--- Comment #3 from Robert Bryer <robert.bryer at bbc.co.uk> ---
I wanted to know why only our simulcast streams were failing but not VOD output, so after a while I found that rebasing the timestamps to 0 also fixes it:

This example works and it's using the sourceBuffer.timestampOffset property so that the buffered range here starts from 0, instead of starting at an epoch-time(1718792755.2 in the failing example).

I can start the buffer range at numbers as high as 100000 without a problem, but more seems to cause it to stutter; so this is possibly something caused by big timestamps?
