[Bug 26060] Media Source and Web Worker

https://www.w3.org/Bugs/Public/show_bug.cgi?id=26060

--- Comment #2 from Saran Tunyasuvunakool <saran@exaeone.com> ---
>From my understanding, the MediaSource object itself parses the byte stream in
order to extract coded frames from its container (BMFF etc.), which is what
actually gets appended to the buffer, i.e. the SourceBuffer only holds the
elementary media stream(s). It is this step that I thought may benefit from
offloading into a worker.

While the append operations are asynchronous, is it not the case that they are
still queued to be executed on the main UI thread?

Since I am not involved in implementing a UA I have no idea how much work is
involved in this "demuxing" stage relative to the overall append operation. If
it is negligible then perhaps indeed there is not much point in enabling Worker
support.
