Static Compilation of FFmpeg with x264 support
17 février 2014, par b1izzardBased on the Tutorial, I tried to build the latest FFmpeg binary with x264 support for Command line execution using Android-ndk-r9c.
I had built the x264 using the below script :

Playing RTSP stream in Android
9 décembre 2014, par KamilI’m trying to play video stream on Android device. Unfortunatelly I still get the same problem with MediaPlayer/VideoView. I’m searching for a few days, but still haven’t found any working solution.
For test purposes I’m using MediaPlayer app from API Demos (API Demos/Media/MediaPlayer/Play Streaming Video).
Here is code snippet for playing streammMediaPlayer = new MediaPlayer();
mMediaPlayer.setDataSource(path);
mMediaPlayer.setDisplay(holder);
mMediaPlayer.prepare();
mMediaPlayer.setOnBufferingUpdateListener(this);
mMediaPlayer.setOnCompletionListener(this);
mMediaPlayer.setOnPreparedListener(this);
mMediaPlayer.setOnVideoSizeChangedListener(this);When I try to play stream I get this info from logcat
