Identify color representation(YUV/RGB) of video file or exr image

[Irfan5EBE]

Hi,

I am developing an AE plug-in and integrating it on Premiere Pro. One of the requirement is to identify the color profile of input video file, meaning if user imports a file or EXR image from Premiere Pro, the requirement is to identify whether imported file contains RGB or YUV representations. I am going through Premiere Pro and After Effects SDK developer guide but couldn't find any information.
Please let me know After Effects or Premiere Pro API's available to find RGB and YUV representations.
Thanks in advance.

AE effect plug-ins get buffers of pixels from the host; these buffers do not necessarily correspond to the format saved in any source (input video) files.
