    I need to stream video from my camera module to the local wifi network, but without using any displays (HDMI, etc).

    If I connect the HDMI to the udoo before booting, I can run the camera as usual:

    gst-launch-1.0 imxv4l2videosrc ! imxipuvideosink
    gst-launch-1.0 imxv4l2videosrc ! imxeglvivsink

    both work. I also have a c++ program that broadcasts the video over local wifi that works, and I can receive the stream through VLC on any other computer in the network.

    However, if I boot the udoo without any displays, connect to it via Serial MicroUSB, start a terminal session over the serial port, then try to run anything related to the camera, I get these error messages:

    udooer@udoo:/dev$ gst-launch-1.0 imxv4l2videosrc ! imxipuvideosink
    Setting pipeline to PAUSED ...
    [ 2393.693660] ERROR: unrecognized std! 0 (PAL=ff, NTSC=b000
    [ 2394.073835] ERROR: v4l2 capture: unsupported ioctrl!
    Pipeline is live and does not need PREROLL ...
    Setting pipeline to PLAYING ...
    New clock: GstSystemClock

    Obviously when SSH'd into it I won't be able to see the video in the terminal. However, running the rtsp server also does not work, which makes me think the camera module is not being set up if there is no display attached. I couldn't find any info about configuring the camera module through SSH.

    Anyone have any ideas?
