How to reproduce: {{{ ffmpeg -hwaccel cuda -hwaccel_output_format cuda \ -i /path/to/10bit-video -an -sn -dn -vf hwdownload,format=p010le -f null - ... [hwdownload @ 0000020612888240] Invalid output format p010le for hwframe download. [Parsed_hwdownload_0 @ 00000206106e7140] Failed to configure output pad on Parsed_hwdownload_0 [vf#0:0 @ 0000020610752240] Error reinitializing filters! }}} Regression caused by https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/30e6effff94c6f4310aa2db57191... For correctness and consistency with the old behavior, a change like this is required in the above commit: {{{ + } else { + frames_ctx->sw_format = sw_desc->comp[0].depth == 10 ? AV_PIX_FMT_P010LE : AV_PIX_FMT_P016LE; + } }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/11655> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
