I try with other file type it still works, and with vlc compiled program it works file. But, with libvlc in QT Program I got the following message, and no sound.

The output:

Code: Select all

maybe your compiled vlc and your libvlc are not the same version

H264-MPEG4, No sound?

I have checked, all of vlc packages is the same (1.1.8 ). I found that the original is .mov file (Quicktime Movie), not .avi!

I open my .mov with vlc by File > Open File ...

My source code with libvlc is a copy in http://wiki.videolan.org/LibVLC_SampleCode_Qt

PS: What happen with this forum in few days ago, i can not login, can not post or edit, ... always return 404 error message

compare the logs from vlc and from libvlc to see the difference.

Yes, I have. But nothing different between them.

I try to open vlc on terminal with vlc -vvv and compare with log created by qt program. It's the same. So I don't know why it does not works with QT program.

so you have this warning with both vlc and libvlc ?
[0x7f6d18001a70] mp4 stream warning: unknown box type colr (incompletely loaded)

I never used audio output with libvlc. Maybe you have to set the audio output with these functions :

yes, in both

I haven't set audio output. In Fedora 13, this works fine, this problem occurs when I upgrade to fedora 14.
