I was trying to run MPEG-4 video and H.264 videos using Qt/Phonon Version 4.5.1 on Red Hat Linux 5.3.
I have installed the gstreamer and devel packages and MPEG3 codecs.
Am not finding the MPEG-4 -video codecs and when I tried playing MPEG-4 videos phonon complians it needs h.264 codecs need to be installed.
So if anyhow have tried playing MPEG-4 videos or H.264 videos please do specify the site where to download them.
Thanks in advance.
