Summary: [ffmpegcolorspace] RGB fixation issue (needlessly
fixates to 8 bpp)
Product: GStreamer
Version: 0.8.x
Platform: Other
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: gst-plugins
AssignedTo: gstreamer-bugs at lists.sourceforge.net
ReportedBy: t.i.m at zen.co.uk

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
