Hi all,

This is a three input cards (DVB-T, Composite and S-Video) and I am at the
moment struggling to capture from the Composite input, for example.

Attached are some v4l2-ctl outputs and gst-launch debug logs.

First thing I do is set input to composite:
v4l2-ctl -d 0 -i 1

Most naive attempt to get something is:
gst-launch-0.10  v4l2src ! queue ! xvimagesink

Which fails with (also log.0 attached):
gstv4l2object.c(2093): gst_v4l2_object_set_format (): /GstPipeline:pipeline0/GstV4l2Src:v4l2src0:
Call to S_FMT failed for YUYV @ 720x480: Invalid argument

Gstreamer is 0.10.32 and plugins-good are 0.10.27.

I tried messing around with specifying caps like:
v4l2src ! video/x-raw-yuv,format=YV12 ! queue ! xvimagesink

Which results in (log.yv12):
WARNING: erroneous pipeline: could not link v4l2src0 to queue0

If anyone has any hints on what is the problem it would be appreciated.

Thanks,

Tvrtko
