okay so picture this: you're deep in the Kernel API Manual (yeah, the section 9 one, the fancy one) and you've got a video queue that wants to stop streaming. This little guy is the one who updates the whole encoding/decoding session state when that stop is requested. That's it, that's the function, and honestly? iconic behaviour. 🎀
