* avcodec/error_resilience: Only keep what is needed from MECmpContextAndreas Rheinhardt2022-05-19
| | | | | | | | | ERContext currently has an embedded MECmpContext, despite only needing exactly one function from it. This is wasteful because MECmpContext is pretty large (135 pointers, 1080 B for eight byte pointers). So keep only what is needed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/error_resilience: Remove unused labelAndreas Rheinhardt2022-02-15

* lavc/mpeg*: drop the XvMC hwaccel codeAnton Khirnov2022-02-15
| | | | | XvMC was last relevant over 10 years ago, if ever. There is no reason to use it today.
* avcodec/thread: Move ff_thread_(await|report)_progress to new headerAndreas Rheinhardt2022-02-09
| | | | | | | | | | This is in preparation for further commits that will stop using ThreadFrame for frame-threaded codecs that don't use ff_thread_(await|report)_progress(); the API for those codecs having inter-frame depdendencies will live in threadframe.h.

| | | | | | | | | | | | | | Currently, it needs to be initialized by the ER caller (which is currently either a mpegvideo decoder or h264dec). However, since none of those decoders use MECmpContext for anything except ER, it makes more sense to handle it purely inside ER.
