[Qt-interest] QTimer on Windows in Unreliable for Small (16ms - 30ms) Delays

[Martin Schröer]

Hey Josiah,

for tasks similar to yours (doing anything with a video clip sync'ed to 
the clip)
i stopped relying to any timer, but started to sync up with the frame count
/ playback time instead.

So most of my video apps don't use timers directly, but instead use timed
(timer event) calls to a function that then checks the current frame / 
pb time
of the clip and set some needed data according -and sync'ed- to the clip.

That way always worked well for me, not only since using Qt ;]

Using phonon, you would use Phonon::MediaObject::tick() and
Phonon::MediaObject::currentTime() to do so.

See the Qt Reference to learn about phonon.
