[Live-devel] waiting for SPS/PPS

[Matthew Czarnek]

Hey Chris, sure I'll share how to do it now quickly.

I got the CMake file working so that it creates a Visual Studio solution
that allows you to compile openRTSP, could easily be changed to run other
test programs. In order to run it with my own code, I then created my own
class that subclassed FramedSource and allowed me to use my own subclass
along with the live555 RTSPServer. Would take me a little bit to remember
everything I did there to get it working. But also got it working via CMake
(plus lots of work on top of that within Visual Studio).  Oh and if you are
considering something other than live555.. I started with ffmpeg, however
it turned out that I got more than 10x lower CPU usage and much less memory
too using live555 as an RTSP server.  I'd definitely recommend it.

You'll want to download and set up the CMake tool and run the GUI:
https://cmake.org/runningcmake/

Set the source code path to the directory that includes the CMakeLists.txt
file(must be named CMakeLists.txt) that is used to build the solution. Set
the Build path to the location you want the VS Solution and project files
to be output.

Good luck, let me know if you have any CMake questions.
Matt


This is the CMakeLists.txt file I used:
