Reduce video latency by 1 frame by not waiting for the next frame to signal us to give the current frame to the decoder. Also avoid giving partially reconstructed frames to the depacketizer because it can get confused with certain packet loss patterns.

Leave the zero padding bytes on FEC-recovered packets alone. Decoders are required to cope with trailing zero bytes in NALUs and they are not safe to remove because they may actually be part of the byte stream itself.
