How to scale video image and graphic simultaneously

Marcus,

GRPX内部带了缩放模块。但video图像需要用SC来缩放。

Hi Chris:

I appreciate your reply!

If I do not misunderstand what you mean, I can not scale the video image and graphic simultaneously,right?

I must use gprx and SC to scale graphic and video image one by one,right?

I see there is SC parameter in multich_progressive_8d1_vcap_venc_vdec_vdis.c.

So, this SC link only work for video,right?

Because, we use multich_progressive_4d1_vcap_venc_vdec_vdis.c to develop our system, so there is no SC parameter.

I do not know why SC parameter is used by 8CH and 16CH.

Could you tell me the reason?

Best regards,

Marcus

Hi Chris:

I follow your suggestion and add scalar link to down scalar, but it only affect video.

What I mean is that the graphic remains same size.

Is there another way that can scale the video image and graphic simultaneously?

Could you help me, I have tried to solve this issue for couple weeks?

Best regards,

Marcus 

Hi there

For me ,i usually scale the image using an image processing  control.It can scale,crop image well.But i've never tried to scale video image.

I think there must be some third party program which can scale video image directly.You can have a try.
