No. Not yet. We're interested in people with more OS X or Win32
knowledge and time to help us with that.

No. We don't have dshow element wrapper plugins. See above. ;).

Like 'play at twice normal speed'? Or 'play at 25 fps and 44,1 kHz'? As
for the first, yes, we have elements for that, btu they're not part of
playbin. You can create a bin (with a ghost pad) containing the actual
video/audiosink and the speed-changing element for this, and set that
element as video-sink or audio-sink property in playbin. The
audio-element is called 'speed', the video-element is called 'videodrop'
(although that appears to be deprecated in favour of 'videorate', which
again cannot do this, so this may not work at all in the end). For
forcing frame/samplerates, see audioscale and videorate. Audioscale is
part of playbin.

Yes, that's how we use it too.
