RTOS/TDA2: Dynamic changes for VPE

Surendar V B

Part Number: TDA2

Tool/software: TI-RTOS

Hi Everyone ,

We are working on requirement to dynamically zoom in particular region of the output we are capturing.

we have a VPE link in TDA2 which will perform the cropping and resizing , I like to know whether it is possible to change the crop parameters dynamically on runtime for VPE link .

If that is possible , kindly suggest me if there are another ways to crop dynamically without rebooting .

Hi Surendar,

At which rate do you want to change the parameters?

Hi Brijesh ,

I could not understand what you mentioned by "rate" , is it FPS or is it something else . Can you please elaborate on that.

Surendar,

I meant, do you want to change it on every frame submission?

Hi Surendar,

ok, i would suggest you to have a look into the API VpeLink_drvUpdateInputRtPrm in VPE link. This will give idea for how you could change the VPE crop parameters per frame.
