reprogramming source

[James Linder]

G’day

I have a capture card (sensoray 2263)

After setting the output to 1080 vlc and mplayer ‘reset’ the output to 720x576
Running mplayer like this
mplayer tv:///dev/video2 -geometry 1920x1080 keeps the card output at 1080 (but won’t set a 720x576 card to 1080)

Running my test pipeline

gst-launch-1.0 v4l2src name=source device=/dev/video2 ! queue ! videoscale ! video/x-raw,width=1920,height=1080 ! videoconvert ! xvimagesink force-aspect-ratio=false name=sink1

results in 720x576 weather or not I set the card to 1080.

Can anybody tell me how to tell gstreamer to ask/tell the card to output 1080?

Thanks
James
