Hi TI:

We have two cameras on DM388.

1. 5M CMOS sensor (MIPI)

2. VGA Camera (YUV)

We hope to display the two camera video content in LCM panel at the same time.

After querying document, we found DM388 has support PIP function. (Picture in Picture)

Can you tell us how to use it?

Thanks

Reference:

The COMP module has four independently controlled blenders (compositors): three for HD output and one
for SD output. Each HD blender can take up to five input layers (two videos and three graphics) to
generate one composite output layer. The SD blender can take up to four input layers (one video and
three graphics) to generate one composite output layer.

1. Video-0 (HD main video/ HD main video CIT/ SD video)
2. Video-1 (HD pip video; Not available for SD output)
3. Grpx-0
4. Grpx-1
5. Grpx-2

Hi DakHou,

Have you checked IPNC uses cases in ipnc_rdk\ipnc_mcfw\mcfw\src_linux\mcfw_api\usecases?
This example multich_captMctnfDisp.c might help you :)

Thanks

Hi Ravikiran:

Thanks you very much.

It works fine~

Can I ask one more question?

Because I need to enable / disable PIP dynamically.

Do you know how to do it?

Thanks

Hi Ravikiran:
We found how to switch layout already.
Thanks you very much.

We can use SYSTEM_SW_MS_LINK_CMD_SWITCH_LAYOUT to switch layout.
