GStreamer + Hauppauge WinTV-HVR1120

[Paulo Paiva]

Mallard you have lightened my day!

I did that and there it was the beautiful image from the tv card :D, 
just used -i 0 to select tv.
Now another problem arises :S

Doing: $ gst-launch v4l2src ! autovideosink
It works perfectly!

But if I want to encode it I am getting a green screen all funky :S
$ gst-launch v4l2src device=/dev/video0 ! 
video/x-raw-yuv,fourcc=YU12,width=352,height=288 ! ffmpegcolorspace ! 
queue ! videoscale ! x264enc tune=zerolatency bitrate=1050 
speed-preset=3 ! autovideosink

It has to do with the pixel format? x264 accepts raw yuv in planar 4:2:0 
correct? By doing fourcc=YU12 am I doing that?

Regards!
