• exec RTMP stream to HLS nginx server not working

  26 février 2019, par Serg Port

  I’m trying to convert an RMTP stream to HLS using ffmpeg in an nginx server
  This is my basic nginx configuration.
  If use push rtmp ://localhost/show/ instead of exec is saving data, but exec it’s not doing nothing.
  I can see the stream with ffplay,
  error —> RTMP_ReadPacket, failed to read RTMP packet header
  rtmp ://localhost/live/key : Invalid data found when processing input
  To test it I’m using OBS and ffplay

  #user  root;
  
  worker_processes  auto;
  
  
  
  
  
  events {
  
      worker_connections  1024;
  
  }
  
  
  
  
  
  # RTMP configuration
  
  rtmp {
  
      server {
  
          listen 1935; # Listen on standard RTMP port
  
          chunk_size 4000; 
  
  
  
          # This application is to accept incoming stream
  
          application live {
  
              live on; # Allows live input
  
  
  
              # Once receive stream, transcode for adaptive streaming
  
              exec ffmpeg -i rtmp://localhost/$app/$name -async 1 -vsync -1 -c:v libx264 -c:a libvo_aacenc -b:v 256k -b:a 32k -vf "scale=480:trunc(ow/a/2)*2" -tune zerolatency -preset veryfast -crf 23 -f flv rtmp://localhost/show/$name_low 2>>/tmp/ffmpeg.error; 
  
          }
  
  
  
          # This application is for splitting the stream into HLS fragments
  
          application show {
  
              live on; # Allows live input from above
  
              hls on; # Enable HTTP Live Streaming
  
  
  
              hls_path /mnt/hls/;
  
  
  
              # Instruct clients to adjust resolution according to bandwidth
  
              hls_variant _low BANDWIDTH=288000; # Low bitrate, sub-SD resolution
  
          }

• PHP - How to track video conversion progress - Stop ffmpeg process in PHP web [closed]

  21 mai 2022, par Mursaleen Ahmad

  I am working on a PHP web project where multiple users will be able upload and convert their videos bitrate using ffmpeg. And if users go to watch page before full conversion then "Video is being processed" message should show up.
I am using jQuery with AJAX and a watch link generated to watch online.

  


  1) How can I find the process is still running and show "Video is being processed" message to the users ?

  


  2) How can I stop ffmpeg process ?

  


  3) How can I get conversion percentage (how much video is converted) from file (as multiple users are using the site so can't work on single file named output.txt) ?

  


• How to convert video file to audio file by using FFMPEG ?

  15 janvier 2020, par Aamir Naseer

  I’m making video to audio converter app but need help to convert video to audio using ffmpeg. I checked many answers and websites but their answers are not easy to understand and I’m confused with command that is used to convert. What is the proper command to convert video to audio and is I’m executing the command in right way ?

  public class VideoConvertActivity extends AppCompatActivity {
  
  
  
      private VideoView videoView;
  
      private Button convertButton;
  
      private String filePath;
  
      private FFmpeg ffmpeg;
  
  
  
  
  
      @Override
  
      protected void onCreate(Bundle savedInstanceState) {
  
          super.onCreate(savedInstanceState);
  
          setContentView(R.layout.activity_video_convert);
  
  
  
          videoView = findViewById(R.id.videoviewID);
  
          convertButton = findViewById(R.id.convertbuttonID);
  
  
  
          ffmpeg = FFmpeg.getInstance(VideoConvertActivity.this);
  
  
  
  // in variable video i'm getting the path of video path from previous activity through intent and that video will have to convert to audio file
  
          Intent extras = getIntent();
  
          final String video = extras.getStringExtra("video");
  
  
  
          videoView.setVideoPath(video);
  
          videoView.start();
  
  
  
          convertButton.setOnClickListener(new View.OnClickListener() {
  
              @Override
  
              public void onClick(View v) {
  
  
  
                  try {

                          fileNo++;
  
                          dest = new File(moviesDir, filePrefix + fileNo + fileExtn);
  
                      }
  
                      filePath = dest.getAbsolutePath();
  
  
  
                      // to execute "ffmpeg -version" command you just need to pass "-version"
  
                      String[] command = {"-y", "-i", video, "-vn", "-ar", "44100", "-ac", "2", "-b:a", "256k", "-f", "mp3", filePath};
