Hi Chris,

gst-launch videotestsrc ! v4l2sink

to work as there's no /dev/video1 ! Does anyone know where I can find 
instructions on how to get v4l2 working under Ubuntu 12.04 for a radeon HD 5450 
card? Google has not been my friend ;-)


/dev/video1 is created when you have an actual video input like a video decoder or camera or UVC camera and it would be used with v4l2src (or in the case of i.MX6 CSI, mfw_v4lsrc).

videotestsrc should not need a video input device to work though as it is creates its own video data. What is the error you are seeing?

What is your setup?  Board? Yocto version?  Yocto image?

John
