pretty good results in term of quality/size.
For the Picture settings, I'm changing the Anamorphic to None and setting the Width to 1280 (be sure to check the Keep Aspect ratio).
Maybe the Anamorphic could be changed to other, I didn't test to see the difference.
You can try setting Constant Quality or increase the Bitrate value (I'm using 1500 which seems to be enough)
Encoding is quite fast (depending of the PC of course)
Enjoy playing them with the default HC video player

"video playback is now better in Honeycomb 3.1" i agree. Honeycomb 3.1 improve the hardware capabilities, so video will play more smoothly. but for video conversion, you need to increase the bit rate. this is my own experience.
I'm sure you noticed that when you record a 720p/1080p video with a smartphone, the bitrate will be pretty high, in the 10-15Mbps area.
This is not really necessary if you watch the videos just on your smartphone or on a limited size LCD TV, and you can just recompress it using x264 codec at about 2Mbps without severe quality loss (unless it's a sport video).
However you'll notice severe audio video out-of-sync issues if you compress both audio and video tracks and DON'T CHOOSE MP4 (which is the default container for the videos recorded by the smartphone) as default container for your x264 video.
Furthermore, if you want to compress and then JOIN different videos, you have to compress them one by one and THEN join them, otherwise you'll notice glitches in the playback.
I tried with mkv and avi but I kept having sync issues, so I thought that it was worth to share this tip.
SUPER @ video conversion program
Have you tried a video conversion program called SUPER @? Here's its link:
http://www.erightsoft.com/SUPER.html
The program can be pretty intensive in terms of memory used but it usually does a great job for me and bitrates can be chosen for just any vid type you might want to save to. Usually, I turn off my internet connection prior to executing it (so it can't do an update check) and run it by itself.
Yep, I guess it's something similar to Wondershare Video Converter Ultimate, it's just that I prefer more control over encoding parameters (so I tend to use programs such as Avidemux)

You've probably already thought of this but you can load your video in virtualdubmod and have it change framerate so video and audio match perfectly.
No re encoding needed and even on large files it takes less than a minute or two.
If you find virtualdubmod won't recognise the video you can download a suitable vfw codec and it should then.

The problem is that vdubmod won't help, because framerate is not constant and it varies from some 19 to 30fps, at least on Vibrant.
In a lot of cases the fps number gets lost during encoding (and you'll obtain a video which has a constant framerate of 29.97fps), because softwares such as Avidemux doesn't have an option to leave the FPS untouched (or at least it seems that the fps number gets lost if you want to use MKV as container).

I've used it in similar situations so it might be worth a try as it doesn't need a constant framerate, it looks at the audio length then adjusts video framerate to match.
If it is just a problem created while actually recording, ie if the video itself records at varying framerates it would suggest that it can't write to storage quick enough and is dropping frames.
In that case you would need to record in lower resolution or perhaps find a replacement camera application and see if that could fix your problem as sometimes default apps are not all that good.
It also makes a difference if you can close un needed background apps to free ram if low on memory. That can cause frames to drop as well.

Actually it seems that the framerate is lower in case of dark scenes, which seems to be a behaviour found on other phones. I'm writing on the internal storage and I always kill everything before taking a video, so I gotta try another Camera app and see if anything changes.
I'll also take a look at that interesting vdubmod feature, I didn't know it.
Thanks.

Is there a setting where you can change encoding parameters of your x264 on your phone?
On a pc the codec has a feature that can compress more data per frame in darker areas, on a phone I don't know if that is active or not but might be worth checking. Sorry I couldn't help more but hope you find a solution.

I don't know if the title is appropriate for this request.
I mean MX Player would be better with a button to capture a shot from a video.
Why need an internal capture when Android OS already has a capture feature?
Because capture in Android OS simply interprets what is shown on the screen and saves it and I think the interpretation process is unnecessary because the data is already included in the video file. (I don't know much about video encoding/decoding, so if im wrong sorry for my ignorance on the subject) The resulting image is poor in quality and most importantly takes up TOO much space. If I capture the same scene on the same video by video playing programs (KMP, etc), I get better capture image small in size also(as much as 20 times smaller).
Another problem with Android capture is that ads (I don't know the free version still shows ads when tje video is paused) or soft-keys (although it can be hidden by the app) can be captured together.
And finally, capture is done not considering the size of the video. Android merely captures the screen as shown, the captured image's resolution is the same to the device's screen's resolution, which is a problem when playing videos with higher or lower resolutions or when the video's height-width ratio is different to that of the device's screen(4:3, 16:10, CinemaScope, etc).
So, I think it would be wonderful if you would consider including an internal capture feature in the app.
I think you're working on Frame-by-Frame feature, so I guess it can be related to that.(again, sorry if Im wrong)
Im always happily using MX Player for years and I appereciate your efforts. :laugh:

From your description it looks like you looking for trimming feature. There are many apps are available in Google Play which can trim the video without recoding. It will do the job as you are expecting.

Yes, I'm aware that there are lots of video trimming/frame break and capturing/editing apps available. But I was just thinking that it would be nicer to have a capturing (I believe it is different from trimming, since capturing is about extracting just one frame out of the video while trimming is extracting multiple continued frames and merging it) feature included in the MX Player so that I can easily watch a video and capture "a" frame without opening another app while watching a video. It is not a big and urgently needed feature, but it would make things more easier.

It's my mistake. Apologizes for that. I have misunderstood the word Capture.
Anyway I will convey your request about frame extraction/capture feature to the developer.
