2020-04-10pthread_frame: merge the functionality for normal decoder init and ↵Anton Khirnov
init_thread_copy The current design, where - proper init is called for the first per-thread context - first thread's private data is copied into private data for all the other threads - a "fixup" function is called for all the other threads to e.g. allocate dynamically allocated data is very fragile and hard to follow, so it is abandoned. Instead, the same init function is used to init each per-thread context. Where necessary, AVCodecInternal.is_copy can be used to differentiate between the first thread and the other ones (e.g. for decoding the extradata just once).
2020-04-10lavc: replace AVCodecInternal.allocate_progress with an internal capAnton Khirnov
This is a constant codec property, so a capability flag is more appropriate.

2014-08-22rv34: use ff_mpeg_update_thread_context only when decoder is fully initializedJanne Grunau
MpegEncContext based decoders are only fully initialized after the first ff_thread_get_buffer() call. The RV30/40 decoders may fail before a frame buffer was requested. ff_mpeg_update_thread_context() fails on half initialized MpegEncContexts. Since this can only happen before a the first frame was decoded there is no need to call ff_mpeg_update_thread_context(). Based on patches by John Stebbins and tested by John Stebbins.

2014-04-09mpegvideo: operate with pointers to AVFrames instead of whole structswm4
The most interesting parts are initialization in ff_MPV_common_init() and uninitialization in ff_MPV_common_end(). ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL checks for Picture.f, because these functions can be called on uninitialized or partially initialized Pictures. NULL pointer checks are added to ff_thread_release_buffer() stub function. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

Several decoders disable those anyway and they are not measurably faster on x86. They might be somewhat faster on other platforms due to missing emu edge SIMD, but the gain is not large enough (and those decoders relevant enough) to justify the added complexity.
