nit: if we don't already DVLOG(1) entry.video_codec, this CL seems like a good
time to do that.

We already log codec info into media_log when parsing avcC/hvcC boxes, that
should probably sufficient (and we have more detailed information there, so if
we want more details we should expand logging there, instead of adding it here).

Acknowledged.
