DM8148 IPNC: How to process 960x540 frame in DSP?

Hi, 

This can be a general question for any frame size other than 320x240 on the DSP side. 

So if I want to process the frame on the size of 960x540, or even 1080p, what should I do? 

The following options are in my mind: 

1. vaLink: I have successful experience on replacing DMVAL with my own algorithm. However, I am struggling in getting a different frame size to work. 

2. SWOSD

3. Create a new link

Please let me know if you have any input or similar experience. Thanks a lot.

    I think option (1) should work. Can you please give more details on what problem you face when you try to increase frame size?

    Regards

    Hello,

    Please note that the VA alogrithms supported on DSP run on maximum resolution of 320x240.

    You will need to resize the your inputs to this size via scalar (as in usecase example)

    Also, if you trying to run your algorithm with increased frame size using DMVAL API, please ensure there any no limitcheck for 320x240 for width and hieght at the inerface level.

    ALso, are you facing memory alooc issue? please share log and more details of the issue?

    Regards,

    Raghu
