    15 mai 2021, par samoel

    I'm trying to get a .mp4 file from an address and remove the sound from it.I also want the data sent to FFMPEG to be bytes and return the result in byte

    


    i tried different command for my code like using -movflags frag_keyframe+empty_moov.
When I run this code in Heroku and receive the log...

  • Revision 2fa9e9e227 : Fix the frame parallel invalid file test failure on ARM. There is a corner case

    9 février 2015, par hkuang

    Changed Paths :
     Modify /test/vp9_frame_parallel_test.cc


     Modify /vp9/vp9_dx_iface.c



    Fix the frame parallel invalid file test failure on ARM.

    There is a corner case that when a frame is corrupted, the following
    inter frame decode worker will miss the previous failure. To solve
    this problem, a need_resync flag needs to be added to master thread
    to keep control of that.

  • JavaCV generate video from images Crashes

    2 décembre 2014, par Mohammad Khatri

    I am doing javacv with android since yesterday and getting error while generating video from image (IplImage) using FFmpegFrameRecorder or FrameRecorder while getting succes in imagefiltering using cvCvtColor and cvCvtColor.

    grayscale

    As shown in picture , Grayscale and flip filter is done by clicking second Button (Apply Effect).

    But when clicking (Make Video) it crashes.

    Here is my code for making video from image.

    String path = Environment.getExternalStorageDirectory().getPath() + "/test.mp4";
    
Log.i("path", path);
    
FFmpegFrameRecorder recorder = new FFmpegFrameRecorder(path, 256, 256);
    
try {
    

    
    recorder.setVideoCodec(avcodec.AV_CODEC_ID_MPEG4);
    
    // recorder.setCodecID(avcodec.AV_CODEC_ID_H263);
    
    recorder.setFormat("mp4");
    
    recorder.setPixelFormat(avutil.AV_PIX_FMT_YUV420P);
    
    recorder.start();
    
    for (int i = 0; i < 10; i++) {
    

    
        recorder.record(image);
    
    }
    
    recorder.stop();
    
} catch (Exception e) {
    

    
    e.printStackTrace();
    
}

    image is of type IplImage

    getting error on recorder object creation.

    I am using 2 devices

    1)Asus zenfone 5
