* lavc: Mark hw_config pointer arrays as constMark Thompson2020-11-08
| | | | They are read-only just like the HWConfig structures they point to.
* lavc/qsvenc: Add hardware config metadataMark Thompson2020-04-26
| | | | | | All of these encoders can accept libmfx surfaces directly in a hardware frames context, or they can accept software frames if a suitable device is supplied to use.
* 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.

* lavc/qsvenc: enable vp9 encoderZhong Li2019-11-03
| | | | | | | | | | 1. must enable low_power mode since just VDENC can be supported by iHD driver right now 2. Coding option1 and extra_data are not supported by MSDK 3. IVF header will be inserted in MSDK by default, but it is not needed for FFmpeg, so disable it. Signed-off-by: Zhong Li <zhongli_dev@126.com>
* lavc/qsv: Fix MSDK initialization failure in system memory modeZhong Li2019-09-26
| | | | | | | | | | | | MSDK does not create internal acceleration device on Linux, So MFXVideoCORE_SetHandle() is necessary. It has been added for ff_qsv_init_session_device(). But missed for ff_qsv_init_internal_session() due to commit 1f26a23 overwrited commit db89f45 Fix #7030 Signed-off-by: Zhong Li <zhong.li@intel.com>
* lavc/qsvenc: enable hevc gpb optionZhong Li2019-04-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Add an option to allow user to set regular P slice. Fix ticket#6870 Test data on Intel Kabylake (i7-7567U CPU @ 3.50GHz): 1. ffmpeg -hwaccel qsv -c:v h264_qsv -i bbb_sunflower_1080p_30fps_normal.mp4 -vsync passthrough -vframes 1000 -c:v hevc_qsv -gpb 0 -bf 0 -q 25 test_gpb_off_bf0_kbl.mp4 transcoding fps: 85 encoded file size of test_gpb_off_bf0_kbl.mp4: 21960100 (bytes) 2. ffmpeg -hwaccel qsv -c:v h264_qsv -i bbb_sunflower_1080p_30fps_normal.mp4 -vsync passthrough -vframes 1000 -c:v hevc_qsv -gpb 1 -bf 0 -q 25 test_gpb_on_bf0_kbl.mp4 transcoding fps: 79 encoded file size oftest_gpb_on_bf0_kbl.mp4: 21211449 (bytes) In this case, enable gpb can bring about 7% performance drop but 3.4% encoding efficiency improvment.

* lavc/qsvenc_h264: remove the privite option trellisZhong Li2019-03-28
| | | | | | | | | | | | | | | | | | There are many problems of current qsv trellis option: 1. Duplicated with AVCodecContext definition 2. MFX_TRELLIS_XXX is introduced by MSDK API 1.17 Currently Without MSDK API checking thus may cause compilation issue. 3. user is inclined to enable trellis when set "-trellis 1", but actually it is to disable since MFX_TRELLIS_OFF is equal to 1. 4. It is too complex for user to enable trellis for every frame(I/P/B). Just simply remove the private option, and switch to the AVCodecContext definition. Compatibility should not a big problem (except can't exact map) since the option name is same as AVCodecContext.

* lavc/qsvenc: enable QVBR modeZhong Li2019-01-25
| | | | | | | | | | | | | | | | | QVBR mode is to use the variable bitrate control algorithm with constant quality. mfxExtCodingOption3 should be supported to enable QVBR mode. It is neccesary to specify a max_rate for QVBR, else it may be ICQ mode. Example usage: ffmpeg -hwaccel qsv -c:v h264_qsv -i input.mp4 -c:v h264_qsv -global_quality 25 -maxrate 2M test_qvbr.mp4 -v verbose Clip QVBR quality range to be [0, 51] as Mark's commments. It is similar to qp range of CQP but possibly should be updated when VP8/VP9 encoding can be supported. Reviewed-by: Mark Thompson <sw@jkqxz.net> Signed-off-by: Zhong Li <zhong.li@intel.com>
