Android phones Record video in 3gp? Am i dreaming? - Android Software/Hacking General [Developers Only]

i wanted to ask what is the deal with 3gp video recording on desire hd and htc hd2 custom android rom... I can't understand why android phones record video in 3gp??? i have desire hd and hd2 both record in 3gp file type... Does this mean that all android phones record video in 3gp? Can i somehow make my phone record in mp4 or some other video format? And after this, i officially say that desire hd is my last phone with android until they make avi or mp4 recording... I am happy i have a windows phone...

3gp's are basicly mp4's with a diff audio codec. Just rename it to mp4 and you should be fine.

@king_slavcho: 3gp, avi and mp4 are just containers. Knowing the container tells you nothing about which video and audio formats are inside, all three of them can store several different formats.
@InfiniteRisen: It's not a given that audio will be different, as 3gp can also store AAC audio. And just renaming the filename is *not* the thing to do, as the containers are slightly different. It might work most of the time, but that's just by chance.

As someone who has programmed using the FFMPEG API--which is considered the standard in the media encoding world-- I can vouch for what this man says; The AVI, MP4, m4v, etc are just formats(or 'containers' if you will) that hold the encoded video information. 3gp is probably more ARM friendly though.

It is because Galaxy S can't playback audio with 6 channels , i did not try this my self but that is what others observed.
Yes, I think it's limited to 5.1 channel audio encoded videos.
Also, that 4608kbps audio rate is awfully high.
Try using rockplayer and see if it works.
Was having a hard time w a video, wouldn't work in act1 nor the stock video player, worked great on rockplayer
Free on android market
Keep in mind Rockplayer is purely software player , it will not take advantage of phones Hardware acceleration , it will not play high resolution with good bitrate without dropping frames like crazy.
It would be better just to recode audio track.
I was just curious, because this was the same file that I had on my SD card that was in my BB Bold, which was able to play it???

need player for mkv files

i have some videos that are in the mkv format. i tried using rock player, but the video looks laggy and there's a discrepancy between the video and audio. it seems that the audio is ahead of the video. or is there a way to increase the frame rate for this format. i've tried almost every player in the market that came up under mkv and nothing that works right. my avi files work great though
I've tried all different players that play mkv and they are all laggy and the video is pixulated. I think the gtab is just not capable of playing them. But don't be sad the glorious opacity wont play them either results are the same.

i've been using rebox.NET found here http://www.videohelp.com/tools/rebox.NET, it basically re-muxes and converts audio to mp4 format from mkv, i've only tried 720p video so far, plays fine in rock player
I was reading the other day that an andriod version of VLC is being worked on. Hopefully that will do us right.

is this something you do on the tablet or you need to do it on a comp first?
why can't someone take the video player that comes with the archos101 and port into the gtablet? archos101 plays .mkv and just about everything else and I think the .apk is easily obtainable through archos101. I am not sure if the video player is what makes .mkv's work or if there is some system codecs involved. I used to have the archos101 and it did play .mkv's nicely.
yo do the conversion on the pc first, doesn't take but a couple minutes
The Archos player is probably optimized to the hardware inside the Archos which is different from ours.

I think a couple people have looked at doing that without success. I know I love the player on my little Archos5. It plays very nice, and also has the built-in upnp capability.
MKV (Matroska) support is compiled into stagefright/opencore on the devices that support it (Along with AC3, DTS, etc). It isn't just build into the player app.
Remember that matroska is just a container. being able to parse video streams out of an MKV won't magically give the Tegra2 enough beef to render 5.1aac+h.264 High-profile 1080p, in fact with the Tegra2 userspace libs in their current state you'll be lucky to get 1080p Main profile and only sure of playing Baseline profile.
Look at the video you want to play if its already High profile 1080p it will _never_ play on a Tegra2 device.
Remux (not re-encode) the MKV into an MP4 container, it it still doesn't play nothing short of updates from nvidia will change that.
ArcMedia
I've been using arcMedia and it runs flawlessly. Here's the apk. runs directly from Astro file manager. Long press on the video file, open file using archmedia. check the default box and every video file opened by arcMedia directly.

[Q] Video Convert configurations

Guys I have HTC sensation,
Can any one tell me the configurations to convert the video to play on my phone..
like wise,
video size
bitrate
frame rate
aspect ratio
etc
video codec
I use imToo video converter..
I need HD video..
everytime i convert I see quality is gone worse..
Help././
Just use some more advanced media player, like MX Video Player. Streams mkv, mp4 and avi seamlessly over upnp - So ill guess it plays most others as well.
I'm using DicePlayer. It plays everything so far.
Either use MoboPlayer

Or convert your videos to be 960x540

[Q] Whats the best video format for a Flyer?

Hi all, I've got a Flyer 10.1 which has been upgraded to 3.2 Honeycomb. What is the best format to convert a movie to, is it MPEG or MP4? any help would be much appreciated!
Basically you are referring to the same format since .mpeg is MPEG-1 and .mp4 is MPEG-4. These are just different versions.
I think there isn't much of difference in which one you use.
Put any format, like mikpel said over me
But for watching the movies try to use the MX player... for the PRO version, just google it
If you get some lags on the video, switch to S/W and its gonna work better but just if the video gets lagy
There is a difference as an mp4 can be in various codecs such as h264 or xvid whereas a standard mpeg video cannot.
Most common mp4 formats use xvid or h264 video codec with mp3 or aac audio.
Flyer supports mp4 in h263, h264, divx and xvid codecs with mp3 aac or wma audio.
Best for quality yet smaller filesize is h264 video with aac audio but an xvid avi mp4 with mp3 audio can be played on pretty much any thing and is similar in quality though produces slightly larger filesizes.

Exporting the High-Res audio from videos?

Hi, im having the following issue when trying to share the videos i recorded with my HTC U11, hope there is some fix for this.
I recorded a video with High-Res and the only way to share this video is with .mkv format, but the video needs to be edited and when is imported to Premiere there is no audio, neither if i convert the video to mp4 with media encoder, also tried to convert with VLC but no success.
Is there anyway or option that i missing to either extract the audio and insert it on a mp4, or convert the entire video to mp4 with audio?
Thanks.
Try media converter by antvplayer.
