Some MPEG-4 files are audio only.

true, but the one that I have is a film, so it must have both audio and video.

You may be missing the video codec needed to play the file.

What file extension does this file have? .avi ? .mpg ?

I agree with kukm4, you may need to install the ffdshow filter in order to decompress this file.

p_ramezap, do you know what video codec was used to compress this file? If not, I would suggest installing MediaInfo, open the .mp4 file in MediaInfo, and let us know what video codec is being used.

john,

i donwloaded media info, and according to it, it requires a H.264 video stream and a AAC LC audio stream. It suggest Quick time stand alone player as codec, but wheni download and install that, i still have the same problme as before, there is audio but no video.

What kind of graphics card do you have? Also how fast is your CPU? h.264 is fairly intensive both on GPU and CPU.

It sounds like p_ramezap is having codec/filter problems, not graphics card problems.

I downloaded a sample .mp4 file encoded with H.264. Quicktime and Windows Media Player 9 won't play it. I was able to play it with the following players: VLC Media Player and mplayer. VLC might be more to your liking because mplayer lacks a GUI, you have to run it from a command line.

Hope this solves your problem!

(Edited to add that another option is to install the latest ffdshow filter (the one at the top of the page). Then you can watch H.264-encoded .mp4 files on Windows Media Player.)

Thanks John & kukm4, ffdshow did the trick, now i can view the MPEG 4 file using WMP.

If this is some dodgy porn flick you downloaded from p2p it could just be a corrupted file ?
