Encoding FFMPEG to MPEG-DASH – or WebM with Keyframe Clusters – for MediaSource API

Question

I\'m currently sending a video stream to Chrome, to play via the MediaSource API.

As I understand it, MediaSource only supports MP4 files encoded with MPEG-DASH, or

Answer 1

Another user has had some luck with:

ffmpeg ... \
  -f mp4 \
  -reset_timestamps 1 \
  -movflags empty_moov+default_base_moof+frag_keyframe \
  -probesize 200000

Please see see galbarm's questions at:

Note: If you don't have keyframes on the input video, you may need to set:

-frag_duration 100000

... instead of +frag_keyframe.
