[AG-TECH] VideoConsumerService HD crash log

Fri Apr 8 10:25:55 CDT 2011

Hi Jason,
We, at 3 separate sites, have also seen this issue.  In our testing it appears to be 64bit related, since if we move the card(s) to a 32bit Windows machine (both Windows 7), the Vic crash does not happen and it all works fine.  We have also noticed that this affects multiple Viewcast Osprey card models, including the 440 (pci) and 450e (pci-express).  There is also some odd/inconsistent behavior where, if you disable the Osprey devices, open Access Grid Venue Client, then re-enable some (not always able to do all) of them, they will become available to add into a service, enter a venue, and actually work (send video through Vic).  Obviously this is not really a solution, but maybe some developers will find it valuable.
A while back Doug Kosovic was working on this some, I am not sure if he got anywhere with HD Vic to prevent the crashes.  Our workaround now is to use a 32bit capture machine to send SD video alongside our HD capture (which uses 3 Blackmagic Decklink SDI cards) and we control both HD and SD capture machines from our Display machine with Service Manager.
Since we've had this issue for almost a year now, we have had the opportunity to test with multiple releases of the 64bit drivers for these cards, hoping they would solve the problem, to no avail.  It appears Viewcast has now released all the beta versions, so theoretically the drivers should be stable, but I still consider that a possible cause.  It is interesting however that other capture programs appear to display the video from these Osprey cards just fine in 64bit Windows, so hopefully it is just a matter of modifying some HD Vic code.
Please let us know if you come up with or hear of a solution!  We are happy to provide logs or any other info upon request.
Thanks!
Keith

Colleagues
I am forwarding an issue from a colleague, in which an "Osprey 440e" device on Windows 7-64bit causes vic to crash.  Note, this issue only occurs on the newer version of vic (ie, The HD Video* services).  The non-HD Video Services appears to work fine.
If the device is disabled, vic appears to work fine.
Has anyone else seen this issue?
Many thanks,
Jason.
