From Cedric Pinson, "Here an update of the directshow plugin. It fixes issues with

Browse Source 
synchronization, improve capture device support.

here how to use it to display a capture device:

osg::Options* options = new osg::Options;
options->setPluginStringData("captureWantedWidth", "800");
options->setPluginStringData("captureWantedHeight", "600");
options->setPluginStringData("captureWantedFps", "30");
options->setPluginStringData("captureVideoDevice", "USB Video Device" );
options->setPluginStringData("captureSoundDevice", "");
then
osgDB::readImageFile("capture.directshow", options)
you can use a graphedit application to list devices available in
directshow.


for classic avi file you just need to do a
osgDB::readImageFile("file.avi.directshow");
You will need of course to install the codec needed by directshow to
read the avi files.

I recommand this tool http://avicodec.duby.info/, that check which
video/sound codec is needed to play an avi file.


You can test it with the osgmovie example.
