qt file format with wmv3 and wma3 codec can't played

I have some video files. the file container is qt file format, but video codec format is wmv3 and audio codec format is wma3. it can’t play at all. are there someone can help me. I appreciate it.

Interesting post. I’ve seen a similar case once: a DivX (fourcc DX50) encoded file in the QuickTime container. On my PC, QuickTime Player couldn’t play it, but Windows Media Player (with the DivX codec installed) could.
Sometimes people will have fun with certain tools and transcode from one container to another, outside what the codec was designed for. (I’ve been guilty of doing that on occasions).

It would help if you stated what platform you were on (PC or Mac), and how you know for sure the container and codecs of your media file.

My first try on a PC would be to play the file with Windows Media Player. (You should get version 9 or above, since it contains WMV3; if you have Windows 98 first edition or older, get the Windows Media Video 9 VCM package instead).
Both can be found here

I honestly doubt on a PC it’ll run with QuickTime Player at all.

If you’re on a Mac, you can try the Flip4Mac Windows Media component, which allows Windows Media files to play in QuickTime Player.
This may or may not work, since I don’t know if the component allows cross-container decoding.

Yet another try (for either PC or Mac) is VideoLan. It’s an excellent all-in-one player with its own internal filters and codecs, and decodes quite well independently of containers.

Finally if all else fails, you can try transcoding the audio and video stream back to a Windows Media container (extension wmv). I think the tool of choice for that is FFMPEG, but I think it’s command-line, and I haven’t worked with it before. You’ll likely find tips on how to do this on doom9.org.
