It definitely looks like a colorspace issue. gscam can only process
RGB triplets. I'd need a similar YUV camera to tell you the exact
$GSCAM_CONFIG to use, but you should be able to go from YUV->RGB
within the pipeline itself. You might simply need to move or repeat
the ffmpegcolorspace node closer to the color definition. Something
like:
GSCAM_CONFIG="v4l2src device=/dev/video1 ! videoscale !
ffmpegcolorspace ! video/x-raw-rgb ! identity name=ros ! jpegenc !
fakesink"
or
GSCAM_CONFIG="v4l2src device=/dev/video1 ! videoscale !
video/x-raw-yuv,width=320,height=240 ! ffmpegcolorspace !
video/x-raw-rgb ! identity name=ros ! jpegenc ! fakesink"
I've had to do something similar with a black and white camera. Let me
know if that works for you.
