Remember, You Have Complete Source Code.
If you have a specific suggestion for a patch to the implementation of the
“QuickTimeFileSink” class (the code that generates (depending on the value of
the “generateMP4Format” Boolean parameter) either a QuickTime-format file, or a
MP4-format file), then let us know.

That’s good. We support only the latest version of the code; the version that
you get from
http://live555.com/liveMedia/public/live555-latest.tar.gz

That’s strange. Your configuration file (“config.linux-mips”) includes the
definition
-DSOCKLEN_T=socklen_t
in COMPILE_OPTS. That should solve this problem. So you need to figure out
why the code (specifically, “GenericMediaServer.cpp”) is not actually being
compiled with this flag.
