Hello,
I'm having a strange issue with my i.MX6 board.
My device is a Toradex Colibri i.MX6 DL, on a custom carrier board. The camera driver have been modified for our camers. Everything works fine (record, replay, live...).
When I type :
root@colibri-imx6:~# v4l2-ctl --all
Driver Info (not using libv4l2):

The driver recognize the camera, and the pixel format is YUYV.
But when I launch a simple gstreamer pipeline :
root@colibri-imx6:~# gst-launch-1.0 imxv4l2videosrc ! imxg2dvideosink -v
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
/GstPipeline:pipeline0/GstImxV4l2VideoSrc:imxv4l2videosrc0.GstPad:src: caps = "video/x-raw\,\ format\=\(string\)YUY2\,\ width\=\(int\)1920\,\ height\=\(int\)1080\,\ interlace-mode\=\(string\)progressive\,\ framerate\=\(fraction\)30/1\,\ pixel-aspect-ratio\=\(fraction\)1/1"
/GstPipeline:pipeline0/GstImxG2DVideoSink:imxg2dvideosink0.GstPad:sink: caps = "video/x-raw\,\ format\=\(string\)YUY2\,\ width\=\(int\)1920\,\ height\=\(int\)1080\,\ interlace-mode\=\(string\)progressive\,\ framerate\=\(fraction\)30/1\,\ pixel-aspect-ratio\=\(fraction\)1/1"
Setting pipeline to PLAYING ...
New clock: GstSystemClock
Why my format change from YUYV to YUY2? When I force with caps, it does not work at all.
It bothers me because I need to encode in h264, and only the videoconvert plugin converts from YUY2 to I420. I would like to use an hardware plugin (g2d, ipu...).
