Comment (by mythtv@…):

 How fast do you expect the fastest decoder to be able to decode a frame?
 Is it going to make any significant progress in 100 ms?

 For anything that is near-realtime, like vdpau, it makes more sense to
 just start the display at the keyframe instead of spending 100 ms
 decoding, and then starting display close to the keyframe + 100 ms,
 especially if the 100 ms needs to be increased to something more like 500
 ms.  The only time you would ever want an exact-seek on a realtime decoder
 is for the single-frame, bookmark, and mythpreviewgen seeking.

 What about letting the decoder override the default seek accuracy, and
 setting it to -1.0 in the vdpau decoder?
