Let’s be clear here: the Perl script does not “own” www-data. Your script may be running under that user’s permissions, but it is the OS that owns the user. The distinction matters because you must deal with the OS’s restrictions. > When my perl script executes the same command through exec(), but without > sudo permissions, I get videos that VLC can't open. I’m betting that you are running into an SELinux or AppArmor restriction. Under such MAC systems, user www-data is purposely disallowed from writing files outside regular HTTP locations: http://ubuntuforums.org/showthread.php?t=1324128 This is not a Live555 problem, it’s an OS misconfiguration problem. Instead of trying to beat AppArmor/SELinux into submission, I recommend that you move the bulk of your Perl script to a daemon (which may itself be a Perl script) which the original Perl script sends a message to when it gets a web request that needs to start openRTSP. You are spoiled for choice when it comes to ways to pass that message: http://perldoc.perl.org/perlipc.html http://search.cpan.org/search?query=ipc&mode=all https://metacpan.org/search?q=ipc&search_type=modules All of this is off-topic here, so if you need further help, take it up on a Perl, Apache, Ubuntu, etc. forum. No change to openRTSP can reasonably be expected to fix this class of problem. _______________________________________________ live-devel mailing list live-devel@lists.live555.com http://lists.live555.com/mailman/listinfo/live-devel
