Android FFMPEG java concat multiple files
17 juillet 2015, par Kim TI’m using a fork of the cordova-plugin-video-editor library :
https://github.com/jbavari/cordova-plugin-video-editor/pull/13
Which uses the android-ffmpeg-java library here :
https://github.com/guardianproject/android-ffmpeg-java
The out of box cordova plugin example works well to encode a single video using the following code :
File tempFile = File.createTempFile("ffmpeg", null, appContext.getCacheDir());
FfmpegController ffmpegController = new FfmpegController(appContext, tempFile);
TranscodeCallback tcCallback = new TranscodeCallback();
Clip clipIn = new Clip(videoSrcPath);
Clip clipOut = new Clip(outputFilePath);
clipOut.videoCodec = "libx264";
clipOut.videoFps = "24"; // tailor this to your needs
clipOut.videoBitrate = 512; // 512 kbps - tailor this to your needs
clipOut.audioChannels = 1;
clipOut.width = outputWidth;
clipOut.height = outputHeight;
clipOut.duration = videoDuration;
ffmpegController.processVideo(clipIn, clipOut, true, tcCallback);This calls the android-ffmpeg-java code here :
They have a multiple file concat test example here :
So I have modified the cordova plugin code to match the example :
ArrayList<clip> listVideos = new ArrayList<clip>();
Clip clip = new Clip();
clip.path = new File(videoSrcPath).getCanonicalPath();
ffmpegController.getInfo(clip);
clip.duration = 5;
listVideos.add(clip);
Clip clip2 = new Clip();
clip2.path = new File(videoSrcPath2).getCanonicalPath();
ffmpegController.getInfo(clip2);
clip2.duration = 5;
listVideos.add(clip2);
Clip clipOut = new Clip();
clipOut.path = new File(outputFilePath).getCanonicalPath();
ffmpegController.concatAndTrimFilesMP4Stream(listVideos, clipOut, false, false, new ShellUtils.ShellCallback() {
@Override
public void shellOut(String shellLine) {
System.out.println("fc>" + shellLine);
}
@Override
public void processComplete(int exitValue) {
if (exitValue < 0)
System.err.println("concat non-zero exit: " + exitValue);
}
});
</clip></clip>However when run I get the error :

Using ffmpeg to convert sound files for use in an android app
10 janvier 2012, par stefsshort : i'm trying to simply play a sound file converted with ffmpeg in my android app, but happen to have problems getting it to work.
long : we have an iphone app and an android app doing the same thing, and i have to port the feature playing a sound on an user interaction. i have the source file in the
aiffformat, and tried to convert it tomp3for android. but the app keeps crashing when it tries to load the fileAssetFileDescriptor fileDescriptor = context.getResources().openRawResourceFd(resid);
final MediaPlayer mp = new MediaPlayer();
mp.setDataSource(fileDescriptor.getFileDescriptor(), fileDescriptor.getStartOffset(), fileDescriptor.getLength());
fileDescriptor.close();
mp.prepare();more specifically,
mp.setDataSourcecrashes. some digging around led me to believe that something's wrong with the encoding. the sound file itself resides in res/raw.11-29 17:11:48.012: ERROR/SoundManager(15580): java.io.IOException: setDataSourceFD failed.: status=0x80000000
11-29 17:11:48.012: ERROR/SoundManager(15580): at android.media.MediaPlayer.setDataSource(Native Method)
...what i tried :
- using a different mp3 that's already used with the same code in a different place. this works.
- converted it to wav file. this didn't cause the app to crash, but it neither played a sound. that might be a different problem.
- converted it to ogg ; crashed
so, the the
ffmpegconversion parameters are as follows :$ ffmpeg -i click_24db.aif -f mp3 ~/foobar/wheel_click.mp3

i don't have the slightest clue regarding bitrates and so on, so could anybody please point me to the right combination of ffmpeg parameters to get a working mp3 for android ? i don't care if the resulting file would be mp3, ogg or 3gp or whatever.
