• crop, rearrange middle of video frame with ffmpeg

  14 juin 2021, par Gavriel

  I have a few hundred video files from a security camera. Let's say here's the full frame :

  



  +---------------------+-------------------------+
| 2018-10-10 03:02:12 |                         |
+---------------------+                         |
|                         +--------------+      |
|                         | IMPORTANT    |      |
|                         +--------------+      |
|                                               |
+-----------------------------------------------+


  



  I have 2 areas that I want to keep : the date and the inner box.
I know how to crop to either of them, for example :

  



  ffmpeg -i in.mp4 -filter:v "crop=1120:320:40:60" -c:a copy out.mpg


  



  However what I'd like to be able to do is to rearrange the frame to get this in the output :

  



  +---------------------+
| 2018-10-10 03:02:12 |
+------+--------------+
| X X X|  IMPORTANT   |
+------+--------------+


  



  (X X X would be just black, or if that's hard to do then it can be whatever part of the original video)
Any idea how can I do this ?

  


• Is RTMP the better approach for video chat application ?

  23 octobre 2016, par Mohammed Safiq

  I have a flash media server. I want to create a live video chat application in Android devices.

  I am currently using RTMP method to secure my application, but I am not sure whether RTMP is the right security mechanism to secure my application ? Can you please tell me the right approach to secure my video chat application ?

  Also I am using ffmpeg for streaming the video and audio. Any better streamer which is better than ffmpeg ?

• Add headers to mpegts.js request

  8 avril 2023, par Alex Dalen

  I'm very new in web technologies. I have a .ts video accessed by my api and for security reason I need to add 'x-access-token' to my request, but really do not how. Maybe you know ?

  


  play(){
  if (mpegts.getFeatureList().mseLivePlayback) {
    var videoElement = document.getElementById('video-js-node');
    var player = mpegts.createPlayer({
       type: 'm2ts',
       isLive: true,
       headers: {'x-access-token': localStorage.getItem('data')},
       url: `/my/api/${record}`,
     });
     player.attachMediaElement(videoElement);
     player.load();
     player.play();
  }
}
