imxv4l2videosrc: imx6ul: Inappropriate ioctl for device #278

Closed bbilas closed 3 years ago

bbilas commented 3 years ago

Hello everyone, I'm trying to use gstreamer to take a jpeg snapshot from the ov5640 camera connected to the iMX6UL board but I'm getting the following errors:

I've checked the connections using oscilloscope and everything looks good.

GStreamer 1.16.2 gstreamer-imx 0.13.1

bbilas commented 3 years ago

The main problem was in the i.MX6S_CSI driver within the NXP linux kernel fork that was really buggy. In addition, there was missing support of YUYV pixel format in gstreamer-imx plugin that was being used by my camera sensor [1].
