* avcodec/threadframe: Add ff_thread_(get|release)_ext_buffer()Andreas Rheinhardt2022-02-09
| | | | | | | | | These will be used by the codecs that need allocated progress and is in preparation for no longer using ThreadFrame by the codecs that don't. Reviewed-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* 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.

* avcodec/pthread_frame: Don't prematurily presume frame-threadingAndreas Rheinhardt2022-02-09
| | | | | | | | | | | Several of our decoders support both frame- as well as slice-threading; in case of the latter avctx->internal->thread_ctx points to a SliceThreadContext, not to a frame-thread PerThreadContext. So only treat avctx->internal->thread_ctx as the latter after having checked that frame-threading is active.

* avformat/hls: Implement support for using AVSEEK_FLAG_BACKWARD when seekingGustav Grusell2022-02-09
| | | | | | | | | Before, seeking in hls streams would always seek to the next keyframe after the given timestamp. With this fix, if seeking in videostream and AVSEEK_FLAG_BACKWARD is set, seeking will be to the first keyframe of the segment containing the given timestamp. This fixes #7485.

* avcodec/cbs_mpeg2: Simplify splitting fragmentAndreas Rheinhardt2022-02-08
| | | | | | | | | | | | | | | | | | | | | | avpriv_find_start_code() supports non-contiguous buffers by maintaining a state that allows to find start codes that span across multiple buffers; a consequence thereof is that avpriv_find_start_code() is given a zero-sized buffer, it does not modify this state, so that it appears as if a start code was found if the state contained a start code. This can e.g. happen with Sequence End units in MPEG-2 and to counter this, cbs_mpeg2_split_fragment() reset the state when it has already encountered the end of the fragment in order to add the last unit (if it is only of the form 00 00 01 xy) only once; it also used a flag to set whether this is the final unit. Yet this can be improved by simply resetting state unconditionally (thereby avoiding a branch); the flag can be removed by just checking whether we have a valid start code (of the next unit to add) at the end.

* lavu/tx: refactor assembly codelet definitionLynne2022-02-07
| | | | | | | | | | | This commit does some refactoring to make defining assembly codelets smaller, and fixes compiler redefinition warnings. It also allows for other assembly versions to reuse the same boilerplate code as x86. Finally, it also adds the out_of_place flag to all assembly codelets. This changes nothing, as out-of-place operation was assumed to be available anyway, but this makes it more explicit.
