REGRESSION (271514@main): MSE Live playback fails on umediaserver.net
https://bugs.webkit.org/show_bug.cgi?id=266385
rdar://119615258
Reviewed by Jer Noble.
Changes in 271514@main exposed an underlying existing issue. The MediaSource's
duration was initialised to NaN
but the GPU process one was initialised to 0. Following 271514@main the inital
value would be identical.
If the media source duration was set prior any sourcebuffer being created, we
wouldn't set the SourceBuffer
initial duration, and the step `If the media segment contains data beyond the
current duration, then run the duration change algorithm with new duration set
to the maximum of the current duration and the [[group end timestamp]].`
would always be skipped.
We set the initial duration to the sourceBuffer when created.
Add tests.
