Linux/AM5728: Video input format

Part Number: AM5728

Tool/software: Linux

Hello

Our Video circuit : 

Component Video  => ADV7403 => AM5728 (vin3a of VIP2)

We have configure ADV7403 to YUV 16 bit ( YVYU).

Based on media-bus-format.h (/include/uapi/linux/media-bus-format.h) and videodev2.h (/include/uapi/linux/videodev2.h) we should use :

MEDIA_BUS_FMT_YVYU8_1X16  and V4L2_PIX_FMT_YVYU for our configuration.

But in /driver/media/platform/ti-vpe/vip.c we see this in line 248 : /* V4L2 currently only defines one 16 bit variant */

which is for RAW16, not YVYU16.

Questions :

1_ Does V4L2 and VIP supports 16 bit YVYU or not? how we can add this input format ?

2_ Where we should set input format in media decoder chip driver (please you explain it based on ADV7180 driver)

3_ Should the video input format be set to decoder IC driver only or need changes in vip.c, vpe.c, ...?

Best Regards.

I'm still waiting.

there is no anyone to solve my question?!!!!!

Hi Mike,

Thank you for your reply.

OK. Now we want to configure VIP2 input format to UYVY 8bit.

So where we should select port, for example vin3a-d0~vin3a-d7   or   vin3a-d8~vin3a-d15 ?

In u-boot, /board/ti/am57xx/mux_data.h vin3a has set as 32 bit input port.

Best Regards.
