2019-04-03lavc/qsvenc: enable hevc gpb optionZhong Li
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.

2019-03-28lavc/qsvenc_h264: remove the privite option trellisZhong Li
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.

2019-01-25lavc/qsvenc: enable QVBR modeZhong Li
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>

Add VDENC(lowpower mode) support for QSV H264 It's an experimental function(like lowpower in vaapi) with some limitations: - CBR/VBR require HuC which should be explicitly loaded via i915 module parameter(i915.enable_guc=2 for linux kernel version >= 4.16) Use option "-low_power 1" to enable VDENC.

Purpose: qsvenc: make sure that interlaced encoding works. Also, reduce the vertical alignment constraint when possible to reduce memory usage.
