Hi,

 

I work with the imx53 QSB and I tried to display a captured video signal gotten with an ADV7180 (using mxc_v4l2_tvin program test). I get the following error during  execution (command line mxc_v4l2_tvin.out -oh 768 -ow 1024) :

 

ERROR: v4l2 capture: mxc_v4l_dqueue timeout enc_counter 0

VIDIOC_DQBUF failed.

 

It seems the imx never get the end of frame interruption that is waited as output condition of this called (in modifying the cam->enc_counter value) :

 

wait_event_interruptible_timeout(cam->enc_queue,cam->enc_counter != 0, 10 * HZ)  //line 1269 from mxc_v4l2_capture.c


I don't find any information to solve this problem. Are there any suggestion?

 

I could provide log or other information if needed

 

Cordially

Cyril
