First, please upgrade to the latest version of the code (the only version that
we support). See
http://live555.com/liveMedia/faq.html#latest-version
(The version of the “LIVE555 Streaming Media” code included in Linux ‘distros’
is often woefully out-of-date.)

However, that’s not what you’re doing, based on the command-line options that
you gave:
> Core was generated by `/usr/bin/openRTSP -v -c -B 10000000 -b 10000000 -4 -Q
> -f 30 -F 2016-09-20 -d 86’.
Note that the “-v” and “-4” options cause output to go to ‘stdout’ (and thus
the "-F <fileName-prefix>” option is ignored). Also, the “-d 86” option causes
the program to read the stream for only 86 seconds each time (and then the “-c”
option causes it to reopen the stream again afterwards).
Also, because you’re using the “-4” option (to generate a “.mp4"-format file),
you should also include not just the "-f <frame-rate>” option, but also the “-w
<width>” and "-h <height>” option; see
http://live555.com/openRTSP/#quicktime
If you want to generate multiple output files - once every 30 minutes, then way
to do this is with the option
-P 1800
and omit the “-c” and “-d” options.
However, I suggest that you first make sure that you can generate a single
playable video file, by running
openRTSP -4 -B 10000000 -b 10000000 -f 30 -w foo -h bar -d 30
rtsp://mumble > test.mp4
(Replace “foo”, “bar”, and “mumble” with actual width, height, and URL.)
This will (after 30 seconds of streaming) generate a file “test.mp4”. Make
sure that it’s playable. Then, and only then, should you run
openRTSP -4 -B 10000000 -b 10000000 -f 30 -w foo -h bar -P 1800
rtsp://mumble
which will generate an output file every 30 minutes.
