* avcodec/thread: Don't use ThreadFrame when unnecessaryAndreas Rheinhardt2022-02-09
| | | | | | | | | | | | | | | | | | | | | | | The majority of frame-threaded decoders (mainly the intra-only) need exactly one part of ThreadFrame: The AVFrame. They don't need the owners nor the progress, yet they had to use it because ff_thread_(get|release)_buffer() requires it. This commit changes this and makes these functions work with ordinary AVFrames; the decoders that need the extra fields for progress use ff_thread_(get|release)_ext_buffer() which work exactly as ff_thread_(get|release)_buffer() used to do. This also avoids some unnecessary allocations of progress AVBuffers, namely for H.264 and HEVC film grain frames: These frames are not used for synchronization and therefore don't need a ThreadFrame. Also move the ThreadFrame structure as well as ff_thread_ref_frame() to threadframe.h, the header for frame-threaded decoders with inter-frame dependencies.

* 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.

* lavc/hevcdec: Parse DOVI RPU NALsNiklas Haas2022-01-04
| | | | | | | | | | | | | | | | And expose the parsed values as frame side data. Update FATE results to match. It's worth documenting that this relies on the dovi configuration record being present on the first AVPacket fed to the decoder, which in practice is the case if if the API user has called something like av_format_inject_global_side_data, which is unfortunately not the default. This commit is not the time and place to change that behavior, though. Signed-off-by: Niklas Haas <git@haasn.dev> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/h2645: Fix SEI->display matrix transformationAndreas Rheinhardt2021-12-23
| | | | | | | | | | | The earlier code did not account for the fact that av_display_rotation_set() wants the angle in the anticlockwise direction (despite what its documentation stated for a long time); furthermore, the H.2645 spec wants the flips applied first, whereas our code did it the other way around. This can be fixed by negating the angle once for every flip. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/hevcdec: apply H.274 film grainNiklas Haas2021-10-15
| | | | | | | | | | | | | | | | Similar in spirit and design to 66845cffc3bbb, but slightly simpler due to the lack of interlaced frames in HEVC. See that commit for more details. For the seed value, since no specification for this appears to exist, I semi-arbitrarily decided to base it off the POC id alone, since there's no analog of the idr_pic_id in HEVC's I-frames. This design is stable across remuxes and seeks, but changes for adjacent frames with a period that's typically long enough not to be noticeable, which makes it satisfy all of the requirements that a film grain seed should have. Tested with and without threading, using a patch to insert film grain metadata artificially (for lack of real files containing film grain).

| | | | | | | | | | | | | | | | | | | dereferencing it Since the decoder is not flagged as init cleanup capable, hevc_decode_free() is being called manually if the hevc_decode_extradata() call fails at the end of hevc_decode_init(). In a frame threading scenario, however, if AVCodec->init() returns an error, ff_frame_thread_free() will be called regardless of the above flag being set or not, resulting in hevc_decode_free() being called a second time for the same context. Workaround this by ensuring pointers are not dereferenced if they are NULL, and set the decoder as init cleanup capable while at it. Fixes ticket #9099. Signed-off-by: James Almer <jamrial@gmail.com>

| | | | | | | | | | | | | | | | 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).

* lavc/h2645_parse: Don't automatically remove nuh_layer_id > 0 packetsAndriy Gelman2020-01-17
| | | | | | | | | | | | | | | | | | | HEVC standard supports multi-layer streams (ITU-T H.265 02/2018 Annex F). Each NAL unit belongs to a particular layer defined by nuh_layer_id in the header. Currently, all NAL units that do not belong to a base layer are automatically removed in ff_h2645_packet_split(). Some data may therefore be lost when future filters/decoders are designed to support multi-layer streams. A better approach is to forward nuh_layer_id > 0 packets and let blocks down the chain decide how to process them. The condition to remove packets has been moved to hevcdec and cbs.

| | | | | | | | | | | | | The latest generation video decoder on the Turing chips supports decoding HEVC 4:4:4. Supporting this is relatively straight-forward; we need to account for the different chroma format and pick the right output and sw formats at the right times. There was one bug which was the hard-coded assumption that the first chroma plane would be half-height; I fixed this to use the actual shift value on the plane. We also need to pass the SPS and PPS range extension flags.
