Query on SDI Video Capture using Davinci DM6467

Other Parts Discussed in Thread: TVP7002

Hi ,

 

Hope you doing well. I have query on SDI Video capture using our Davinci DM6467 processor.

 

H/W Setup :

 

Our setup looks same like below,

 

Davinci DM6467

(VPIF Bus )

SDI Receiver GS2970

SDI Receiver                                                       Digital Output

                                                                                                                                                                RGB Parameters                                                                              

                                                                                CLK                                                                                        

 

 

 

 


S/W Details: Application to calculate RGB --------------à RX_v4l2.C-------------àDavinciHD_capture.C

 

 

Am trying to capture the video using video device /dev/video0 and using VIDIOC_G_INPUT or VIDIOC_S_INPUT to capture the data but am getting error as resource is not temporarily available while de-queues a captured buffer from driver.

 

But am able to probe the data’s and clock in the H/W. I have also attached the log while doing this test and also the function we use fro testing RGB Function.

 

Please request your help on this issue. As this activity being long time pending for us.

 

Note : We have followed the same procedure for capturing the component video using TVP7002 , instead of tvp7002 we use Rx_V4l2 driver for sdi receiver.
