The range for partial recording of the rotation screen is incorrect

[tkna91]

This phenomenon occurred to me as well.

It also recorded the wrong part of the screen when passing the geometry via slurp. For my 90 degrees rotated screen when I wanted to record something on the bottom left, it recorded something on the top left instead.

My vertical monitor recordings are not rotated correctly even when recording the entire screen. I'm using the Hyprland portal but OBS works fine.

Did you find a solution for this?

I have tested sway and wayfire with 90 rotation - both work with grim or wf-recorder using slurp. If you are having this issue, can you try with wf-recorder --no-dmabuf to see if it makes a difference?

@soreau The recording range appears to be accurate, although there is a problem with rotational recording.

@tkna91 Hi, thanks for your input. If I understand correctly, you're saying that the recorded region is correct on 90/270 transformed outputs but the resulting video is transposed? If so, can you see if this pull request fixes it?

@soreau

If so, can you see if this pull request fixes it?

Sorry, I am not sure how to do that and am looking into it.

[tkna91]

@soreau Sorry if I am doing something wrong. Apparently it doesn't seem to work.

I built it this way.
