See bug #164176 comment 16 for details.

For example, if you have a pipeline like this:

 .... ! ffmpegcolorspace ! video/x-raw-rgb ! ffmpegcolorspace ! ....

then the link between the two ffmpegcolorspace fixates to
video/x-raw-rgb,bpp=8,depth=8, which makes it looks like there's a chroma defect
somewhere in the pipeline, while it's just that there are only 2 bits per pixel
per colour ...

The same might happen with other elements than ffmpegcolorspace as well of
course if they support multiple bpp/depths.

(Just filed this dummy bug so it appears in the release notes, might have bitten
 others).

Cheers
