I also have issues, but not related to bpyramid. For instance, mplayer (very latest CVS) plays raw h264 files double speed,

How does mplayer read raw H.264?

it has its own demuxer

For fixed framerate streams, H.264 specifies the field rate, even when using progressive encoding. There has been some confusion about this in the past, with the result that some codecs take the numbers to mean frame rate for progressive sequences. Hence the double speed. This was fixed in lavc and x264 in January. If mplayer uses its own H.264 "demuxer", or uses an old version of lavc, it would show this problem.

do you mean that when fixed_frame_rate_flag in vui_parameters() is set the nominal framerate should be halved?
