@avelad This seems to be unrelated. I tested custom content with livestreams from https://ottverse.com/free-hls-m3u8-test-urls/

For example:
Live Akamai m3u8
https://cph-p2p-msl.akamaized.net/hls/live/2000341/test/master.m3u8

Works in Chrome, but Edge gives error: "Failed to set the 'timestampOffset' property on 'SourceBuffer': The timestamp offset may not be set while the SourceBuffer's append state is 'PARSING_MEDIA_SEGMENT'."

@joeyparrish can you review it? Thanks!

I'm unable to reproduce the issue.

I'm using this link:

https://shaka-player-demo.appspot.com/demo/#audiolang=en-US;textlang=en-US;uilang=en-US;asset=https://cph-p2p-msl.akamaized.net/hls/live/2000341/test/master.m3u8;panel=CUSTOM%20CONTENT;build=uncompiled

On Edge 109.0.1518.78 on Linux.

@avelad just pointed out to me that this only reproduces on Windows, due to Edge+Windows having native support for TS streams. On Chrome or Linux, where they are unsupported, they get transmuxed to MP4 first.

Please try enabling the option mediaSource.forceTransmux for TS live streams and see if that helps:

player.configure('mediaSource.forceTransmux', true);

If so, we could consider changing the default in a future release.

@joeyparrish @avelad I can confirm that enabling forceTransmux resolves the issue.

In your comment, the key was wrong - it should be streaming.forceTransmux (not mediaSource).
