I am working on putting together a new hardware configuration for our main node and we are testing the new 4 (s-video) input card from Winnov (Videum Quattro). After receiving some new drivers from Winnov, I seem to have the card installed properly (I can see video in their included software).
However, the card does not show up as an option in the Manage My Node dialogue when I try to add a VideoProducer service. I've seen this problem in the past with multiple Osprey cards, and currently I am using the edit that Darran Edmundson sent to the list last July (see below). I could do the same thing, but the card doesn't even show up as a device option in vic (so I don't know the name of the resource to append to the resource list). I would really appreciate the help getting this card working as soon as possible. Thanks, Chris From: Darran Edmundson [mailto:[email protected]] Sent: Tuesday, July 06, 2004 1:31 AM To: [email protected] Subject: [AG-TECH] hack to solve Osprey problem under AGtk2.2 and WinXP ... Problem: For nodes with multiple Osprey cards running AGTk-2.2 under Windows XP, multiple instances of vic contend for the same capture card. The workaround is to manually resolve the vic contentions after changing venues. This is a pain. Pending a proper fix, you might wish to try the following. It works for us - your mileage may vary. Hack: 1) On your video machine, open the file c:\Python23\Lib\site-packages\AccessGrid\Platform\win32\Config.py Save a copy of this file so you can undo the following if necessary. 2) Line 985 should be the definition of the SystemConfig class method GetResources: def GetResources(self): """ Return a list of the resources available on the system """ ... 3) This method builds a list of AGVideoResource entries (one for each capture device) by scanning your Windows registry. Our registry did not contain entries for both Osprey cards. Rather than change the registry, the following hack sets the list of "found" resources explicitly. Around line 1020, a return statement sends back the list of discovered resources. Insert the following code indented the same amount as the final return statement. # hack to hardcode known resources resourceList = list() resourceList.append( AGVideoResource( 'video', 'o100vc.dll - Osprey Capture Card 1','producer', ['external-in'])) resourceList.append( AGVideoResource( 'video', 'o100vc.dll - Osprey Capture Card 2','producer', ['external-in'])) resourceList.append( AGVideoResource( 'video', 'o100vc.dll - Osprey Capture Card 3','producer', ['external-in'])) print "hack to hardcode known video resources ..." return resourceList 4) Save and restart your video machine AGServiceManager. You should see the "hack to hardcode .." print statement output. 5) "Manage my node" and remove and re-add the VideoProducer services. You should be prompted for the desired resource. 6) Let me know if it works ...
