[FFmpeg-user] VDPAU seems to be unable to decode H.264 High 4:4:4 Predictive

It seems that when using the -hwaccel vdpau option for FFmpeg on Linux, 
FFmpeg can decode an H.264 video encoded with the High profile fine, but 
it cannot decode a video I encoded in High 4:4:4 Predictive. It returns 
this error:

No known VDPAU decoder profile for this stream.
vdpau hwaccel requested for input stream #0:0, but cannot be initialized.

Is this because the FFmpeg developers have not implemented this yet, or 
does nVidia's VDPAU library not support the ultra-high profiles such as 
High 4:4:4 Predictive?
