T95Z Plus Performance Issues - General Questions and Answers

Hello,
I have purchased a second hand T95Z plus, but have been experiencing issues with FullHD videos playback. Everything that is above 7Mbps is lagging. Tried different players - VLC, PlayerXtreme, the integrated video player. Tried with Wifi as well as with ethernet connection. Every time I play a decent FullHD quality video, it starts lagging. Just to confirm, this is not only for streams, but for videos stored internally and on a network share.
Obviously the issue is not with the connectivity, but with the video playback. The box itself is advertised as "easily" able to stream 4K videos, so I am afraid that it might have some hardware issues as 1080p videos with >7Mbps bitrate is lagging.
There might be overheating or some other related issues, but I am fairly new to this, thus am seeking help from other people with more experience with this device. If there is someone that is able to help me narrow down the main cause of this, I would be really thankful.
Here are details:
Android 7.1.2
Build: T5ZPE1081
BTW, when I start some 4K UHD video in Youtube it is playing it just fine. So maybe the issue is with the encoding or the video players that I use? Cause the 4K Youtube video is showing bitrate between 15 and 30Mbps.

[Q] Problem with YouTube video playback

Hello,
Suddenly I have a problem with YouTube video playback. The videos start streaming ok, but the appear small (not fullscreen) and very low quality. It used to work fine. The locally recorded videos play nice even in 720p. The problem is with the streaming video player.
I installed the LagFix (which works miracles) at somepoint earlier. Do you think that this could cause this problem? Any one else has seen it? The device is a Samsung S.
Thanks,
Michael

Video 720p, wifi, streaming, sharing

Hello. By searching it I find topics 5 years old, I couldn't find any solution.
I can read my network shares through file browser. I can play any videos by using mobo player, vplayer or rockplayer. I have noticed that 720p videos are very heavy, they are not smooth when software decoding, but they are smooth enough when hardware decoding with rockplayer : there will be no audio though.
- I have videos 720p on my desktop pc (mkv)
- I have a working wifi network with sharing
- I have a desire hd with enough video players and file explorers
What I want to do:
Over wifi, stream the videos on the phone without having the need to save other files. I was able to reproduce the videos WITHOUT waiting the download on the phone (stream), but they weren't smooth.
I guess 720p is too heavy for the desire hd?
So the questions would actually be:
1 - is there a way to stream the videos from the desktop pc hard drive with a quality INFERIOR to 720p ? Like a 'bitrate downgrade' on the fly, similar to what you would do on youtube by choosing the resolution you want for the selected video.
2 - Second solution (I may sound funny but I am not too expert in these things): is there a way to use the phone as a remote screen, that means the phone DOESN'T process the video. All the work would be done by the PC cpu which can run 720p just fine. The phone would just be a video output over the wifi, making the video pretty much smooth. Of course with enough buffer to get the video ready to go to the phone. Just like you can use the phone as a wifi camera, maybe you can use it as a wifi screen ?
Desire HD root, s-off, rcmixhd rom (sense)
VLC direct fixed everything for me. Can browse the whole pc, stream 720p with lower bitrate (extremely smooth and still sharp picture for a 4.3 display).

[Q] Xoom/Android Tablet Video

Hey guise.
I was wondering if there was any video player on android that can handle most video types or scale down video its incapable of playing at full quality. The video compatibility is the biggest problem on my tablet, maybe other users as well.
Try MX Video.

[Q] Laggy when playing video 1080p with VP9 video format

Hi, Recently I've downloaded video 1080p from youtube but when playing it, the video laggy but the audio just playing properly fine...
I thought it because the decoder set to H/W, but when switched to S/W both video & audio become laggy, then try switched to H/W+ it become worse (doesn't support this kind video it says...).
When I see media info of video, it use VP9 format video.
Here is the video: www[dot]youtube[dot]com/watch?v=aE2GCa-_nyU
I've tried on 3 devices; Asus Zenfone 6, Samsung Galaxy Note 10.1, and LG G2, all of it have the same issues...
And tried on PC to check if the video has errors or something, but the video is playing perfectly fine.
Is it something like bugs so the video didn't play properly? Or android can't play video with format VP9 properly?
Because I've tried other video 1080p, it can be played properly.
Oh FYI, I've tried using few other video player, and none of its can play the video as good as MX Player. That's why I've been using MX Player as default video player.
Hope there will be improvement on the next update so the video VP9 1080p can be played properly
MX Player is the best
All 1080p videos are not same.
It may lag at various parameters like higher frame rate, bitrate, color depth,....etc.
For example if you consider a video 1080p @ 30fps inorder to display 1 sec of videos it needs to decode 30 frames. Where as in 1080p @ 60 fps it requires 60 frames to be decoded. So, It will require the double power. Like wise various encoding parameters matters in video playback.
Second, H/W uses your hardware's native decoder . If the codec is natively supported by your device, H/W decoder will be the best option.
In case of S/W decoder, it supports more video formats since it depends on the ffmpeg. But, decoding will be completely done one CPU. So, it needs very high cpu power. That's why it's more laggy.

VP9 isn't a widely supported format. That's likely why HW and HW+ don't work well with it; most devices don't have VP9 hardware acceleration.
SW rendering of a 1080p video is very demanding. Even on the most powerful devices, since there's no hardware acceleration, expect performance to be sub-par. Currently, devices on the market can only SW render 720p smoothly.
This being said, for SW mode, try Settings > Decoder > use speedup tricks. See if that helps a little bit on SW.
Ultimately, the best option is to reencode the video to something like H264/AVC mp4.
VP9 on KitKat+

Can you explain more where you're trying to playback the video? VP9 support is built in to Android from KitKat+ and should not have an issue playing back. Additionally, can you try playing back the video on Chrome on Android and see if there are still decode issues?
Thanks.

I see... So the point is the problem because most devices don't have VP9 hardware accelaration yet, especially for 1080p VP9...
Well... I've tried using SW speed up trick, it didn't much help...
Yeah...maybe the best option is to reencode the video to H264...or download 720p version..., cause the 720p VP9 can be played perfectly fine.
Still... I hope the MX Player developer team has plan to improve playback for 1080p VP9 video
Btw thanks for your answer bro

As I said before, I'm trying to play 1080p VP9 video (that I've downloaded from youtube using IDM on computer) on my Asus Zenfone 6, Samsung Galaxy Note 10.1, & LG G2 using MX Player.
But when I playing it, the video is laggy on all devices...
Surely you can streaming it using youtube app & chrome android and it plays well till the end cause the available quality option in those apps is up to 720p (the 1080p quality option is hidden on those apps so I can't select it to test if it plays well or not).

That would be something you would have to ask the ffmpeg team to do, since MX uses their codecs. Unless the MX dev has a magic trick up his sleeve, I don't think there's much else MX can do to further improve SW playback performance for a video that exceeds the CPU's capabilities...
Likewise, on a hardware acceleration, it's limited by the hardwaree put in place by the manufacturer... so this aspect would need a new device.
Hi, i bumping this thread because i encountered the issue on some youtube vids too, but it's mostly playing fine, i think that with a few updates it will be good my phone is getting hot fast though.. (oneplus one)
VP9 1440p https://www.youtube.com/watch?v=mNNfZuIA1GQ : fine
VP9 1080p with a lot of "motion" https://www.youtube.com/watch?v=KGyZY4HNumw a bit laggy
I think I have already answered.
Read the second post. Video encoding parameters matters.
If you can't play in H/W or H/W+ decoder, Don't expect the smooth playback on S/W. It fully depends on CPU. If is laggy then your processor is not powerful enough. Sometime enabling the speed up tricks may reduce the lagging.
One more thing, using CPU will drain your battery faster than H/W. When CPU runs it's maximum speed for long time it will emit more heat which may lead to issues.

Okay thank you. Then i hope new processors will have vp9 decoding h/w

The chance of that happening, I can't see to be high. The MPEG consortium probably pays a lot to lobby chipset makers to only support MPEG formats, such as H.264 and H.265.

Lolno, it's just that industry is not interested in VP9. Even if they don't have to pay royalties they still have to develop asics (and h/w engineers are saying that it's not h/w friendly) and include them into the chip. It still costs a lot.
And what is the point of supporting vp9? It's an ugly google toy that they're ready to abandon (say hello to vp10 in 2015).
Ah yes, ASICs. I don't think manufacturers would be very happy at making more dies for new ICs. They already aren't happy with being forced to support Hi10p in H.265.
Forced? I would be happy if they were forced, but, at least Qualcomm, have no plans whatsoever

Well, this sucks. Looks like we'll be waiting another generation... Where did you find that support chart?
Edit: We should move this discussion to the 10-bit thread. I'm going to quote you over there. http://forum.xda-developers.com/app...layer-10-bit-video-discussion-t2725241/page12
abput supporting vp9 1080p and undeleting files in mx player p higher andrpid version
first of all:
"Most probably you’re on Android marshmallow 6.0 API. If you’re trying to delete a video that is located on the external storage then its not possible due to some bug in the file system and mx player.
If you’re on the internal storage then MX player has only read only rights on the directory on which you’re currently on."
or just delete on your internal system file manager application.
Second answer about playng videos vp9
becayse you can't play vp9 if you download youtube videos with IDM (internet download manager)
because it is bull**** and its newer versions used idmmkvlib.01 codec.so when downloadimg it not only download andit convert into ist bull**** special format.so won't play withx pr others.try another downloader or manual download yt videos i recomend.

Snapdragon 439 and 60fps 1080p problem - is it supported?

Hello, i have Yoga Smart Tab 10.1 (YT-X705F) with Snapdragon 439 and i have a problem i have never seen before.
I just restored the tablet to factory settings. Logged in with my account, updated youtube app. When i open any video with youtube app and set the quality to 1080p60fps, it tries to change it and then it changes back to 480p and i dont see the 720p60fps and 1080p60fps options in youtube app anymore. When i close the video and start it again, i see them again. 720p60fps option does work.
I tried playing video in chrome and firefox youtube player, 1080p60fps works, but its very choppy and slow. I have been having a lot of weird bugs with 60fps videos. For example some videos hosted on my NAS stream OK using my plex app, but some only in plex webpage player, some none at all. I have various android and ios devices at home and havent see this problem ever before. All my media problems seems to be linked to missing/bad 60fps video support.
I have tried several 3rd party youtube apps with advanced settings (like yt vanced), but i cannot get the 1080p60fps to work properly. Same problem with VLC and other video players playing 60fps videos.
Thanks.
Well, so i will answer my question. Lenovo was able to confirm, that this device and chip really does not have 60fps support.
English Community-Lenovo Community
I checked this with our team and they were able to confirm that the Yoga Smart Tab appears not to support that video quality (60fps) feature when used on YouTube and other apps.
