  • lavu/opencl : replace va_ext.h with standard name

    lavu/opencl : replace va_ext.h with standard name

    Khronos OpenCL header (https://github.com/KhronosGroup/OpenCL-Headers)
    
uses cl_va_api_media_sharing_intel.h. And Intel's official OpenCL driver
    
for Intel GPU (https://github.com/intel/compute-runtime) was compiled
    
against Khronos OpenCL header. So it's better to align with Khronos.

  • nvenc : Add default value for AVCodecContext::refs

    8 juin 2017, par Srinath K R
    nvenc : Add default value for AVCodecContext::refs

    AVCodecContext::refs is used to control the DPB size to be used by the
    
encoder. The default value for AVCodecContext::refs as set in
    
libavcodec/options_table.h is 1.
    

    This patch sets AVCodecContext::refs to 0 for h264_nvenc and hevc_nvenc in
    
order to let the driver take the decision of the correct DPB size to use in
    
all cases.

  • lavf/qsv_scale : add scaling modes support

    lavf/qsv_scale : add scaling modes support

    low_power mode will use a fixed HW engine (SFC), thus can offload EU usage.
    
high quality mode will take EU usage (AVS sampler).
    

    Performance and EU usage (Render usage) comparsion on Intel(R) Xeon(R) CPU E3-1225 v5 @ 3.30GHz :
    

    High quality mode : ffmpeg -hwaccel qsv -c:v h264_qsv -i bbb_sunflower_1080p_30fps_normal_2000frames.h264 \

    - vf scale_qsv=w=1280:h=736:mode=hq -f null -
    
fps=389
    
RENDER usage : 28.10 (provided by MSDK metrics_monitor)
    

    Low Power mode : ffmpeg -hwaccel qsv -c:v h264_qsv -i /bbb_sunflower_1080p_30fps_normal_2000frames.h264 \

    - vf scale_qsv=w=1280:h=736:mode=low_power -f null -
    
fps=343
    
RENDER usage : 0.00
    

    Low power mode (SFC) may be disabled if not supported by
    
MSDK/Driver/HW, and replaced by AVS mode interanlly.
