• I am trying to use the ffmpeg.wasm to transcode videos since i dont have very powerful servers does it work for HLS or DASH

  22 février 2021, par James Murry

  my website allows users to upload videos but my servers cant handle the traffic and the budget is low. i heard about webassembly and i have been looking to see if i can transcode on client-side and then upload the hls files to my server.

  


  I cannot find any documentation about hls on ffmpeg.wasm is it even possible.

  


• Produce an adaptive multi-resolution mpeg-dash file from an input video file

  1er mars 2021, par Tariq Hasan

  I can produce different resolution mpeg-dash videos from running these commands separately and get one .mpd file for each of the resolutions :

  


  ffmpeg -i /path/to/input.mp4 -vf scale=1920:1080 /path/to/output.mpd
ffmpeg -i /path/to/input.mp4 -vf scale=1280:720 /path/to/output.mpd
ffmpeg -i /path/to/input.mp4 -vf scale=720:480 /path/to/output.mpd
ffmpeg -i /path/to/input.mp4 -vf scale=640:360 /path/to/output.mpd


  


  The question is, how do I get a single .mpd file that maps to all these different resolution videos which would be adaptive in resolution when streamed over the network ?
