    10 décembre 2010, par

    Pour un fonctionnement correct et optimal, plusieurs choses sont à prendre en considération.

  • FFmpeg : Continuously download X minutes video from livestream ?

    16 février 2017, par Dorin Pleava

    I want to download X minutes from a livestream continuously and overwrite the same file, meaning the file will always have the latest X minutes from the livestream.

    Is there a way without calling the following command over and over again in a batch file ? Something that runs continuously from FFMPEG ?

    -i http://iphone-streaming.ustream.tv/uhls/17074538/streams/live/iphone/playlist.m3u8 -t 60 -y -c:a copy MyVideo.mp4

  • Java merge ? mix ? 2 audio files(mp3) parallely and download it

    4 février 2024, par JoonSeo Yang

    is there any way to mix 2 audio files parallely and let user download it ?

    


    I was trying it by ffmpeg

    


    FFmpegBuilder builder = new FFmpegBuilder()
                .overrideOutputFiles(true)
                .setInput(audioInputPath1)
                .addInput(audioInputPath2)
                .addOutput(outputFilePath)
                .setFormat("mp3")
                .setAudioCodec("libmp3lame")
                .setAudioBitRate(256000)
                .done();

        executor.createJob(builder).run();


    


    but it doesnt work by codec problem, so i want to know if there any other way to reach my goal, or fix my ffmpeg code to make it work ?

    


  • download rtmp live stream video secondly

    15 juillet 2024, par Chenguang He

    I'm working on a java project to create a rtmp server and download the real-time flv video every second(need to download multiple recording frame secondly instead of download entire recording after live stream finished)
This is my logic, firstly listen to the rtmp channel to write video and audio into file

    


    if(msg instanceof VideoMessage vm){
byteArrayOutputStream = new ByteArrayOutputStream();
 byteArrayOutputStream.writeBytes(vm.getVideoData());
            File file = new File("tmp/video_" + i);
            FileOutputStream fos = new FileOutputStream(file);
            fos.write(byteArrayOutputStream.toByteArray());
            fos.close();

}


    


    Then decode to H264 to get playable flv file

    


    FFmpegFrameGrabber grabber = new FFmpegFrameGrabber(input);
grabber.setFormat("h264");
        grabber.start();
FFmpegFrameRecorder recorder = new FFmpegFrameRecorder(outputFilePath, grabber.getImageWidth(), grabber.getImageHeight());
recorder.start();
while ((frame = grabber.grab()) != null) {
            recorder.record(frame);
        }
grabber.stop();
        grabber.release();
        recorder.stop();
        recorder.release();
}


    


    But this login was failed. I met this issue when I implemented the ffmpeg

    


    data partitioning is not implemented. Update your FFmpeg version to the newest one from Git. If the problem still occurs, it means that your file has a feature which has not been implemented.


    


    Is there any other idea to solve this or other way to achieve the logic ? Thanks
