[PATCH 0/4] MR6255: mfplat: Some mf/winegstreamer fixes around pausing/unpausing a media session

[Torge Matthies (＠tmatthies)]

Commit 1 prevents the media session from starting execution of an asynchronous operation while another asynchronous operation is still running. Without this, it was possible for invalid state transitions to happen, which could leave the session in an intermediary state (not stopped, started, paused, closed or shut down) indefinitely.

Commits 2, 3 and 4 are some more fixes around pausing and unpausing in mfplat.
