    Can't Play .mp4 files


    I just decided to turn loose Windows 8 RP on "bare metal" here as opposed to a VM. I didn't even bother to mess with video under a VM, but with the bare metal install, I've run into some trouble.

    At first, media player didn't seem to play anything, including .wmv files. Messing around, I unchecked the "Direct X acceleration" box and that allowed it to play .wmv files. However, it still won't play .mp4 files -- no video, just sound, and Media Player will hang trying to exit.

    It did this with a clean install with only the Windows supplied video driver. My video card has been obsoleted by AMD now (HD 4200 chipset) and I couldn't use the new Windows 8 preview driver package, but I did try intalling the AMD 12.4 driver in Win7 compatibility mode. That worked fine it seems, but it still won't play .mp4 files. Turning the Direct X acceleration back on still kills .wmv playback as well.

    Any ideas? Win7, both x64 and 32-bit played .mp4 files fine right out of the box on this machine.

    I see this got moved to audio. To be clear this is a problem with .MP4 *video*, not an audio problem. .MP4 may look too close to .MP3 or something.

    This won't be helpful, but I have no trouble playing .mp4 videos.

    I have the X64 version of Win 8 RP, an NVidia GTX 680 graphics card, and WDDM 1.2 drivers.

    Try some CCCP
    CCCP - Combined Community Codec Pack

    It includes media player classic and a bunch of codecs.

    Or download VLC.

    Or go to the app store and install the media center app.

    Yes it is one of the new "features" of Windows 8 where they removed mpeg 4 playback for your convenience...

    Ah, so they removed the .mp4 codec(s) from Windows 8? That would explain it. Thanks for the replies, and I'll try installing the codec packs and/or the media center app when I boot up Win 8 again shortly. I'll post the results.

    Still no joy. I installed the Media Center "Feature Upgrade", which didn't help, then the Shark Codec package and still no joy. Something is screwed up and I'm wondering if a re-install would fix it. When it tries to play an .mp4 file, the window will resize to the proper resolution size but it will not display video. Hitting the stop button will cause Media Player to hang, requiring it to be killed via Task Manager.

    The preview thumbnails in Explorer seem to work for all the .mp4 files, showing the first frame from the clip properly.

    I'm going to install one of the third party players and see if they will work.

    Can you provide a link to a generally available .mp4 file that won't play for you?

    I'd be willing to see whether it works with my Windows 8 X64 RP installation. I don't recall installing any video codec packages, but I seem to have the Media Player.
