TDA4VM: Reduce image resolution.

qian yue

Part Number: TDA4VM

Hi，

We are currently using 1280* 720@30fps Camera type, output YUV422@8bit Type image data.
May I ask how to reduce the resolution of the camera's image and thus reduce CPU usage?

SDK : 08.06.00.12 app_multi_cam_codec

Hi,

you can use MSC scalar to downscale the image resolution and then use codec to reduce CPU usage.

Hi Brijesh,

May I ask if you can provide relevant examples? Or can you help me point out examples of using relevant interfaces in SDKs?

Can the image resolution of the capture node be reduced?

Well, not the exact example, but you can refer to scalar usage in many of the other examples. Like single camera application uses scalar node, tivxVpacMscScaleNode, to reduce the input image resolution to 1080p resolution.

OK, I will refer to "tivxVpacMscScaleNode" for related applications.Thank you!
