[RFC] add Bayer fourccs
by Peter Ross 22 Feb '14

22 Feb '14

--- Hi. Here is my stab at assigning fourcs for Bayer pixel formats. I've used character 0xBA to identify Bayer formats, followed by the top component order and bit-depth. A 7-bit ASCII value would probably be better.

NUT version bump
by Luca Barbato 15 May '13

15 May '13

While updating my notes I noticed we are using version 3 to generate something that does not contain the main_flags. (Yes somewhere I have patches to support BROADCAST_MODE and I'm thinking about introducing an unseekable PIPE_MODE dropping syncpoints completely) I suggest to hold either bump to 4 for the version exposing the main_flags and use version 5 for futher changes or lump together main_flags and frame specific data support. lu
