WebRTC Hacks

Debugging WebRTC media issues often requires unencrypted RTP payloads, and the improved *video_replay* tool now allows creating pcap files directly from Chrome. This tool, combined with Chrome's command line flags for logging RTP packets, provides detailed insights for troubleshooting. Extracting these logs and analyzing with Wireshark aids understanding packet contents. The *video_replay* tool built from libWebRTC helps in replaying and debugging video streams by configuring various command-line flags. Advanced features include exporting frames to JPEG or IVF formats and playing back audio using Wireshark or WebRTC's neteq_rtpplay binary.
