Turns out the issue was using a 2x2 video, switching to 16x16 solved the issues. Yet another stupid Webkit limitation.

wintercounter avatar Mar 18 '25 12:03 wintercounter

There's nothing hls.js could do to play the video. You can file an Feedback Assistant bug report, including why 2x2 video should play.

Is there a reason to play the 2x2 video? Would an acceptable solution be to drop the video from the HLS asset so that it is audio-only?

robwalch avatar Mar 20 '25 16:03 robwalch

The reason it is a 2x2 is because:

  • we have to use Cloudflare Streams and they don't support audio uploads, so we convert them to videos first
  • I'm creating a black 2x2 image on the fly in the same command using ffmpeg, turns out that's the minimum, 1x1 is failing.

I'm using audio-only mode on the client side (only in Vidstack, possibly it isn't instructing HLS.js to do the same), but due to CF I have no control over the manifest.

I understand there's nothing HLS.js can do about this, let's close the issue.

You could try replacing each Level url with the audio playlist url on manifest loaded or parsed. v1.6 recognizes variant and alt media playlists with the same url as audio-only renditions.
