So, I have been working with FFMPEG on a project that involves streaming video from one computer to another across the internet with RTP. I want to take that into ffmpeg and use ffserver to display it on a local network.
As I understand it, you need to have a SDP information so that the receiving ffmpeg instance can interpret the RTP stream. Despite what webpages say, I can not find the SDP information in the information printed to the console.
How can I force the transmitting ffmpeg instance to output the SDP information so that I can use it to configure my receiving end?
Right now, I am testing on Windows 7, but the final solution will be on linux.
The command I'm running for testing is
ffmpeg -fflags +genpts -i files\2005-SFSD-sample-mpeg1.mpg -threads 0 -r 10 -g 45
-s 352x240 -deinterlace -y 2005.mp4 -an -threads 0 -r 10 -g 45 -s 352x240
-deinterlace -f rtp rtp://192.168.200.198:9008
My ffmpeg information is...
