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>	2018-04-08 20:47:59 +02:00
Huang, Zhengxu	a5a6ac1a12	libavfilter/overlay_qsv: Add QSV overlay vpp filter ... The filter supports two inputs and (implicitly) scaling the second input during composition, unlike the software overlay. The code has been separated into common interface and qsv overlay implementation. The common part mainly creates the qsv session and manages the surface which is nearly the same for all qsv filters. So the qsvvpp.c/qsvvpp.h API can be used by other QSV vpp filters to reduce code redundancy. Usage: -hwaccel qsv -c:v mpeg2_qsv -r 25 -i in.m2v -hwaccel qsv -c:v h264_qsv -i in.h264 -filter_complex "overlay_qsv=eof_action=repeat:x=(W-w)/2:y=(H-h)/2" -b 2M -maxrate 3M -c:v h264_qsv -y out.h264 Two inputs should have different sizes otherwise one will be completely covered or you need to scale the second input as follows: -hwaccel qsv -c:v mpeg2_qsv -r 25 -i in.m2v -hwaccel qsv -c:v h264_qsv -i in.h264 -filter_complex "overlay_qsv=w=720:h=576:x=(W-w)/2:y=(H-h)/2" -b 2M -maxrate 3M -c:v h264_qsv -y out.h264 Signed-off-by: ChaoX A Liu <chaox.a.liu@gmail.com> Signed-off-by: Zhengxu Huang <zhengxu.maxwell@gmail.com> Signed-off-by: Andrew Zhang <huazh407@gmail.com> Change-Id: I5c381febb0af6e2f9622c54ba00490ab99d48297 Signed-off-by: Maxym Dmytrychenko <maxim.d33@gmail.com>	2017-09-17 19:59:06 +02:00
