AM62A7: Adding Preprocess Function into Gsttiovxisp Plugin

Yizhe Fan

Part Number: AM62A7

Tool/software:

Hi TI experts,

We're trying to develop some raw image preprocess algorithms to AM62A Gstreamer pipeline. And I noticed that there is a reserved preprocess API in "gsttiovxisp.c" and its father class "gsttiovxmiso.c".

So I write a preprocess function into "gsttiovxisp.c" in the screenshot below. I can also read the raw data in the READ map type.

But when I tried to map the memory with READWRITE mode, wrong info said that the memory data cannot be mapped with WRITE mode.

Could you please help out?

Best Regards,

Hello Yizhe,

Are you trying to solve the same problem stated in this query: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1412001/am62a7-how-to-apply-the-self-developed-gstreamer-plugin-before-the-tiovxisp-plugin?

Hi Jianzhong,

Yes. We try to develop some raw data algorithm and find out two ways, using preprocess API left in "gsttiovxisp.c" OR creating a new plugin by ourselves.

Best,

Hi Yizhe,

Creating a custom plugin is the preferred way. Please see update on the other thread.
