I'm trying to use jitter buffer interceptor.
I expect to receive RTP packets as usual, but in correct order.
I receive invalid RTP packets. The payload length is more than expected. The payload is filled by zeroes.
The interceptor tries to unmarshal the whole buffer and doesn't respect the actual packet length. https://github.com/pion/interceptor/blob/142f17f90b527434b62ce2fd92676e6e262cd807/pkg/jitterbuffer/receiver_interceptor.go#L77
It looks like we should replace packet.Unmarshal(buf) to packet.Unmarshal(buf[:n])
packet.Unmarshal(buf)
packet.Unmarshal(buf[:n])
