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

[André Somers]

Hi,

Well, I never got Phonon to run on Linux myself. I did not give it a lot of
effort in trying either, by the way. I don't need it for my own projects, so
why bother. I am a bit surprised that Trolltech/Qt Software ships a part
that is so hard to get working everywhere. I thought Qt was about having
your stuff just work on all supported platforms...
Having said that: Linux should be easy in that respect. One quick route
would be to just install a KDE based distribution. KDE uses Phonon
everywhere (it was developed for KDE originally), so that should get you
started on phonon!

Still, I am wondering a bit why you try to do this from scratch. I mean: why
not take a look at existing Qt based video players and look how they do it,
or even just modify them? Also displaying text over the video display should
be a solved problem: video players that display subtitles do it all the
time... I have never tried to build an application like this myself, so I
don't know about the little pitfalls around videodisplay myself. It just
sounds like you are trying to re-invent the wheel...

André

Same here - on linux, I spent a long time trying to compile phonon - 
never did have any getting it to run. 
(http://www.mybryanlife.com/blog/josiah/2389). On windows, I've tried 
multiple times to compile it with the "Qt command prompt" - e.g. going 
into c:\qt\qt...\ and doing configure, then mingw32-make - each set of 
attempts has resulted in different problems. I can try to recreate if 
anyone cares, but bottom line is that I found it *way* too difficult to 
get phonon working - after about a week of on-again, off-again working 
on it in my personal time, i gave up. Anybody have any binaries or 
how-to's would be welcome.
