While implementing this, I run into a couple of questions:
1) what type should I associate with the bayer encoded images?
It doesn't really fit any of the types mentioned on
Should I define a new mimetype?
How about using a generic mimetype (like "video/x-raw") and
specifying a "format" property that contains the fourcc code
as reported by v4l2?
2) is it OK if the chain function of a plugin simply collects
until it has received a full frame and then pushes a complete
converted image out? (instead of doing it in smaller pieces)
All the best,
