Is there any modules in dm365 can deal with it?

If i programme a funtion to do the conversion in manual, is there any problem that may reduce the real-time performance?

Can anyone give me some help or advise?

Thanks in advance.

Hi,

I can capture YUV420,  just using DVSDK  "encode"  sample, also using TVP5146.

However you can also use DM36x HW resizer for color conversion.

Marko.

Hi Marko,

I have the EUCDK source code. How to build the DVSDK  "encode"  sample? It depends on DMAI.

But when I build DMAI. It fell down on this:

How can I solve it?

And as your suggest I have read through VPFE User's Guide.pdf, found DM36x HW resizer for color conversion.

It's just what I want. But I don not know how to use it. Can you give me some indicate or some sample code.

Appretiate your help very much.

Regards,

Lei

Hi Lei,

I don't know how to build DVSDK examples with EUCDK kit, probably you should export dvsdk path.

However you rather move to the latest TI DVSDK 4.01.00.09.

software-dl.ti.com/.../dvsdk

Install it and simply follow build instructions in dvsdk/docs/TMS320DM365_Software_developers_Guide.pdf (from page 19).

You have resize demos in dvsdk4/dmai/packages/ti/sdo/dmai/apps/ video_loopback_resize,

also look at dmai resize.c,

and in dvsdk4/psp/linux-driver-examples-psp03.01.01.38/imp-prev-rsz/ (several demos)

You have 2 resizer HW modes:

1. one-the-fly (chained), where resizer is chained to capture engine; you can get  at most 2 different resolutions out 1 from RSZA and 1 from RSZB;  

 for only color conversion, just set the same input and output buffers, then only set appropriate output color format for output1.

2. single-shot : first you get captured frame, then you can take as many resizes you want, this is when you need more the 2 output resolutions.

Chained mode is faster.

When you resize  from YUV422 you need only 1 resize operation (this is your case YUV422 to YUV420),

but when you resize from YUV420, you need 2 cycles : first resize Y plane, and in the next cycle you resize UV plane.

Also there is a lot of  of DM36x resize discussions at  e2e.ti.com forums.

Regards,

Marko.

Hi Marko,

I succeeded in capturing V4L2_PIX_FMT_NV12 after use resizer HW mode on-the-fly. And encode also works well.

I used V4L2_MEMORY_MMAP in my application whereas the imp-prev-rsz sample code used V4L2_MEMORY_USERPTR. I wonder whether the difference would cause any problem. Because I found that the sample allocated the buffers mutiple of  32 and 4096. I seems have saw the buffer constraint in this usage described somewhere but can not find it again.

Thanks for being so helpful.

Regards,

Lei
