Linjie Fu	e716323fa8	qsvenc: Add VDENC support for H264 and HEVC Add VDENC(lowpower mode) support for QSV h264 and HEVC 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 kerner version >= 4.16) - HEVC VDENC was supported >= ICE LAKE use option "-low_power 1" to enable VDENC.

Dmitry Rogozhkin	c1bcd321ea	avcodec/qsv: fix async support Current implementations of qsv components incorrectly work with async level, they actually try to work in async+1 level stepping into MFX_WRN_DEVICE_BUSY and polling loop. This change address this misbehaviour.

Zhong Li	4ce701b4e6	qsvenc: remove vcm option on Linux 1. vcm mode is only available for H264. 2. vcm is not supported on Linux, but it is shown when run "./avconv -h encoder=h264_qsv \|grep vcm". This shouldn't happen. Signed-off-by: Zhong Li <zhong.li@intel.com> Signed-off-by: Maxym Dmytrychenko <maxim.d33@gmail.com>	7 years ago
Maxym Dmytrychenko	cca5e4f040	qsv: adding Multi Frame Encode support Starting from API 1.25 helps to improve performance of the simultaneous encode, 1:N scenario, like: ./avconv -y -hwaccel qsv -c:v h264_qsv -r 30000/1001 -i ~/bbb_sunflower_1080p_60fps_normal.mp4 -vframes 600 -an \ -filter_complex "split=2[s1][s2]; [s1]scale_qsv=1280:720[o1]; [s2]scale_qsv=960:540[o2]" \ -map [o1] -c:v h264_qsv -b:v 3200k -minrate 3200k -maxrate 3200k -f rawvideo /tmp/3200a.264 \ -map [o2] -c:v h264_qsv -b:v 1750k -minrate 1750k -maxrate 1750k -f rawvideo /tmp/1750a.264 Signed-off-by: Maxym Dmytrychenko <maxim.d33@gmail.com>	7 years ago

Vittorio Giovara	0e6c853221	lavc: Move b_frame_strategy and b_sensitivity to codec private options The b_frame_strategy option is only used by mpegvideoenc, qsv, x264, and xavs, while b_sensitivity is only used by mpegvideoenc. These are very codec-specific options, so deprecate the global variants. Set proper limits to the maximum allowed values. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
