Example for Video Transmission via RTP instead of DataChannel (ESP32)

Feature Request: Example for Video Transmission via RTP instead of DataChannel (ESP32)

Description

I am using the ESP32 example provided in the libpeer project for video transmission, and noticed that the current implementation uses DataChannel to send video data.

However, for my use case (low-latency real-time video streaming on ESP32), RTP (Real-time Transport Protocol) is more suitable for media transmission (it is the standard protocol for WebRTC media streams, optimized for real-time audio/video).

I would greatly appreciate it if you could provide a complete example of video transmission using RTP channels instead of DataChannel for the ESP32 platform.

Any guidance, code snippets, or a complete example would be extremely helpful. Thank you for your work on libpeer!

I'd like to add a follow-up note to this request:

I noticed there's a peer_connection_send_video method in the current implementation, and its underlying transmission uses RTC (instead of DataChannel). However, when I tried using this method to send video from the ESP32, the corresponding stream on the web client side fails to render any image (the video element stays blank).

Could you also help troubleshoot this issue (or include relevant handling in the RTP example)? Specifically, I need to confirm:

1. Whether peer_connection_send_video is actually utilizing RTP for media transport
2. What configurations (e.g., codec parameters, SDP negotiation) are required to make the web client correctly decode and display the video stream sent via this method

Thanks again for your assistance!
