I think that V4L2 specification is changed from linux 3.1.0.
http://linuxtv.org/downloads/v4l-dvb-apis/hist-v4l2.html#id3107689
This is relate information?

thanks for the hint;
i'll try to investigate (but i first have to setup a machine with 3.1 :-))

@umlaeute

i think i fixed the problem in the current HEAD.

could you please try again and confirm?

@yukkeorg

thanks.

I tried compiling HEAD and depmod on Linux 3.1.2. then execute below command.
(version of GStreamer is 0.10.35, and /dev/video1 is v4l2loopback device)

$ gst-launch videotestsrc ! "video/x-raw-yuv,width=640,height=480,framerate=30/1" ! v4l2sink device=/dev/video1

I got below message.

ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstV4l2Sink:v4l2sink0: Failed getting controls attributes on device '/dev/video1'.
Additional debug info:
v4l2_calls.c(267): gst_v4l2_fill_lists (): /GstPipeline:pipeline0/GstV4l2Sink:v4l2sink0:
Failed querying control 9963776 on device '/dev/video1'. (25 - Inappropriate ioctl for device)

mmm... Do not working.
I think v4l2 plugin on Gstreamer is not working with updated V4L2 API???

@umlaeute

hmm, no; i definitely checked with gstreamer and a simplistic pipeline like "videotestsrc ! v4l2sink" did work. (i didn't even use a capsfilter).

just to doublecheck: are you sure that you loaded the correct v4l2loopback module (it should say 0.4.1 in the kernel logs)

@yukkeorg

Author

Sorry. I missed.
I loaded v42loopback 0.4.0 which complied on Linux 3.1.2 with v4l2loopback-dkms.
this is checked kernel log and found.
I removed v4l2loopback-dkms, and reinstalled manually 0.4.1. then it worked.

Thank you very much.
