Can you test with some light -c:v like again mpeg2 or mpeg4 ? I think it might fail without hwdownload,format=yuv420p filters in this case ... But I suspect it will abort earlier? May be ffmpeg 8.0 (at least as build for SuSE ) just complain at decoding moment, instead of just silently demuxing without decoding anything? What happen if you set hwaccel to none or vaapi ? I guess ot should decode in sw or via vaapi in such cases, so there will be more realistic decoding benchmark. It sort of sad even h264 does not transcode via Vulkan only. You can try to isolate was it (vulkan) decoder or vulkan encoder problem by forcing hwaccel to none while keeping -c:v at Vulkan encoder. Look out for hwdownload/hwupload and format filters, they still not inserted automatically, as far as I can see. Sorry if it sounds like too much work, as you noted this is a bit of bleeding edge so surprises happen. > bench: utime=18.656s stime=0.245s rtime=1.615s > bench: maxrss=197916KiB > > -----------------
