Hello,
I'm new to AG development and I could use a hand with a fairly basic question.
Today I dug some more and found the VideoProducerService.py file in
...\Application Data\AccessGrid\local_services\. Under MapWinDevice,
the software iterates through the videum drivers and sets registry
keys for Source, Height, and Width.
keyStr = r"Software\Winnov\Videum\vic.exe%d" % (devnum,)
key = _winreg.CreateKey(_winreg.HKEY_CURRENT_USER,
keyStr)
_winreg.SetValueEx(key,'Source',0,_winreg.REG_DWORD,int(devnum))
_winreg.SetValueEx(key,'Height',0,_winreg.REG_DWORD,int(h261height))
_winreg.SetValueEx(key,'Width',0,_winreg.REG_DWORD,int(h261width))
_winreg.CloseKey(key)
It seems that this is were the source keys get set to 0, 1, 2, 3 and
where I would like to try setting them to something else. Can I just
edit this python file here and the changes will be implemented when I
run again? Do I need to repackage a VideoProducerService zip file and
install it with agpm?
I have tried editing the file in place and it seems that any change I
make causes the service to become unreachable. Even just adding in a
statement to print to the log file.
If anyone has a pointer on this, I would appreciate it. I'm appending
an excerpt from the VenueClient log to show the exception that I am
throwing.
Thanks,
Chris
