Android video crop using ffmpeg
12 août 2016, par Pramod PatelI am using https://github.com/WritingMinds/ffmpeg-android-java for cropping a video using this command :
execFFmpegCommand(" -i " + in + " -filter:v " + "crop=" + 240 + ":" + 120 + ":" + 100 + ":" + 100 + " -c:a copy " + out);where "in" is inputfile and "out" is outputfile.
I went through a lot of same questions and couldn’t find required solution for this. I also tried the following command which i found going through the search :
execFFmpegCommand(" -i " + in + " -filter:v " + "crop=" + 240 + ":" + 120 + ":" + 100 + ":" + 100 + " -c:a copy " + out);The main error that I’m getting here is : Output file #0 does not contain any stream
private void execFFmpegCommand(final String command) {
try {
ffmpeg.execute(new String[]{command}, new ExecuteBinaryResponseHandler() {
@Override
public void onFailure(String s) {
Log.d(TAG, "FAILED with output : " + s);
progressDialog.dismiss();
}
@Override
public void onSuccess(String s) {
Log.d(TAG, "SUCCESS with output : " + s);
}
@Override
public void onProgress(String s) {
Log.d(TAG, "Started command : ffmpeg " + command);
Log.d(TAG, "progress : " + s);
}
@Override
public void onStart() {
Log.d(TAG, "Started command : ffmpeg " + command);
progressDialog.show();
}
@Override
public void onFinish() {
Log.d(TAG, "Finished command : ffmpeg " + command);
progressDialog.dismiss();
}
});
} catch (FFmpegCommandAlreadyRunningException e) {
