fview is an application to view and record data from uncompressed digital video cameras. The name ‘’fview’’ derives from “fly viewer” – the software was developed within the Dickinson Lab at Caltech to record movies of flies.
See the Gallery for some screenshots.
Fview has options which can be set via environment variables. These are:
Set to non-zero to direct all output to the console (linux) or to a pop-up window (Windows, Mac OS X). Otherwise, the default behavior of saving to fview.log.
If this is non-zero, it will cause FView to raise an exception and thus close noisily, if any of its plugins raise exceptions. Otherwise, the default behavior of warning about the exception and continuing without the plugin will be used.
Set to non-zero to disable use of OpenGL for image display. This will be slower and take more CPU time, but will avoid any potential bugs with the OpenGL side of things.
Set to the directory name in which to record movies. (This can also be set with the Menu option “File->set record Directory...”.)
fview currently only supports a single camera. Although the plugin structure and the camera interface are inherently multi-camera ready, fview itself has not been written to support capturing from multiple cameras simultaneously. Flydra, for example, makes use of multiple cameras using motmot.
