Using an x86 and ver 2.1.0. One instance of VLC records the full hour. If I add a second instance to the batch script the last instance works fine, the first instance stops typically after 3 minutes but occasionally varies something short of the full record. Seems the "--run-time=x" may be getting fouled. Tried running two separate scripts in the windows scheduler offset by 1 minute and the results were worse and more random. In all cases the scripts are killed by the scheduler 1 minute after calling the script shown below.

Is there a minor script change that will resolve this or is another non-relative method having a absolute time "end" command needed? Don't find an attachment option so I included the script in this message.

Thanx...

Could it be caching needs to be more liberally set for multiple instances to co-exist? Does anyone know the default values for these if not specified in the script?

--file-caching specifies caching for local files,
--network-caching specifies caching for network resources,
--live-caching specifies caching for capture devices and
--disc-caching specifies caching for local optical media

Even tried this simple script and find the first instance will record for 3 minutes and the second instance will be continuous record. So it has nothing to do with the --run-time or --play-and-exit commands.

@echo off
start vlc -vvv rtsp://user:pw@x.x.x.x:554/mpeg4cif --sout=file/mp4:"H:\Surveillance\VideoCam1\test.mp4" --qt-start-
start vlc -vvv rtsp://user:pw@x.x.x.x:554/mpeg4 --sout=file/mp4:"H:\Surveillance\VideoCam2\test.mp4" --qt-start-
EXIT

Looks like I'm not the only one struggling with this.
