x264enc encoding parameters

[Ian Davidson]

Thanks for your help guys.

I am stuck with the camera system I have, so I have added deinterlace 
and I think that the resulting video looks better.

I have added the deinterlace as shown below - is that the best place?

v4l2src ! queue ! videorate ! videoscale ! 
video/x-raw,format=(string)I420,width=720,height=576,framerate=(fraction)25/1 
! queue ! videoconvert ! *deinterlace **! videoconvert* ! x264enc ! 
mp4mux ! filesink location=foo/bar
