Video in Telegram has suddenly become mirrored.

[Richard Naismith]

Hi everyone. I've been using OBS for several years now, but I've never encountered a problem like this. I'm using the latest MAC version, 29.0.2, but suddenly, today when I share to Telegram from OBS the video picture is mirrored, the wrong way around. Anyone have any ideas how this could be happening, and what could be done to correct it. Thank you very much. Richard.

Don't know how it's happening, but if you right-click the source (does Mac have a right-click?) and select Transform, you can make it right:

That's more of a band-aid though, so when you find the real solution, probably in Telegram, you'll want to put OBS back how it was.
