Hello,

As far as i know, H263 has three header mode that are mode A, B and C. The rfc2190 is recommend using mode A.

But, i can't find H263 header mode in VPU library and VPU document.

Could you let met know where can i find it?

From app team :

H263 header mode can be configured with the VPU ; please refer to

section 3.2.2.4 (EncHeaderParam) of the VPU API.

https://community.freescale.com/servlet/JiveServlet/download/317735-256858/VPU_API_RM_L3.0.35_1.1.0.pdf

There is no mention of modes but of profiles of which "h.263 - Profile 3" is mentioned (no A,B, or C) .

Have a great day,
Yuri

Hi Yuri,

Thanks for your response.

Could you give me more detailed information about your mentioned "h.263 - Profile 3"?

I couldn't find it in attached document.

And also, it's not found in the latest manual which is "Rev L3.10.17_1.0.0-ga, 05/2014".

In attached manual, the struct EncHeaderParam has five members.

typedef struct {

PhysicalAddress buf;

int size;

int headerType;

int userProfileLevelEnable;

int userProfileLevelIndication;

} EncHeaderParam;

Could you let me know which member relates with "h.263 - profiles"?

Regards,

Shin.
