  • 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

    No luck with answers from other questions. Stuck since last 24 hours. :(

    Any help will be great.

  • sdp : Add an option for sending RTCP packets to the source of the last packets

    13 août 2013, par Martin Storsjö
    sdp : Add an option for sending RTCP packets to the source of the last packets

    An SDP description normally only contains the target IP address
    
and port for the packets. This means that we don’t really have
    
any clue where to send the RTCP RR packets - previously they’re
    
sent to the destination IP written in the SDP (at the same port),
    
which rarely is the actual peer. And if the source for the packets
    
is on a different port than the destination, it’s never correct.
    

    With a new option, we can choose to send the packets to the
    
address that the latest packet on each socket arrived from.

    — -
    
Some may even argue that this should be the default - perhaps,
    
but I’d rather keep it optional at first. Additionally, I’m not
    
sure if sending RTCP RR directly back to the source is
    
desireable for e.g. multicast.
