For some reason whenever i execute the above command without loglevel
debug the command hangs. when trying to troubleshoot with the debug
command it is running fine and without any problems except for the
overhead of the extra logging.
I am in no way capable to troubleshoot why this might be happening but if
any information is required id be glad to provide.
Some extra info:
SDI card=Decklink Quad2
happens on all SDI outputs =yes
happens without audio input =seems not to for some reason.
$display and $GPIO are pushed from other scripts but can be hardcoded to
be display :11 and GPIO 1-7.
