"- high latency playback using alsa"
Huh? Sorry, i want low latency audio (:

Please fix description :P

It's not an error.
You don't need low latency audio for music playback.
But by using the maximum audio buffer size, Qt Media Player doesn't need to wake often (e.g only 3 time per second on my PC).
This is especially useful to save power on embedded systems.

qmake tries to autodetect KDE using kde4-config.
you can disable it by editing the .pro file.
it is only used to have an improved file dialog

Sorry, I forgot to try to compile as 32bit.
http://gitorious.org/qt-media-player should now work.
If checking out a git snapshot is too inconvenient, I can package a new archive.
Thanks for testing and reporting bugs.

you can either use ffmpeg 0.6 or simply remove the line.
