I am trying to stream from the ov5640 mipi module but there is always error in the gstreamer ("Pipeline doesn't want to pause."
Reduced to the simplest pipeline, it is:
root@imx6qdlsolo:/root# gst-launch-1.0 imxv4l2src ! imxv4l2sink
====== IMXV4L2SRC: 4.0.8 build on Dec 4 2015 22:06:47. ======
====== IMXV4L2SINK: 4.0.8 build on Dec 4 2015 22:06:47. ======
Setting pipeline to PAUSED ...
display(/dev/fb0) resolution is (1024x768).
ERROR: Pipeline doesn't want to pause.
Setting pipeline to NULL ...
Freeing pipeline ...
The camera module as such seems to be working OK, at least I can get raw YUV buffer and convert it to an image:
/unit_tests/mxc_v4l2_capture.out -iw 640 -ih 480 -ow 640 -oh 480 -m 0 -i 1 -r 0 -c 1 -fr 30 -d /dev/video1 /root/test.yuv
then using imagemagick (on another machine but could also be done on the sabresd board):
convert -size 640x480 -depth 8 -colorspace RGB test.yuv test.jpg
The system is as follows:

Any clue? What could have gone wrong?
