R6025 - Pure virtual function call

I was just about to put my project through a vigorous testing session… but now when I open my VVVV patch I get a runtime error:

R6025 - Pure virtual function call

The rest of VVVV seems to be working fine.

Any ideas?

wow, never heard.

are you using any of the freeframe nodes, the beattracker or undistort in your patch?


I can edit and save the patch… but if I click on the error pop up it quits.


I can’t change the FFDshow codec on the compress node =/

Re-installing ffdshow seems to have sorted the problem!

nkay…so this sounds non-vvvv related. good to hear.
