Filling zeros in frame buffer

titusstalin — Sat, 17 Dec 2016 06:17:17 GMT

Dear All,

How can I fill the zeros in frame buffer ?

Actually I'm getting some alignment issues in camera frame buffer, then I found that the alignment issue occurs if camera send lesser data than what I've requested.

Say for ex, I'm requesting 1478656bytes of data and if camera sends 1440000bytes of data, there issues comes.

So what I think, can we fill zeros for the rest of the space ?

Thanks for your support.

Regards,

Titus S.

Hello

I am afraid, no way to fill the rest of buffer by zeros in IPU. Application should

know frame size or clear buffers before using in software.

Have a great day,
Yuri
