vp8 encoding from windows desktop

Hi,

Thanks for your replies. I'm using this pipeline, apparently defaults work
better, maybe it automatically calculates the best parmeters

gst-launch-1.0.exe dx9screencapsrc ! video/x-raw,framerate=25/1 ! queue !
videoconvert ! vp8enc ! webmmux ! (filesink | tcpsink)

I need it to be webm for displaying on a browser. Direct output on screen
works flawlessly, using direct dx9screencapsrc ! autovideosink. Quality is
neat.

Now it's just about optimizing this pipeline, taking into account that I
want to stream inside my local network. Meaning bandwidth is not a problem,
I want to avoid any compression in order to enhance speed.

Best regards
