Comment (by heleppkes):

 Its more likely that before this change it would just skip those frames
 entirely, while now it tries to decode them (and fails). This isn't
 technically a regression.

 I can only recommend you to fill fresh empty frames black when allocating
 them for DXVA2, that way you start with a black screen, and not a green
 screen, if decoding for some reason fails (like on badly cut streams like
 this one).
