AirPlay uses a fixed latency of 2 seconds, so 500ms is not bad. Either way it's not a technical accomplishment/failure, the longer the latency the longer you can put up with your WiFi breaking without having your audio blip.

500ms should be enough that you can roam between multiple APs without the audio stream being interrupted. If you're on hard-wired ethernet you should just be able to modify the snapcast source code to reduce it to whatever you want (10ms should be fine).

Tbh, I feel like this was a genius move by Apple. AirPlay’s 2 second delay gives plenty of time for all devices to sync up and they simply build it in to the AV playback so that videos are perfectly synced to audio as well.

However, without that source-side adjustment: 500ms is a lot. Especially for video.

Yes, snapcast is really designed for audio streaming. For video it's not going to work (but surely for video cases you want something to stream both audio and video?).
