The SDK will return error if feeding h264_qsv encoder p010 input. $ ffmpeg -f lavfi -i testsrc -vf "format=p010" -c:v h264_qsv -f null - [...] [h264_qsv @ 0x55584888b080] Current pixel format is unsupported [h264_qsv @ 0x55584888b080] some encoding parameters are not supported by the QSV runtime. Please double check the input parameters. Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height Signed-off-by: Haihao Xiang <haihao.xiang@intel.com>
