• how to host live stream video

  21 août 2015, par Vhanjan

  Using jwplayer with html5 users can watch videos online..
  just put the source where the video file is located,, and the users can play the video that easy..

  i also tried to put a live stream source, as i remember it is rts ://sampledomain.com/video.mp4,
  then jwplayer easily play that mp4 file..

  my question is

  any hint are appreciated, but thank you very much for step by step tutorials..

• Record rtsp stream to a file to be played later

  16 avril 2021, par Саня Рыбалко

  everyone.
  
I have a UWP app, which can stream rtsp streams from online ip cameras by means of FFmpegInterop NuGet package. This is how I use the FFmpegInteropMSS object to set mediaElement's source to the rtsp stream :
  

  


          FFmpegInteropMSS ffmpeg = await FFmpegInterop.FFmpegInteropMSS.CreateFromUriAsync("rtsp://88.84.52.66/axis-media/media.amp");
        MediaStreamSource streamSource = ffmpeg.GetMediaStreamSource();
        mediaElement.SetMediaStreamSource(streamSource);
        mediaElement.Play();


  


  But I have run into a problem - I need to make it possible to record the stream in a local file to be played later. I have found out this is possible while using ffmpeg console, but I would prefer to use some c# tools(not only FFmpegInterop library) to do it.
  
Thanks for your help in advance.

  


• How to convert mp4 to mp3 in Android Java ?

  16 août 2023, par Akshit

  I have the mp4 link of a video but don't have a link for the mp3 version of that mp4 video. So is there any way that I can convert that mp4 video to mp3 in Android ? I saw some resources but nothing works for me. I have two ways in which I believe this can be achieved

  


  

  1. Convert the mp4 link to mp3 directly. (Not Sure if this is achievable)

  


  2. Download the mp4 on the device with the help of a link and then use some code to convert that mp4 to mp3.

  


  


  I also tried some solutions which are available online

  


  https://github.com/tanersener/mobile-ffmpeg

  


  I tried the above library to achieve the final goal. But got : Async command execution failed with returnCode=1.

  


  This error in the code I am using is :

  


  private class Mp4ToMp3ConverterTask extends AsyncTask {
    @Override
    protected String doInBackground(String... params) {
        String mp4FilePath = params[0];
        String mp3OutputPath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/output.mp3";

        String[] ffmpegCommand = {"-i", mp4FilePath, "-vn", "-ar", "44100", "-ac", "2", "-b:a", "192k", mp3OutputPath};


        Config.enableStatisticsCallback(new StatisticsCallback() {
            public void apply(Statistics newStatistics) {
                Log.d("Dekh", String.format("frame: %d, time: %d", newStatistics.getVideoFrameNumber(), newStatistics.getTime()));
            }
        });

        long executionIdd = FFmpeg.executeAsync(ffmpegCommand, new ExecuteCallback() {
            @Override
            public void apply(final long executionId, final int returnCode) {
                if (returnCode == RETURN_CODE_SUCCESS) {
                    Log.i("Dekh", "Async command execution completed successfully.");
                } else if (returnCode == RETURN_CODE_CANCEL) {
                    Log.i("Dekh", "Async command execution cancelled by user.");
                } else {
                    Log.i("Dekh", String.format("Async command execution failed with returnCode=%d.", returnCode));
                }
            }
        });

        FFmpeg.cancel(executionIdd);

        return mp3OutputPath;
    }
}


  


  Solution number 2 which I used is :

  


  https://androidprogrammatically425516919.wordpress.com/2020/04/21/how-to-convert-video-to-audio-in-android-programmatically/

  


  But I got an error here also : Failed to instantiate extractor.
  
And another error is : java.io.FileNotFoundException: open failed: EISDIR (Is a directory)

  


  I tried the online available solution to solve these errors but nothing worked. Such as granting write permission. Providing a valid location to save the output.

  


  But nothing works so far. Please help me on this. Thank you.
