Re: [AG-TECH] Re: Winnov Videum Quattro

Chris:

I'm curious to know what in your configuration resulted in the
sources being numbered differently from how I would have expected.
If you uncovered anything in resolving this problem that could
result in a patch to the VideoProducerService, it might help other
people who are using the videum card.

I'll poke in my registry for indications of the source numbers, but
will be looking for your response.

Thanks,

Tom

Thanks Tom and Andrew.  I got the script corrected, so we now have a 4
s-video input card working with the AG software.  When I am back from
the holidays, I will have an opportunity to test it more thoroughly
and I'll send an email back to the list.

For those interested in the details, I had to modify the code that
sets the windows registry key that stores the source "variable" for
winnov cards.  Note that I'm using Tom's updated VideoProducerService
that maps these windows devices properly.  Although this is not the
order they are listed in, they sources needed to be 8,9,10,11 for the
s-video inputs.  It was a real joy to sort this out because not all
changes with the registry would go into effect without a reboot ;-)

Hi,

You can edit the file:
c:\documents and settings\<username>\Application Data\AccessGrid\local_services\VideoProducerService\VideoProducerService.py directly, and it should pick up the changes.  The problem might be that you have made a syntax error that means that the script cannot be run.  You can test this by running the script from the command line e.g. from the above directory run:
python VideoProducerService.py

This will at least test if the script is correct.

Andrew :)

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

After a long time off doing other things, I am returning to making
this card work in our AG setup.  I can successfully make the card run
if I configure each vic instance on transmit and set each to the
proper video source, but I can't make the software remember this
setting if I change venues.  It seems that the the settings are saved
in the registry here:

HKEY_CURRENT_USER\Software\Winnov\Videum\vic.exe0 [and 1,2,3]

But if I change the source key from the current settings of 0,1,2,3
then vic starts throwing error messages or else the settings get reset
to 0,1,2,3.  Is there a better way to make this setting stick?

The current source drop down list in the configure on transmit
dialogue shows the following source list to choose from.  The first
four are chosen by default, but I would like to choose the four Y/C
options for our s-video inputs.

A-Vid1
A-Vid2
A-Vid3
A-Vid4
A-Y/C 1 (Y:A-Vid1 C:A-Vid2)
A-Y/C 2 (Y:A-Vid4 C:A-Vid3)
B-Vid1
B-Vid2
B-Vid3
B-Vid4
B-Y/C 1 (Y:B-Vid1 C:B-Vid2)
B-Y/C 2 (Y:B-Vid4 C:B-Vid3)

Any help is greatly appreciated.

Thanks,
Chris
