Videos Crash Applications

The video playback crashes the applications all the time. How to fix?

One common cause for this is that there may be several incompatible video-codecs in the same machine. This may happen when multiple FFMPEG libraries are installed on the same computer.

On Linux most installers should be able to detect and avoid such conflicts. In practice we have found that for example under Ubuntu, it is possible to install gstreamer-ffmpeg that conflicts with the FFMPEG library that MultiTouch is providing.

If the video problems are caused by conflicting libraries, then removing the offending libraries may help.

The problems can also be caused by bugs in the FFMPEG library, which are triggered by the video material you are using. To check against this you can try selecting different video encoding, with different parameters. The most reliable video encoding tends to be DivX video (aka mpeg4) with linear PCM audio in an AVI container.
