TDA4VM: Is it possible to save image as RGB data?

Zs lei

Part Number: TDA4VM

Hi TI Experts,

As FCP block description, image data can be output as RGB data. Is it possible to save image data to RGB format file? E.g., BMP format.

If yes, how to do it? I use multi-cam app as debuging app.

Hi Zhichen,

RGB output from VISS is in planar format, so it cannot be saved as BMP, as BMP is typically interleaved format.

Hi Brijesh,

Thanks for your reply. Is it possible to dump each rgb channel data individually?

Hi Zhishen,

Yes, in OpenVX, you can create separate buffers for red, blue and green color components, setup the VISS for these outputs and then can dump them individually.

Hi Zhichen,

Unfortunately, there isn't any usecase level example, because it is not used anywhere. You can probably refer to standalone example in tiovx\kernels_j7\hwa\test\test_vpac_viss.c file.
