Usually a HW decoder is expected when user specifies a HW acceleration method via -hwaccel option, however the current implementation doesn't take HW acceleration method into account, it is possible to select a SW decoder. For example: $ ffmpeg -hwaccel vaapi -i av1.mp4 -f null - $ ffmpeg -hwaccel nvdec -i av1.mp4 -f null - $ ffmpeg -hwaccel vdpau -i av1.mp4 -f null - [...] Stream #0:0 -> #0:0 (av1 (libdav1d) -> wrapped_avframe (native)) libdav1d is selected in this case even if vaapi, nvdec or vdpau is specified. After applying this patch, the native av1 decoder (with vaapi, nvdec or vdpau support) is selected for decoding(libdav1d is still used for probing format). $ ffmpeg -hwaccel vaapi -i av1.mp4 -f null - $ ffmpeg -hwaccel nvdec -i av1.mp4 -f null - $ ffmpeg -hwaccel vdpau -i av1.mp4 -f null - [...] Stream #0:0 -> #0:0 (av1 (native) -> wrapped_avframe (native)) Tested-by: Mario Roy <marioeroy@gmail.com> Signed-off-by: Haihao Xiang <haihao.xiang@intel.com> Signed-off-by: Anton Khirnov <anton@khirnov.net> |
