The vdpau_mixer could fail to be recreated properly if preemption occured at some point before playback initialization (like when using --hwdec-preload and the opengl-cb API). Normally, the vdpau_mixer was supposed to be marked invalid when the components using it detect a preemption, e.g. in hwdec_vdpau.c. This one didn't mark the vdpau_mixer as invalid if preemption was detected in reinit(), only in map_image(). It's cleaner to detect preemption directly in the vdpau_mixer, which ensures it's always recreated correctly.
