• lavc : shedule old encoding/decoding API for removal

  lavc : shedule old encoding/decoding API for removal
  It has been deprecated for 4 years and certain new codecs do not work
  
  with it.
  Also include AVCodecContext.refcounted_frames, as it has no effect with
  
  the new API.

• Is there a way to have a live website as an video overlay on RTSP stream using ffmpeg ? [closed]

  29 janvier 2021, par user161284

  I'd need to have a live website on one corner of my RTSP video stream, which is then streamed to Youtube. I know I can do this with OBS, but the point is that nobody actually operates the computer, so I though I'd use ffmpeg.

  


  I know that ffmpeg can add images as an overlay, but in my case the need would be to use a live website as the overlay. Whether this would be accomplished with "plain" ffmpeg or some other piece of (already existing) software in-between does not matter.

  


  After reading the ffmpeg documentation and some earlier posts a few years ago, it unfortunately seems that there's no way to use html as an overlay with plain ffmpeg.

  


  Any suggestions to overcome this challenge ?
