View Full Version : Unsupported video formats

01-23-2013, 09:12 AM
Hi there.

I am trying to use a very small video as a texture and it seems that most of the file formats are not supported by Vizard, although the documentation says "Vizard supports any video file for which your system has a codec."

Besides avi and mpg the other common formats give the following errors:
- mp4, mkv
ValueError: Unrecognized file extension: MP4 or MKV
- mov
** ERROR: Failed to construct graph (Cannot play back the file. The format is not supported.)
** ERROR: Failed to load video: 'textures/fire.mov'

No need to say that I can play those videos normally in WMP, QuickTime, and VLC.

What kind of machine and OS are you running on? Can you attach a small sample file that runs in WMP but not in Vizard?

I am running Windows 7, 64-bit.
I attach two of the files I have been trying that give me those error messages. They both play fine in WMP.

In Windows Vista/7, WMP uses Media Foundation instead of DirectShow for several media related tasks. Some file formats that are played using Media Foundation are mp4 and mov.

Vizard uses DirectShow so you'll need the DirectShow filters. I installed the k-lite codec pack mega and then had no problem playing those files.
