I wanted to try this VDPAU thing, but I don't seem to have even a single MPEG1 or MPEG2 video here, lol. Everything these days is something MPEG4-based. Which is probably why I get this error:
A: 0.0 V: 0.0 A-V: 0.000 ct: 0.000 0/ 0 ??% ??% ??,?% 0 0
Movie-Aspect is 1.33:1 - prescaling to correct movie aspect.
VO: [vdpau] 640x480 => 640x480 Planar YV12
[vdpau] Error when calling vdp_presentation_queue_get_time: No backend implementation could be loaded.
FATAL: Cannot initialize video driver.
