How to get the frames statistics from MIPI camera ?

titusstalin — Mon, 06 Feb 2017 06:41:15 GMT

Dear All,

I want to get the below details from my OV5640 MIPI camera while stream ON/OFF.

1) Current frame rate (I think, we can get this using VIDIOC_G_PARAM ioctl call)

2) Number of Packets with CRC errors.

3) Number of frames dropped due to underrun error (or any other errors)

4) Frames count (no of frames received)

5) Frames incomplete (no of frames which are incomplete)

Can you please tell me how can I get this details from mxc MIPI driver ?

Thanks for your support.
