DM816x: Queries for RGB888 capture-display, upscaling and RGB<->YUV conversion

Hi,

I want to capture RGB888 data using V4L2 and want to upscale the video up to 5x (max. 1920x1200). I want the data to be displayed as RGB888 only.

I/P: RGB888

cropping & up-scaling up to 5x

O/P: RGB888

Can someone please confirm following ?

- As I understand, I can't use graphics pipeline, since it supports only 4x up-scaling.

- Since crop/scale operation can be done only on YUV420 data. If I use V4L2 to capture the video and get RGB888 data, which hardware component should I use for RGB to YUV420 conversion ? Is Omx component available for this operation ?

- If I use Omx VFCC component instead of V4L2 based capture, does it support dual output (RGB888 and YUV420) for RGB888 i/p ?

- Is there any hardware component for YUV to RGB888 conversion in order to display RGB888 data on V4L2 display driver ?

Thanks in advance.

Regards,
Sweta

    Hi Sweta,

    1. Since crop/scale operation can be done only on YUV420 data. If I use V4L2 to capture the video and get RGB888 data, which hardware component should I use for RGB to YUV420 conversion ? Is Omx component available for this operation ?

    [Hardik] This is not supported as of now.

    [Hardik] This is supported by FVID2 Drivers, but at Omx level  this is not tested.

    [Hardik] In hardware yes, software support No
