Comment:

 This problem does not happen if this patch set is installed
 (https://patchwork.ffmpeg.org/project/ffmpeg/list/?series=10318), and the
 command line is changed to:

 Note: I removed the hwupload,hwdownload from my original commands, that
 patch seems to have negated the need for those commands.
