Video doesn't play on Yosemite aka 10.10

I updated to yosemite on one of my computers and it can't play videos anymore. Pictures are shown without a problem.

This is the output of air debug :

This will run some basic tests on your network trying to find errors
and debug information to help fix them.

And this is the error I get:
