Re: is it possible with npanpi plug-in to catch streaming ?

There's nothing in NPAPI that would allow you to capture the video or
audio output of another plugin. However, if you know how to write a
native application that captures video and audio from another already-
running process you could do the same in an NPAPI plugin. You'd also
need a browser extension in order to inject your plugin when Flash was
present though.
