At about the same time the way URLs sent to the standard webpage-based IPlayer were parsed (recognised) changed, so that simple addresses which had worked for years, failed. I've managed to find the 'new' URLs for the same pages of material, and *they* took a day or so to fully work. This may be a side effect of some deckchair shuffling for 'Zounds!"
I'm currently trying to find out more about this. But so far as I can tell thus far, the web-browser based iPlayer interface should continue, and will still offer 320k aac.
Can't mobile devices use that and get the 320k aac? i.e. do that have web browsers that will then let them listen to the streams via the webpage links?
I don't have any such devices, only an ancient *phone*, so can't check directly. But all being well, I'll learn more soon.
I'm wondering if part of the problems here is that people simply don't know what is available, how, so then don't take up the best audio options because no-one has explained that they exist, how to get them, and why it matters.
