@wakest Perhaps should come as no surprise but I'm still working out the details. The amount of space allocated for this type of cache, the duration for which it will be stored, and other details, such as various rate limits and the option to disable this feature entirely, will be configurable by the instance admin via the web admin interface. And yeah, this thing is not Tusky-specific in any way. Most of the MastoAPI clients that are able to play videos should also be able to play livestreams, although since practically none of them was actually designed and tested for this case, some of them might have a bad time. I don't have the means to check them all, so I'll have to rely solely on reports from the hypothetical future community.
