I’m currently running into an issue where playback does not work on Firefox. An example of the stream I’m using is:

https://{SERVER}/_definst_/mp4:AudioTracks/Test.m4a/playlist.m3u8

I’m using Windows 10, and this works in every browser except for Firefox, which doesn’t work. Below is the codec information:

When I attempt to play in Firefox, I get a console error that says “Media resource blob could not be decoded, error: Error Code: NS\_ERROR\_DOM\_MEDIA\_MEDIASINK\_ERR (0x806e000b)”

Any help would be greatly appreciated.
