[FFmpeg-devel] [PATCH] pthread_frame: uninit the hwaccel of each frame thread

[Lynne]

The issue is that with a threadsafe hwaccel and multiple enabled
frame threads, hwaccel->uninit() is never called.
Previously, the function was guaranteed to never have any threads
with hwaccel contexts, so it never bothered to uninit it.

Patch attached.
