ExtractUdpRtpPayload

Mainly used for extracting MPEG Transport Stream from pcap file (TS usually transmitted over UDP or RTP) but can also be used to extract UDP payload of any other protocol or data that gets transported over UDP/RTP. However, the file names it creates end in .ts.

Currently, this project heavily depends on libpcap and that is something I want to replace by using a native go library for pcap handling rather than a wrapper around libpcap.

Enjoy!

Create reader for pcap-ng file formats

Currently, gopacket/pcapgo only supports the original pcap format. By default, Wireshark (and its tools) now saves to pcap-ng format instead.

None of gopacket sub-projects that are written in native go support pcap-ng. So the only solution to this problem is writing our own pcap-ng reader, similar to gopacket/pcapgo. Likely this should be a separate project in github such that it can be reused.

Add support for reading RTP payload

Current version only supports UDP payload but often TS is transported over RTP. So support for that needs to be added as well. Have not yet found a native go package that is able to parse that though

Rework to use native go library for pcap read

Add unit tests
