• Flutter FFMPEG : Error setting profile baseline

  9 avril 2021, par Raj Dhakad

  Flutter-ffmpeg unable to set profile parameter. (I need to use profile so the rendered video can be played on WhatsApp).

  


  I am converting.bmp images into a mp4 video. Other I have tested other praramets and the work great it's only -profile:v which seems to have some problem.

  


  Everything works fine unless I use -profile:v baseline.

  


  void _runFFmpeg() async {
    var dir = await getApplicationDocumentsDirectory();
    var output = await getExternalStorageDirectory();
    String videoSize = '${ImageWidth}x$ImageSize';
    print("${ImageWidth}x$ImageSize");
    var arguments = [
      "-y", // replace output file if it already exists
      "-framerate", "30", // framrate
      "-video_size", videoSize,
      "-pixel_format", "yuv420p",
      "-i", "${output.path}/frame_%d.bmp",  
      "-profile:v", "baseline",
      "-level", "3.0",
      "${output.path}/test.mp4"
    ];
    
    _flutterFFmpeg
        .executeWithArguments(arguments)
        .then((rc) => print("FFmpeg process exited with rc $rc"));
 

    print("Done Rendering");
  }

• Dash.js not playing mpd files made with ffmpeg

  31 décembre 2022, par Macster

  I'm using ffmpeg to create chunks and manifest of a webm file which I want to live stream with Dash.js. Unfortunately Dash.js won't play the mpd file, no matter which way I create the chunks and manifest. However, the sample mpd URL from Dash.js is working.

  UPDATE

  


  Well, it seems like the problem in general was, that the mpd's wouldn't play from that /dash folder. So i took a look into the code and found a bad routing. Anyways, the mpd would't start with the given command I used, probably becasue it creates a dynamic manifest, like @Markus Schumann says. So I'm going with a new one which seems to be working for now, but not very well.

• ffmpeg x11grab to streamable format

  2 juin 2021, par Jintor

  2 FFMPEG process

  


  (1) generating a ffmpeg x11grab to a .mp4
(2) take the .mp4 and restream it simultaneously to multiple rtmp endpoints

  


  ISSUE the generated file in (1) have this error "moov atom not found"

  


  This is the command that generate (1) :

  


  ffmpeg -re -y -f x11grab -draw_mouse 0 -framerate 30 
-video_size $RESOLUTION -i :$DISPLAY_NUM -c:a aac -c:v libx264 
-movflags +faststart -preset ultrafast -crf 28 -refs 4 -qmin 4 
-pix_fmt yuv420p -filter:v fps=30 file.mp4


  


  in the (2) => when I try to ffmpeg -i file.mp4 output somewhere : I get "moov atom not found" so the (2) can't read or open (1).

  


  What I'm I missing

  


  in (1) -movflags +faststart doesn't seem to fix the issue

  


  ••••••• EDIT : more details on the context ••••••

  


  I'm using openvidu : webrtc with kurento and coturn.

  


  The record feature creates a .mp4 on the fly as the chat is going on.

  


  To start the recording, there is an API call i can make to my server and it automatically stops when all users leaves the chatroom OR do an other api call to stop. see composed video in this link https://docs.openvidu.io/en/2.17.0/advanced-features/recording/

  


  openvidu have also webhooks.

  


  My problem is not how to stop ffmpeg, but getting FFMPEG to encode while the mp4 or other is being generated "on the fly".

  


  There is 2 options :

  


  OPTION 1 : individual => 1 .webm per camare => this .webm ffmpeg can restream as hls or RTMP => it's working.

  


  OPTION 2 : ** but the issue is with "Composed" video => it's using ffmpeg to x11grab the session... but it's mp4 without moov ato, so ffmpeg don't do anything with this.

  


  see the composed.sh script here
https://github.com/OpenVidu/openvidu/blob/master/openvidu-server/docker/openvidu-recording/scripts/composed.sh

  


  ***************** EDIT 3 *************

  


  in the .sh this is the part that is creating the mp4

  


  ffmpeg -y -f alsa -i pulse -f x11grab -draw_mouse 0
-framerate $FRAMERATE -video_size $RESOLUTION -i :$DISPLAY_NUM
-c:a aac -c:v libx264 -preset ultrafast
-crf 28 -refs 4 -qmin 4 -pix_fmt yuv420p
-filter:v fps=$FRAMERATE "/recordings/$VIDEO_ID/$VIDEO_NAME.$VIDEO_FORMAT"

  


  How can I modify this to have better result example VP8 or VP9 with good quality .webm so that the ffpmeg second command(2) can encode it live...

  


  **** EDIT 4 ********

  


  I tried this it worked for 30 seconds and suddenly stopped
