That's a weird error really. If you get it again, please send logs from Air Video Server HD (Create Archive from Logs) to support(at)inmethod.com . Thanks
No problem, I'll do it if it happens again. Everything seems fine now. I wonder if it was starting to play before it was ready - y'know how the iOS client has "loading details" when you go into a new folder? Well, when I went into the folder I wanted to play from, there were no thumbnails generated yet; iOS clients won't let you play til it's downloaded the stuff it needs, but the Apple TV client started playing immediately - I wonder if it's related to that. Essentially, perhaps there *was* no stream to play.
I've no idea what I'm talking about when it comes to video streaming, but given the sequence of events and the slight difference in behaviour in iOS clients vs the tvOS client, I wonder if that's it.
The sequence in iOS is: go into new folder, each file says "loading details" - there is no thumbnail etc at this stage, and you can't tap on any video to play them. You have to wait til it's "loaded details" for the file you want to play. If you tap on a file while it's displaying "loading details", you simply get no response.
In tvOS, the sequence was: go into new folder, there's no "loading details" because the files were laid out in a grid; no thumbnails, cos this was the first time the client had touched the folder. I tapped on the first file in the list and got the above error message. A few seconds later I reversed back into the folder from the 'play' screen (with the error on it), and all the thumbnails were there and every video played perfectly.
So, hopefully it's just that I played too soon - maybe for UX purposes it would be good for there to be a delay built into the client to stop people getting errors if they're as impatient as I was :-)
