GStreamer + Hauppauge WinTV-HVR1120

[Paulo Paiva]

Hello all!

I have a Hauppauge WinTV-HVR1120 and the system where the card is
installed is openSUSE 11.3 (i586).

When I run the simple command to view what is going on in the /dev/video
I get the message:

$ gst-launch v4l2src device=/dev/video0 ! ffmpegcolorspace ! autovideosink
Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Device
'/dev/video0' cannot capture at 720x578
Additional debug info:
gstv4l2object.c(2093): gst_v4l2_object_set_format ():
/GstPipeline:pipeline0/GstV4l2Src:v4l2src0:
Call to S_FMT failed for YUYV @ 720x578: Invalid argument
Setting pipeline to NULL ...
Freeing pipeline ...

So I tried again passing some arguments:

$ gst-launch v4l2src device=/dev/video0 !
video/x-raw-yuv,width=352,height=288  ! ffmpegcolorspace ! autovideosink
Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Device
'/dev/video0' cannot capture at 352x288
Additional debug info:
gstv4l2object.c(2093): gst_v4l2_object_set_format ():
/GstPipeline:pipeline0/GstV4l2Src:v4l2src0:

Setting pipeline to NULL ...
Freeing pipeline ...

Some insight in what I'm doing wrong or not doing?

Regards & Thanks all for the attention!

Done some more work on this problem.
Installed the latest v4l2 version from git and also installed all
gstreamer from git but no improvement.

I ran $ gst-launch --gst-debug=v4l2:5 v4l2src device=/dev/video0 !  
video/x-raw-yuv,width=352,height=288 ! autovideosink 2>log

The log is in annex. What I understand from this log is that there are
lots of supported pixel formats but no frame size... How can I solve
this problem?

Regards!
