Custom packetization/depacketization enables applications to do things such as:
- Encode with a custom (WASM) codec, packetize and send
- Observe incoming NACKs and resend with custom RTX behavior
- Observe incoming packets and customize when NACKs are sent
- Observe incoming packets
- Receive packets using a custom jitter buffer implementation
- Use WebCodecs for encode or decode, implement packetization/depacketization, a custom jitter buffer, and custom FEC
- Obtain a bandwidth estimate from RtpTransport, do bitrate allocation, and set bitrates of RtpSenders
