v4l2src does not support interlace video

[Baby Octopus]

Hi,

I'm trying to capture 1080i at 50 from a v4l2 device named "device0". I'm
unable to capture interlaced content from the following pipeline but it
gives negotiation issue but works fine if I make it progressive

*gst-launch-1.0 v4l2src !
video/x-raw,width=1920,height=1080,interlace-mode=interleaved ! fakesink*

ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Internal
data flow error.
Additional debug info:
gstbasesrc.c(2913): gst_base_src_loop ():
/GstPipeline:pipeline0/GstV4l2Src:v4l2src0:
streaming task paused, reason not-negotiated (-4)


Does v4l2src not support interlaced capture?

~BO
