VLC 3.0 STDERR and STDOUT communication with parent not working
In VLC 2.x if you ran VLC as a slave/subprocess you could keep track of the debug output via STDOUT/STDERR pipes so long as the --no-quiet command line switch is used.
Monitoring STDOUT/STDERR doesn't work on VLC 3.0 which is problematic for Syncplay/syncplay.lua which relied upon that functionality to know whether or not things were working.
Problem encountered on both Windows and Fedora 24.
