           Summary: d3dvideosink: start/stop concurrency between multiple
                    sinks

0004-d3dvideosink-start-stop-lock.patch

Concurrent start/stop actions on multiple d3dvideosink instances running in
parallel (distinct pipelines) may cause a crash. There is already a class mutex
that is properly used in d3d_class_init and d3d_class_destroy, but it is
momentarily released in both functions to let the window proc thread proceed.
This opens up a breach for simultaneous start and/or stop calls to conflict,
even on distinct sink instances.

Attached patch introduces another class mutex to serialize concurrent starts
and stops.
