how to change directshow backend to phonon-vlc backend in Windows

[Seishin]

Thanks for your replying. Do you mean Qt does not support phonon-vlc backend now?

I think that is effectively what it says.

I see. But isn't the VLC media player written in Qt with phonon and VLC backend? Or actually they didn't use the Qt phonon?

Qt backends were supported... but not in recent versions of qt.

This looks like reducing the power of Qt...I'll try to find another way to support mp4 (Maybe shipping the directshow codec with program?). Thanks a lot.

Hello,

I am trying to play rawvideo(not compressed) in HD 1920x1080 with Phonon VideoPlayer. It works if the videos size are small (1Go) but if not the player crash.
I check the buffering process and only around 2Mega of datas are send to the buffer.
With my videos size, I need to send more datas in the buffer(buffer size 8 Go). The problem is that I don't know how control the process.
Do you think it can be link with the backend I use?
I install DirectX and Directshow but I can't configue it. Do you know if it's possible?
I don't even knows what's the backend I use in phonon. Where can I find the information?
