The driver documentation says "Hardware performance may vary
significantly between cards. No guarantees are made, nor implied, that
any particular combination of system configuration, GPU configuration,
VDPAU feature set, VDPAU API usage, application, video stream, etc.,
will be able to decode streams at any particular frame rate.". I think
that makes it clear enough that no specific supported frame rates are
implied.
