    Hello, all. I have an iMac G5. Running Leopard 10.5.2. It's working just swimmingly... except that it won't play back h264 video. I have the latest versions of both Quicktime and VLC.

    Each app handles the video files differently.

    Quicktime will give me this message:

    "The movie could not be opened.

    An invalid sample description was found in the movie."


    VLC will play the audio, but not the video.




    My computer can handle HD playback just fine (I watch most of my movies in 720p AVI files,) so that can't be the problem.


    This is just driving me insane. Does anyone have a solution for me?


    If this is in the wrong forum -- could a mod move it to the correct one, please?

    no? could be .mp4, .mov, .m4v... when i had some H264s that didnt work renaming them to .mov fixed them.

    can you open them with in QuickTime Player and save it as a self-contained movie?

    richthomas asked a legit question, there wasn't anything implied about your level of intelligence in his/her question.

    Anyway, if not even VLC can play back the video, then you're mostly likely screwed. Sounds like the h264 is either corrupt or else the container is corrupt. You can try using VisualHub to either remux or transcode (to mov if you want). Try remuxing first, if that doesn't work then try transcoding. If VisualHub can't read the file, then probably best to just give up.

    Try installing perian as it might replace the corrupted codecs.

    I have no idea if you're dumb. But clearly you don't have manners.

    I'm using OSXBMC to play all of my H.264 HD content now. Not that it will help in the case of the OP since I agree he probably has a screwed encode but the OS X port of XBMC is the only media player on the Mac (VLC, MPlayerOSX, Quicktime, etc included) that plays silky smooth 1080p H.264 in my experience.

    It's also a slick and maybe someday soon viable challenger for Front Row.

    Not sure I understand how it can playback better than mplayer since OSXmbc relies on mplayer to render its video.

    Don't you just hate it when that voice recognition software mixes up very similar words such as "where" and "we're?" ;)

    Huh? OSXBMC uses FFMPEG as does MPlayer. OSXBMC has no other relation to MPlayer that I know of. Even if it does use MPlayer code it is in much more active development with a new build out about every 2 weeks.

    OSXBMC plays 1080p content back smoothly on my 24" iMac that chokes or gets out of sync on both MPlayer and VLC.
