* libavcodec/qsvenc: Add more pixel format support to qsvencWenbin Chen2022-04-06
| | | | | | | | | Qsv encoder only support input P010 and nv12 format directly from system memory. For other format, we need to upload frame to device memory and input qsv format to encoder. Now add other system memory format support to qsv encoder. Signed-off-by: Wenbin Chen <wenbin.chen@intel.com>
* 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/codec_internal: Rename AVCodecDefault->FFCodecDefaultAndreas Rheinhardt2022-03-21
| | | | | | | This structure is no longer declared in a public header, so using an FF-prefix is more appropriate. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* 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>
* libavcodec/qsvenc_hevc: encode RGB format rawvideoWenbin Chen2022-02-22
| | | | | | | | | | | Add support for hevc_qsv to input RGB format frame. It will transform frame to yuv inside MediaSDK instead of using auto scale. Now hevc_qsv supports directly encoding BGRA and X2RGB10 format. The X2RGB10 correspond to the A2RGB20 format and BGRA correspond to RGB4 format in MediaSDK.

* lavc/qsvenc: add Tiles encode support for HEVCLinjie Fu2019-12-12
| | | | | | | | | | | | | | | | | | | | | | Add -tile_rows and -tile_cols option to specify the number of tile rows and columns for ICL+ (gen 11) platform. A tile must wholly contain all the slices within it. Slices cannot cross tile boundaries. So the slice number would be implicitly resized to the max(nSlice, nTile). Example: ffmpeg -v verbose -hwaccel qsv -init_hw_device qsv=hw -filter_hw_device hw -f rawvideo -s:v 1920x1080 -i ./input.nv12 -vf format=nv12,hwupload=extra_hw_frames=64 -c:v hevc_qsv -tile_rows 2 -tile_cols 2 -slices 4 -y output.h265 Also dump the actual quantity of encoded tiled rows and columns in run time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | GPB is the default type, just contains forward references but the slice_type is B slice with higher encoding efficiency than regular P slice, but lower performance.

* lavc/qsv_hevc: correct QSV HEVC default plugin on WindowsZhong Li2018-12-18
| | | | | | | | | | | | | | | | | | | | | | | | | | 1. Old logic meaned: everywhere, except Windows, ffmpeg has to use HW acceleration, but on Windows ffmpeg has to use (unavailable) software HEVC by default 2. Software HEVC is available only if you provide corresponding software MediaSDK library, which isn't provided with ffmpeg. More information could be found in https://github.com/Intel-Media-SDK/MediaSDK/blob/master/doc/samples/readme-encode_linux.pdf 3. HW HEVC decoding/encoding are available on Windows in the driver by default Note: Default case should be the most common case but this change still has potential risk on windows if HW path is not supported(or doesn't work as expection). (See the historical disscution: https://lists.libav.org/pipermail/libav-devel/2016-November/080419.html). In such case, two options suggested: 1. Use the option "-load_plugin hevc_sw" to switch SW path manually. 2. Or report bug to Intel windows driver if your GPU can support HEVC HW codec. (HEVC decoding is supported since Braswell, and encoding supported since Skylake) Patch started by Landgraph. Add similar change for hevc decoder and bump a new version.

* avcodec: add metadata to identify wrappers and hardware decoderswm42017-12-14
| | | | | | | | | | | | | | | | | | | | | Explicitly identify decoder/encoder wrappers with a common name. This saves API users from guessing by the name suffix. For example, they don't have to guess that "h264_qsv" is the h264 QSV implementation, and instead they can just check the AVCodec .codec and .wrapper_name fields. Explicitly mark AVCodec entries that are hardware decoders or most likely hardware decoders with new AV_CODEC_CAPs. The purpose is allowing API users listing hardware decoders in a more generic way. The proposed AVCodecHWConfig does not provide this information fully, because it's concerned with decoder configuration, not information about the fact whether the hardware is used or not. AV_CODEC_CAP_HYBRID exists specifically for QSV, which can have software implementations in case the hardware is not capable. Based on a patch by Philip Langdale <philipl@overt.org>. Merges Libav commit 47687a2f8aca3f65b6fdd117b1cb66a7409a7fd1.
