aside: how was this position in the enum determined?

Oh, this CL is about a month old now, I don't remember TBH. Perhaps I thought
that Vorbis was the last video codec in this list and FLAC would be the first
audio codec. But looking closer at the list now, the ordering here seems to be
completely random.

It is audio then video. This should probably go after OPUS.

Doesn't matter, but done.

     H264,
     HEVC,
