Upgrade from Dizzy to Fido breaks video stream

Question asked by chrgrff1 on Sep 15, 2015
Latest reply on Sep 28, 2015 by chrgrff1

We've got a custom TVP5147 driver that worked under Dizzy. We recently upgraded to Fido, and I'm getting mxc_v4l_dqueue timeouts now.

 

I diffed the kernel drivers in drivers/media/platform/mxc/capture and it doesn't look like there were any API changes to the ADV7180 or OV5640 drivers between Dizzy and Fido, so I'd hoped our driver would just continue to work.

 

I've attached the kernel log from a simple "gst-launch-1.0 imxv4l2src ! imxv4l2sink" to demonstrate the timeouts. I'm hoping there's a known upgrade path for me to take or that someone can point me in the right direction to debug this.

 

Thank you!
