Yes. 10bit was forced but it does not improve play back with it off for either qsv/vaapi. latest files I tested: video starts playing but only the vlc logo is shown for about 5 seconds, then garbage pixels over the picture appears for another 5 seconds. picture is normal by 10 seconds. skipping forward in video still causes all audio to cut out. # ffprobe -v error -select_streams v:0 -show_entries frame=key_frame,pts_time \ -of csv=p=0 qsv-x265.mkv | awk '$2 == "1"' | head -5 ^C # ffprobe -v error -select_streams v:0 -show_entries frame=key_frame,pts_time \ -of csv=p=0 vaapi-x265.mkv | awk '$2 == "1"' | head -5> ^C # ffprobe -v error -select_streams v:0 -show_entries frame=key_frame,pts_time -of csv qsv-x265.mkv | grep ",1$" | head -5 ^C # ffprobe -v error -select_streams v:0 -show_entries frame=key_frame,pts_time -of csv vaapi-x265.mkv | grep ",1$" | head -5 # ffprobe -v error -select_streams v:0 -show_entries frame=key_frame,pts_time -of csv vaapi2-x265.mkv | grep ",1$" | head -5 ^C # ffprobe -v error -select_streams v:0 -show_entries frame=key_frame,pts_time -of csv qsv2-x265.mkv | grep ",1$" | head -5commands didn't seem to have output. no, didn't do a cpu encode, slow cpu. last resort.
