That's about right. In all seriousness, I'd be interested moving to
use a more standard container of similar complexity for providing
basic packet framing and timestamping. I thought about (ab)using RTP,
but never had the time to look into it very far and given the limited
use/scope of ivf, there weren't any tangible advantages at the time.
If you have any suggestions, I'd be interested.
