Gstreamer v4l2src and dmai on OMAP l138

Hello,

i triend to run the following gstreamer pipeline on target omap-l138:

gst-launch gst-launch v4l2src always_copy=FALSE ! video/x-raw-yuv ! ffmpegcolorspace ! fbdevsink

But there i get the following error:

ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Cannot identify.
Additional debug info:                                                          
v4l2_calls.c(493): gst_v4l2_open (): /GstPipeline:pipeline0/GstV4l2Src:v4l2src0:
system error: No such file or directory                                         
Setting pipeline to NULL ...

After i'm glad if you could tell me if is possible to build DMAI plugins on this target!

Thank you in advance!
