| | | | | | | | | | | Add low latency P-pyramid support to qsv. This feature relates to command line option "-p_strategy". To enable this flag, user also need to set "-bf" to 0. P-strategy has two modes "1-simple" and "2-pyramid".

* lavc/qsvenc: allows the SDK runtime to choose LowPower/non-LowPower modesHaihao Xiang2021-08-12
| | | | | | | | | | | | | The SDK supports LowPower and non-LowPower modes, but some features are available only under one of the two modes. Currently non-LowPower mode is always chosen in FFmpeg if the mode is not set to LowPower explicitly. User will experience some SDK errors if a LowPower related feature is specified but the mode is not set to LowPower. With this patch, the mode is set to unknown by default in FFmpeg, the SDK is able to choose a workable mode for the specified features.

* 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. 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.

| | | | | | | | | | | | | | | | | 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.
