  • Android video crop using ffmpeg

    12 août 2016, par Pramod Patel

    I 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();
    

    
            }
    
        });

    15 août 2016, par sparks

    I am trying to stream a live video from raspberry pi & pi camera module to web browser.But the video doesn’t play.I am using Nginx-rtmp and ffmpeg to process the video. On the client side i use dash js player trying to play the video but no luck.I see the warning on the terminal

    [flv @ 0x2c3b950] Failed to update header with correct duration.
    [flv @ 0x2c3b950] Failed to update header with correct filesize.

    But i am not sure if this could be the issue. Anybody knows what might be wrong ?I don’t expect a straight answer but i am sure somebody can guide me in the right direction. Thank you in advance. Here is my set up
