Convert file to AV1 using hw accel.

Hi !

i'm still confused... it runs through

[out#0/matroska @ 0x5c887ae3c840] video:0KiB audio:4666089KiB subtitle:28868KiB other streams:0KiB global headers:0KiB muxing overhead: 0.106630%

BUT it seems is only a file with audio :-(   (also again not activity in intel_gpu_top)

Do i need to setup which Codec the Input stream is ? in this case it would be  1080p H264 SDR
It seems that codec is not regognized (see picture)

Ciao Gerd
