How to converte RGB888 into YUV422 using VIP csc?

Yes, it is possible to convert RGB888 to YUV422 in DM385 VIP port. What error are you seeing? Can you provide your vip create time parameters?
Also which rdk and its release that you are using?Rgds,Brijesh

Thanks for your answer.
Here is my error.

Hello Yang,
Do you want to have YUV output or RGB? The above code sets RGB input and output.
Anyways, Capture list should never hang, it should lik it is trying to something which it should not do. Looks like either it is trying to program scalar coefficients or may be done discrete sync start up sequence. Do you happen to have source code of the hdvpss driver? we could put some debug prints and check where it hangs.

Hi, Brijesh Jadav.

1.

Sorry for my careless, I was then trying to figure it out.  So I've change the parameters .

I want to get RGB input and YUV output.

Generally speaking , I want to capture the RGB888 date from the VIP port ,and display it .

According to my research these days ,I find that it could be done weather through VIP csc to converte RGB888 into YUV inside the VIP block,

or use the GRPX block to display the RGB888 date without change it . I got it from the blow picture.

But     I   have not seen a example of GRPX block .  So I  want to converte RGB888 to YUV   through VIP csc block.

Now , we haven't  prepare the  external device to provide the RBG source. I want to get DM385 just ready to do that. 

2.

I have hdvpss drivers ,then I would try .

Regards,

yang

really thanks. It's ok now .
But I wonder wheather this API's miss will influence the following work it need to do ?
And what does this api do ?
Regards,

yang

Hello Yang,
This API is not required for the DM385, so it is ok to comment it out for your use.
Please note it is better to check code the sensor connected and configured and VIP is really capturing valid frames.
