New format proposal

[nobu-k]

{
  "format": "cvmat",
  "width": width,
  "height": height,
  "image": <blob>
}

The current tuples generated from video sources look ilke this. In raspivideo, it also wanted to output raw images and JPEGs. So, I defined the format like below:

{
  "format": "raw",
  "color_model": "rgb",
  "width": width,
  "height": height,
  "image": <blob>
}

Instead of "cvmat", I defined "raw" format containing raw pixel values in a layout specified by the "color_model" field. The "color_model" field is only provided when the format is "raw". "raw" + "bgr" is equivalent to the current "cvmat" format.

I think this is more general and flexible than using the term "cvmat". What do you think?

The "color_model" field is only provided when the format is "raw".

sounds great.

If an image format is "RAW" and "RGBA", then format is "raw" and color_model is "rgba" ? I agree when color_modelrepresents image binary style.

Yes. Even though not all plugins need to support wide variety of color models, having that field would be useful.
