Strange Pixels when preview is small for Directshow TV
Posted: 13 May 2008 22:15
When I shrink the output window smaller than the Direct show size I get weird "static" Attached is an example.
I am using the activeX cointrol but this happens in the player too. Should I do something different when viewing> i.e. Set the video output size first?
Attached is the javascript used to render the above file
