Only if the chained mpegts demuxer sets it, and it appears it doesn't.
Also, within the applehttp metadata, there is an explicit bitrate field
saying what the nominal bitrate of that variant is, we should pass it
through somewhere at least.
So, would a "variant_bitrate" metadata key be acceptable? Anton?
