Description

When using <mux-video> in conjunction with Media Chrome, since version v0.16.5, when you try to play a HLS (.m3u8) video in macOS/iOS Safari, it treats it as mediastreamtype="live" on the Media Chrome <media-controller>. This causes the video to start from the beginning on every play/pause, and other weird behavior:

CleanShot.2024-05-02.at.18.52.02.mp4

versions <0.16.5 (0.16.4) and non-hsl streams work fine

Thanks @jakubslambor for the code sandbox, that's very helpful.

I noticed with <mux-video> you're using the src="https://test-streams.mux.dev/x36xhzz/x36xhzz.m3u8" ...

Although that should work, the API for using <mux-video> is with videos hosted by Mux Video, and you initialize it with playback-id for example <mux-video playback-id="fujsyrk0014ec2lpnm11bzc2maysaqpqa"></mux-video>. Setting arbitrary src= is not something we test or guarantee support for with <mux-video>.

(Incidentally, the URL you used is hosted by mux.dev, but that's a test stream that we happen to host for Hls.js demo purposes, and it isn't hosted by our "normal" Mux Video hosting product.)

This is still probably a bug that we should look into, but to get unblocked I think you have 2 options here:

1. If your video is a Mux Asset, use <mux-video playback-id="{PLAYBACK_ID}">
2. If your video is not a Mux Asset use <video> or use <hls-video>: https://github.com/muxinc/hls-video-element

Would either of those be possible for you to try?

@dylanjha Oh cool, I didn't know about hls-video-element, I'll give that a shot! Thanks 🙏

Keeping open (This is still probably a bug that we should look into), proceed at your discretion

Hi @jakubslambor, could you check if you still see the issue in the latest mux-video version?

I just tested on my end with v0.29.2 and it worked fine

I will go ahead and close this issue, but feel free to reopen if you have any news!
