[gst-devel] v4l2sink with USB webcam gadget

[Will Kelleher]

Hi everyone,

I've been trying to use my TI Davinci hardware as a USB webcam gadget.
 I backported the webcam module to the 2.6.32 kernel and I can
compile/load it successfully.  This module creates a v4l2 output
device that can accept YUY2 and MJPEG formats.

When I run

gst-launch videotestsrc ! v4l2sink device=/dev/video1

I get

"ERROR: from element
/GstPipeline:pipeline0/GstVideoTestSrc:videotestsrc0: Could not
negotiate format"

I've tried a variety of other pipelines but they all produce the same error.

Does anyone have experience with sending output to this particular
module (g_webcam)?  Am I doing something obviously wrong?

Thanks,
