Interlaced output modes
Created by: ElkMonster
Hi,
i just wanted to report that there's a need for interlaced output mode support. Interlaced modes are currently skipped (per https://github.com/swaywm/wlroots/pull/1382, as a solution to https://github.com/swaywm/sway/issues/3167). In the commit, the author says: "a better solution could be made if there's a need to".
My use case is rather special, so I'd understand if my request should be declined. Here it is:
The company I work for creates content for various TV stations around the world. Some TV stations require very specific ways of content delivery. In this particular case, we have to provide a PC that provides the content via SDI (Serial Digital Interface) at 1080i50, using an HDMI to SDI adapter. We're using Sway on that machine because it allows us to easily control the output window exactly as we want to (activate fullscreen, move to a specific display, hide mouse cursor).
For now, I've created a patched version of wlroots that simply skips progressive modes instead of interlaced modes, and installed it on the concerned box. We'll be able to live with that hack because that box will probably rarely be touched, however, I'd be happy to be able to use upstream wlroots in the future.
Thanks for your consideration Sascha
