why FVID_dequeue failed?

zhao yanjie

I found if the input mode of VPFE is set as FVID_FIELD_MODE,there is no error.But if it is set as FVID_FRAME_MODE,the FVID_dequeue will fail.And I am sure the input-data stream is FRAME_MODE.

why?Could you help me how to correct it?

Zhao,

Can you please provide me some more information,

1. Which version of the BIOS PSP are you using?

2. Which board are you using? Is it EVM or the custom board?

3. If you are using the BIOS PSP, the are you able to execute the sample application which comes with the PSP?

Thanks and Regards,

Sandeep K

Zhao,

Sorry for the delayed response.

Which sample application are you using?

What kind of error are you getting?

Is FVID_dequeue() coming back with the invalid buffer?

Thanks and Regards,
