A lot of cameras will list maximum time before shutting off as 29 minutes, 59 seconds. This isn't neccessarily because of overheating issues but (I think) to avoid falling on the wrong side of some tax/duty differences between camcorders and stills cameras.
As an example, on my home setup I use a Canon R5 for video calls (way overpowered for this task but I have it for stills photography). This lists maximum recording time as 29:59. However it doesn't limit the amount of time it can be switched on and outputting via HDMI and I've used it for calls of 3+ hours without any issue (with an AC battery adapter).

That's for recording to memory card, not for the HDMI feed.
