Hi I'm on Windows trying to stream my screen to webm. I'm using this for
testing my encoding:

$ gst-launch-1.0.exe dx9screencapsrc x=0 y=0 width=800 height=600 !
video/x-raw,framerate=25/1 ! videoconvert ! queue ! vp8enc end-usage=vbr
target-bitrate=512000 buffer-size=10000 buffer-initial-size=6000
buffer-optimal-size=8000 keyframe-mode=1 keyframe-max-dist=1
max-intra-bitrate=1 ! webmmux streamable=true ! filesink

I'm getting a very noisy result. Maybe it is because I'm writing to disk.
But I'm quite certain I'm doing something wrong. What I want is to have the
most balanced quality/speed ratio..

The vp8enc parameters are supposed to help me achieve this. My machine
specs are:

Intel Xeon E5620 @ 2.40GHz (16 CPUs) ~2.40GHz
16384MB RAM

NVIDIA Quadro FX 3800

Any information is appreciated!

Thanks a log gstreamer-devs!
