Description Alicia Boya García 2022-08-30 06:38:56 PDT

This patch is a combination of a follow-up of
https://github.com/WebKit/WebKit/pull/3746, and a fix for a race
condition I independently discovered before said PR was published.

Minor cleanups for pr/3746 are done, additional logging is added,
MediaPlayerPrivateGStreamer::m_abortableTaskQueue is renamed to
MediaPlayerPrivateGStreamer::m_sinkTaskQueue, comments are added, and
most importantly: the task queue is flushed when a GStreamer flush is
received. This fixes a race condition on MSE flushes.
