  This patch adds support for creating DASH manifests for WebM Live
  
  Streams. It also updates the documentation and adds a fate test to
  
  verify the behavior of the new muxer flag.

• Documented ffmpeg commands not recognized by ffmpeg

  2 avril 2020, par agconti

  I'm trying to use options like, ldash and http_opts, as the dash muxer docs describe but FFmpeg doesn't recognize them. I'm on the latest released version of ffmpeg, v4.2.2. I see the changes in the ffmpeg master branch but not in the v4.2 release branch. Does ffmpeg not recognize them because they haven't been released yet ?

  



  Here's the dash muxer docs for reference : https://ffmpeg.org/ffmpeg-all.html#dash-2

  



  Here's a minimal example command with uncut output :

• nginx-rtmp video stream seeking functionality

  26 décembre 2020, par Priyansh Singh

  I am trying to make a video streaming service by using nginx-rtmp for reading stream and sending a dash/hls streaming media
Used this link for live streaming media

  


  I used obs for sending the stream to nginx
But it is a live stream and user cant seek the stream

  


  so, is there a way so that users cana actually seek it
Or is there a better way to stream video using dash/hls
