Hi Timo,
Thank you for your review. Sorry for both superfulous spaces. Thank you for
pointing them out, I will be more careful on the next patches. Please check my

This idea could be extended to other fields not presently considered to
be metadata, that would be handy to treat as such.
I use the key "id" because ffprobe outputs id= for streamid. Another
option could be to collect these types of metadata that go into
AVStream fields under a namespace like FFM
