libv4l2: error getting pixformat: Invalid argument

[Lawrence Anthony]

Hi I am a newbie with gstream and am having issues with the following:

Server:

gst-launch -v --gst-debug-level=3 decklinksrc mode=11 connection=1 ! v4l2sink device=/dev/video2


Client:

gst-launch v4l2src device=/dev/video2 ! autovideosink


Setting pipeline to PAUSED ...
libv4l2: error getting pixformat: Invalid argument
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Could not negotiate format
Additional debug info:
gstbasesrc.c(2830): gst_base_src_start (): /GstPipeline:pipeline0/GstV4l2Src:v4l2src0:
Check your filtered caps, if any
Setting pipeline to NULL ...
Freeing pipeline ...


Any help is appreciated!

As I continue to educate myself. I have found this is the debug logs

 INFO  v4l2 gstv4l2object.c:1105:gst_v4l2_object_fill_format_list:<v4l2src0> got 0 format(s):

From what I can tell I should have at least one playback format. Am I missing something easy here?

I am able to playback using 

gst-launch decklinksrc mode=11 ! ffmpegcolorspace ! ximagesink

1) Take a look at the log at DEBUG level.
2) Check the output of v4l-info
