Thanks for the contribution, would you read a few minor suggestions I write below?

Suggested change

	file-extension: rtmpdump
	file-extension: rtp

According to the page http://www.cs.cmu.edu/~./libra-demo/rtptools-1.17/rtptools.html you link, "the extension .rtp is suggested for files generated in rtpdump -F dump format", not .rtmpdump.

Thanks.

Before answering this, I see typos I made:

• The id should be rtpdump not rtmpdump;
• Same, the file-extension I wanted originally was rtpdump.

Now, regarding the extension, most of modern tools in the industries (commercial tools) use the .rtpdump extension as well as the modern open source tool Wireshark.

See an example of export on Wireshark, the most used tool today to generate such files:

Using only rtp as extension would look a bit conservative as it sticks to the command line rtptools recommendation but differs from people's custom today.

I commit a proposed fix to add the two extensions (original rtp and rtpdump widely in use today). I hope it is fine for your side.
