What video format will play on all Android devices?

Question

Android can play a variety of video formats, but I need to choose one format that will work on all devices.

Do all Android 2.3 devices support exactly the same formats? i.e. if the format will play in the emulator, does that mean it will also play on all hardware? Or do different devices support different formats depending on what decoder chips they have?

If they are all the same then obviously the best format is H.264 at a high bitrate and resolution. If not, then what is the best codec/bitrate/resolution that will play on 90% of devices? Do Google provide some way of querying the device's video capabilities and choosing an appropriate format?

Answer 1

After testing on a lot of devices(for the video splashscreen of a very popular app). My recommendations are:

video codec : H.264  file format: .mp4 video bitrate: 256kbps video frame/second: 24 

Note:My video has no sound!!

But even with this recommendation, some videos will not work because of its resolution. So i create a tricky code: I embed all my videos for all the density in my raw folder, added an setOnErrorListener to my VideoView and i try to launch a smaller video each time an error occured.

This is my raw folder:

raw/    splashmdpi.mp4    splashhdpi.mp4    splashxhdpi.mp4 

and this is my java code:

int densityoffset = 0; VideoView video = new VideoView(this);  video.setOnPreparedListener(new OnPreparedListener() {              @Override                  public void onPrepared(MediaPlayer mp) {                     video.start();                     }  }  video.setOnErrorListener(new OnErrorListener() {             @Override             public boolean onError(MediaPlayer mp, int what, int extra) {                 densityoffset++;                 String suff = getDensitySuffix(getContext(), densityoffset);                 video.setVideoPath("android.resource://com.example.packagename/raw/splash"+suff);                 if(offset>5)                     return false;                 else                       return true;                 }             });  String suff = getDensitySuffix(this,offset); video.setVideoPath("android.resource://com.example.packagename/raw/splash"+suff);  private String suffix[]={"ldpi","mdpi","hdpi","xhdpi"};  /** *Return the suffix concerning your device less offset value **/ private String getDensitySuffix(Context ctx, int offset){         int dens = 2;         int d = getContext().getResources().getDisplayMetrics().densityDpi         if(d==DisplayMetrics.DENSITY_LOW)             dens = 0;         else             if(d==DisplayMetrics.DENSITY_MEDIUM)                 dens = 1;             else                 if(d==DisplayMetrics.DENSITY_HIGH))                     dens = 2;                 else                     if(d==DisplayMetrics.DENSITY_XHIGH))                         dens = 3;            return suffix[Math.max(0, dens-offset)];     }
