Lynne	20de09a6de	h264_ps: expose scaling_matrix_present_mask Vulkan requires it. It technically also requires use_default_scaling_matrix_mask, but we can just be explicit and give it the matrix we fill in as-non default.	2 years ago

Anton Khirnov	a4611e3170	lavc/decode: pass AVHWAccel instead of AVCodecHWConfigInternal to hwaccel_init() The only thing besides the hwaccel that this function uses from AVCodecHWConfigInternal is the pixel format, which should always match the hwaccel one. Will be useful in following commits.	2 years ago

Haihao Xiang	943a42fc54	lavc/qsvenc: make sure continuous allocation Intel MediaSDK and oneVPL expect continuous allocation for data[i], however there are mandatory padding bytes between data[i] and data[i+1]. when calling av_frame_get_buffer. This patch removes all extra padding bytes. Signed-off-by: Haihao Xiang <haihao.xiang@intel.com>	2 years ago
Haihao Xiang	cf79dab8df	lavc/qsvenc: avoid data copy if possible The data copy is unnecessary for packed formats when frame width and height are aligned For example: $ ffmpeg -f lavfi -i testsrc=size=1920x1088 -vf "format=yuyv422" -c:v hevc_qsv -f null - Signed-off-by: Haihao Xiang <haihao.xiang@intel.com>	2 years ago
