10 months ago I have verified that the problem does not occur with the main branch because we reset Media Source when there are some errors. It seems like your content is muxed. Can you try not using muxed content with the same codec and see if it works? I would say that it is a limitation of the browser that with the main branch we are able to support. (HW vs SW codecs)

10 months ago Internally, it is also possible that there is a problem when we change the codec and container that transmuxer uses. the highest quality uses mp4 and the lowest qualities use ts. I'm going to look into this.

10 months ago I have found a bug in our logic that decides if we have to reset Media Source or call changeType.

I'll ask if we can get a non muxed one, but can't say how quickly we'll be able to test it, I will get back to you as soon as we tried it :D

10 months ago @avelad Just to clarify, am I correct in assuming that your fix only solves this issue when we use non-muxed content and that muxed content is not supported in this case? Because I tried it with the nightly-demo (assuming that the commit is already in there) and am now getting a different Error, but I suppose that is the wanted behavior?

10 months ago @Lubjan I just launched the job to update the nightly demo, in 15 minutes you will be able to test the fix in the nightly demo.
Note: the nightly demo only updates once a day by default, and therefore does not include this change yet.

What did you expect to happen? The player should load the non AV1 track normally.
What actually happened? Player doesn't load the track and fails with Error
CHUNK_DEMUXER_ERROR_APPEND_FAILED: Initialization segment misses expected aac track.I am aware that this is an 3016 error, but the tracks themself work fine, an other reproduction scenario:
At least to me, this would mean that there is no problem with the tracks themself, thus I'm reporting this error.
