Description

While i was debugging why chrome is stalling av1 streams in my broadcast box instance it turned out that chrome has a bug with handling obu-paddings (I'm working on sending a patch there + libdatachannel) this won't fix it for bbox since it forwards packets, and it's just work around for users who use rtp depacketizers
