Fei Wang	89ffcd1bbe	lavfi/qsvvpp: support async depth Async depth will allow qsv filter cache few frames, and avoid force switch and end filter task frame by frame. This change will improve performance for some multi-task case, for example 1:N transcode( decode + vpp + encode) with all QSV plugins. Performance data test on my Coffee Lake Desktop(i7-8700K) by using the following 1:8 transcode test case improvement: 1. Fps improved from 55 to 130. 2. Render/Video usage improved from ~61%/~38% to ~100%/~70%.(Data get from intel_gpu_top) test CMD: ffmpeg -v verbose -init_hw_device qsv=hw:/dev/dri/renderD128 -filter_hw_device \ hw -hwaccel qsv -hwaccel_output_format qsv -c:v h264_qsv -i 1920x1080.264 \ -vf 'vpp_qsv=w=1280:h=720:async_depth=4' -c:v h264_qsv -r:v 30 -preset 7 -g 33 -refs 2 -bf 3 -q 24 -f null - \ -vf 'vpp_qsv=w=1280:h=720:async_depth=4' -c:v h264_qsv -r:v 30 -preset 7 -g 33 -refs 2 -bf 3 -q 24 -f null - \ -vf 'vpp_qsv=w=1280:h=720:async_depth=4' -c:v h264_qsv -r:v 30 -preset 7 -g 33 -refs 2 -bf 3 -q 24 -f null - \ -vf 'vpp_qsv=w=1280:h=720:async_depth=4' -c:v h264_qsv -r:v 30 -preset 7 -g 33 -refs 2 -bf 3 -q 24 -f null - \ -vf 'vpp_qsv=w=1280:h=720:async_depth=4' -c:v h264_qsv -r:v 30 -preset 7 -g 33 -refs 2 -bf 3 -q 24 -f null - \ -vf 'vpp_qsv=w=1280:h=720:async_depth=4' -c:v h264_qsv -r:v 30 -preset 7 -g 33 -refs 2 -bf 3 -q 24 -f null - \ -vf 'vpp_qsv=w=1280:h=720:async_depth=4' -c:v h264_qsv -r:v 30 -preset 7 -g 33 -refs 2 -bf 3 -q 24 -f null - Signed-off-by: Fei Wang <fei.w.wang@intel.com> Reviewed-by: Linjie Fu <linjie.justin.fu@gmail.com> Signed-off-by: Zhong Li <zhongli_dev@126.com>	4 years ago

Linjie Fu	6895b350c3	lavf/qsvvpp: avoid the double-free when working in sys memory mode Currently, picref will be freed by calling av_frame_free(&picref) in submit_frame() in qsvvpp.c when working in system memory mode,and normally it is freed in filter_frame() in vf_vpp_qsv.c when working in other modes. Double free happens when working in system memory mode, remove to fix the memory issue. Reproduce: ffmpeg -init_hw_device qsv=foo -filter_hw_device foo -f rawvideo -pix_fmt nv12 -s:v 852x480 \ -i 852x480.nv12 -vf 'vpp_qsv=w=500:h=400' -f rawvideo -pix_fmt nv12 qsv.nv12 Signed-off-by: Linjie Fu <linjie.fu@intel.com> Signed-off-by: Zhong Li <zhong.li@intel.com>	6 years ago
Zhong Li	a5e1cb9e96	lavu/hwcontext_qsv: Add support for AV_PIX_FMT_BGRA. RGB32(AV_PIX_FMT_BGRA on intel platforms) format may be used as overlay with alpha blending. So add AV_PIX_FMT_BGRA format support. One example of alpha blending overlay: ffmpeg -hwaccel qsv -c:v h264_qsv -i BA1_Sony_D.jsv -filter_complex 'movie=lena-rgba.png,hwupload=extra_hw_frames=16[a];[0:v][a]overlay_qsv=x=10:y=10' -c:v h264_qsv -y out.mp4 Rename RGB32 to be BGRA to make it clearer as Mark Thompson's suggestion. V2: Add P010 format support else will introduce HEVC 10bit encoding regression. Thanks for LinJie's discovery.

Ruiling Song	d865783b6c	lavf/qsv: clone the frame which may be managed by framework For filters based on framesync, the input frame was managed by framesync, so we should not directly keep and destroy it, instead we make a clone of it here, or else double-free will occur. But for other filters not based on framesync, we still need to free the input frame inside filter_frame. Signed-off-by: Ruiling Song <ruiling.song@intel.com>	7 years ago

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>	7 years ago
