Hi all,

since this discussion, more people have joined the effort and the
consensus became to start a new project instead of pushing to
edid-decode upstream.

The new project is at
https://gitlab.freedesktop.org/emersion/libdisplay-info
where we are currently discussing what the API should look like in the
issues and merge request comments, so there is essentially no code yet.

If the project gains enough traction, I expect it will be moved into a
non-personal namespace under fd.o to live a life of its own.


Thanks,
pq
