Subject: [FFmpeg-devel] [PATCH v2] libavcodec/qsvenc: add more ChromaFormat support to mjpeg_qsv
Date: Mon, 21 Feb 2022 15:28:33 +0800
Message-ID: <20220221072833.967303-1-wenbin.chen@intel.com> (raw)
ChromaForamt for mjpeg-qsv is always set to yuv420, and this will be
wrong when encode other pixel format (for example yuyv422). ChromaFormat
is changed to be adaptive to pix_fmt.
