Cutting whatsapp shared videos using FFMPEG
2 août 2015, par Bhuvnesh VarmaI am using hiteshsondhi88/ffmpeg-android library to time or cut videos.I have added below dependency.
compile 'com.github.hiteshsondhi88.libffmpeg:FFmpegAndroid:0.2.5'
I am using below command
execFFmpegCommand("-i " + path + " -ss " + startMs / 1000 + " -to " + endMs / 1000 + " -strict -2 -async 1 " + dest.getAbsolutePath());
to cut or trim videos.
private void execFFmpegCommand(final String command) {
try {
ffmpeg.execute(command, new ExecuteBinaryResponseHandler() {
@Override
public void onFailure(String s) {
Log.e("Preview", "FAILED with output : " + s);
}
@Override
public void onSuccess(String s) {
Log.e("Preview", "SUCCESS with output : " + s);
}
@Override
public void onProgress(String s) {
Log.e("Preview", "Started command : ffmpeg " + command);
Log.e("Preview", "progress : " + s);
}
@Override
public void onStart() {
Log.e("Preview", "Started command : ffmpeg " + command);
}
@Override
public void onFinish() {
Log.e("Preview", "Finished command : ffmpeg " + command);
}
});
} catch (FFmpegCommandAlreadyRunningException e) {
// do nothing for now
}
}Its working for most videos but for some videos its NOT working especially for videos that are shared from whatssapp.It gives below error..I am using
Environment.getExternalStoragePublicDirectory( Environment.DIRECTORY_MOVIES )
for storage of videos.FAILED with output : WARNING: linker: files/ffmpeg has text relocations. This is wasting memory and prevents security hardening. Please fix.

Fast video compression like Whatsapp
5 août 2015, par Douglas AnunciaçãoI need to speed up video compression in my Android app. I’m using FFMPEG and it takes 3 minutes to compress 80MB video. Does anyone knows a better solution ?
The command I’m using is :
/data/data/com.moymer/app_bin/ffmpeg -y -i /storage/emulated/0/DCIM/Camera/VID_20150803_164811363.mp4 -s 640x352 -r 25 -vcodec mpeg4 -ac 1 -preset ultrafast -strict -2 /storage/emulated/0/DCIM/Camera/compressed_video.mp4
