well, I imagined main use for this format will be just encoding h264 wuth pcm sound (something ffmpeg refuses to do)

Instead "h264_vaapi.mkv" gives me error and no rendering.

Error message popup:
"error rendering data"

On terminal:
FFMPEG::encode_activate: write header failed /home/paz/vaapi_test.mkv
err: Invalid data found when processing input

strange, will retest when I actually return to home...
