The key problem is elsewhere. Maybe the omap3isp driver.
I can start the mplayer based camera-demo only once. If
I start a second time, it reports select-timeouts, i.e.
no video stream. To make it working for one call needs
a reboot :(

Yes, there is some mixup with YUVY and UYVY... Maybe in the
ISP.

Ah, yes.

I remember that the driver does not support interlaced mode.
But I am not even sure if the camera module can do that.

I have added it to letux-4.15-rc6.

BR and thanks,
