    Hi ,

    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.

    Fedora and Red Hat do not ship codecs in the main distribution due to legal issues. You need to install them separately from external repository:
    After installation you may verify presence of codecs with something like this:
    $ gst-inspect | grep 264
    typefindfunctions: video/x-h264: 264, x264, h264
    rtp: rtph264pay: RTP H264 payloader
    rtp: rtph264depay: RTP H264 depayloader
    h264parse: h264parse: H264Parse
    x264: x264enc: x264enc
