Audio transcoding question

[TheDreadPirate]

Yes. It is encoding on the GPU.

Code:

Stream mapping:
  Stream #0:0 -> #0:0 (h264 (native) -> h264 (h264_qsv))
  Stream #0:1 -> #0:1 (copy)

"h264_qsv". You can also tell it is DEcoding on the GPU with this parameter in the ffmpeg command that is printed in the log.

Code:

-hwaccel vaapi

For the record, QSV is a superset of VAPPI. You can straight up use VAAPI on both Intel and AMD GPUs. But if you checked "Prefer OS native DXVA or VA-API hardware decoders" it will use VAAPI for decoding and QSV for encoding. And we recommend you keep it checked. VAAPI is slightly less performant that QSV, but more flexible for some odd ball video files.
