* avcodec/avcodec: Add FFHWAccel, hide internals of AVHWAccelAndreas Rheinhardt2023-08-07
| | | | | | | | | This commit is the AVHWAccel analogue of commit 20f972701806be20a77f808db332d9489343bb78: It moves the private fields of AVHWAccel to a new struct FFHWAccel extending AVHWAccel in an internal header (namely hwaccel_internal.h).

* avcodec/decode: Extend ff_hwaccel_frame_priv_alloc()'s taskAndreas Rheinhardt2023-08-07
| | | | | | | | | | | | | | | | All usages of ff_hwaccel_frame_priv_alloc() have the same pattern: Check for whether a hwaccel is in use; check whether it needs private frame-specific data; allocate the AVBuffer and set it. This commit modifies ff_hwaccel_frame_priv_alloc() to perform this task on its own. (It also seems that the H.264 decoder did not perform proper cleanup in case the buffer could not be allocated. This has been changed.) Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* lavu/frame: deprecate AVFrame.pkt_{pos,size}Anton Khirnov2023-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | These fields are supposed to store information about the packet the frame was decoded from, specifically the byte offset it was stored at and its size. However, - the fields are highly ad-hoc - there is no strong reason why specifically those (and not any other) packet properties should have a dedicated field in AVFrame; unlike e.g. the timestamps, there is no fundamental link between coded packet offset/size and decoded frames - they only make sense for frames produced by decoding demuxed packets, and even then it is not always the case that the encoded data was stored in the file as a contiguous sequence of bytes (in order for pos to be well-defined) - pkt_pos was added without much explanation, apparently to allow passthrough of this information through lavfi in order to handle byte seeking in ffplay. That is now implemented using arbitrary user data passthrough in AVFrame.opaque_ref. - several filters use pkt_pos as a variable available to user-supplied expressions, but there seems to be no established motivation for using them. - pkt_size was added for use in ffprobe, but that too is now handled without using this field. Additonally, the values of this field produced by libavcodec are flawed, as described in the previous ffprobe conversion commit. In summary - these fields are ill-defined and insufficiently motivated, so deprecate them.

* avcodec/codec_internal: Use union for FFCodec decode/encode callbacksAndreas Rheinhardt2022-04-05
| | | | | | | | | | | This is possible, because every given FFCodec has to implement exactly one of these. Doing so decreases sizeof(FFCodec) and therefore decreases the size of the binary. Notice that in case of position-independent code the decrease is in .data.rel.ro, so that this translates to decreased memory consumption.

* avcodec/av1: only set the private context pix_fmt field if ↵James Almer2022-03-23
| | | | | | | | | | | | | | | | | get_pixel_format() succeeds Otherwise get_pixel_format() will not be called when parsing a subsequent Sequence Header in non hwaccel enabled scenarios, allowing frame parsing when it shouldn't. This prevents the scenario seqhdr -> frame_hdr/redundant_frame_hdr -> seqhdr -> redundant_frame_hdr from having the latter redundant frame header parsed as if it was a frame header by the decoder because the former was discarded. Since CBS did not discard it, the latter redundant frame header is output with a zeroed AV1RawFrameHeader struct, which can have undesired results, like division by zero with fields normally guaranteed to be anything else.

* avcodec/codec_internal: Add FFCodec, hide internal part of AVCodecAndreas Rheinhardt2022-03-21
| | | | | | | | | | | | | | | | Up until now, codec.h contains both public and private parts of AVCodec. This exposes the internals of AVCodec to users and leads them into the temptation of actually using them and forces us to forward-declare structures and types that users can't use at all. This commit changes this by adding a new structure FFCodec to codec_internal.h that extends AVCodec, i.e. contains the public AVCodec as first member; the private fields of AVCodec are moved to this structure, leaving codec.h clean.

* avcodec/internal: Move FF_CODEC_CAP_* to a new header codec_internal.hAndreas Rheinhardt2022-03-21
| | | | | | | | | | Also move FF_CODEC_TAGS_END as well as struct AVCodecDefault. This reduces the amount of files that have to include internal.h (which comes with quite a lot of indirect inclusions), as e.g. most encoders don't need it. It is furthemore in preparation for moving the private part of AVCodec out of the public codec.h. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* 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/nvdec: Add support for decoding monochrome av1Philip Langdale2020-12-06
| | | | | | | | | | | | | | The nvidia hardware explicitly supports decoding monochrome content, presumably for the AVIF alpha channel. Supporting this requires an adjustment in av1dec and explicit monochrome detection in nvdec. I'm not sure why the monochrome path in av1dec did what it did - it seems non-functional - YUV440P doesn't seem a logical pix_fmt for monochrome and conditioning on chroma sub-sampling doesn't make sense. So I changed it. I've tested 8bit content, but I haven't found a way to create a 10bit sample, so that path is untested for now.

It happens e.g. in the cbs-av1-av1-1-b8-02-allintra FATE-test; it has just been masked because the return value of ffmpeg (which indicates failure when using Valgrind or ASAN) is ignored when doing tests of type md5.
