  • How to get a list of audio devices in dshow and save

    25 novembre 2016, par H S T

    I use avformat_open_input in ffmpeg to open the audio device, but the second argument to this function is the audio device name, and may not be the full name. So how do I get avformat_open_input (& pFmtCtx, "video = dummy", iformat, & options);
    List of audio device names listed ?Or directly use ffmpeg to open the default audio device ?Thanks.

  • What is wrong part in my Android code with ffmpeg ?

    6 janvier 2016, par Marko androshenko

    I want to get mixed video.(Image + Video)
    Total duration of original video is 180 sec. I want to put image to the front of video. So, I made some code in android studio.
    But I can not look any toast.
    What is wrong ? How to check the end of process ?

    ...
    path = "libray folder" ;
    ...

        private class ProcessVideo extends AsyncTask {
    
            @Override
    
            protected Void doInBackground(Void... params) {
    

    
                Process ffmpegProcess = null;
    

    
                try {
    
          // initialize command for process video
    
              // library is video process library.
    
                    String[] command ={path,"-i", input, "-r", "1", "-q:v", "2", "-f", "image", input};
    

    

    
                    ffmpegProcess = new ProcessBuilder(ffmpegCommand).redirectErrorStream(true).start();
    

    
                    OutputStream ffmpegOutStream = ffmpegProcess.getOutputStream();
    
                    BufferedReader reader = new BufferedReader(new InputStreamReader(ffmpegProcess.getInputStream()));
    

    
                    String line;
    

    
                    Log.v(THISTAG,"***Starting FFMPEG***");
    
                    while ((line = reader.readLine()) != null)
    
                    {
    
// in progress 
    
                        Log.v(THISTAG,"***"+line+"***");
    
                    }
    
// finish all process
    
                    Log.v(THISTAG,"***Ending FFMPEG***");
    
                    videoProcessFinishFlag = true;
    

    
                } catch (IOException e) {
    
                    e.printStackTrace();
    
                }
    

    
                if (ffmpegProcess != null) {
    
                    ffmpegProcess.destroy();
    
                }
    
                return null;
    
            }
    

    
            protected void onPostExecute(Void... result) {
    
// show result
    
               Toast toast = Toast.makeText(VideoEditorActivity.this, "Done Processing Video", Toast.LENGTH_LONG);
    
                toast.show();
    
            }
    
        }
