Everything that I can find while searching just mentions that the adaptive bitrate switching is automatic. Is there any specific information on how a switch from a higher bitrate to a lower bitrate is triggered, and does an iOS app developer have any control over when this occurs?

1I'm not an iOS developer, but the streams will switch based on the network bandwidth availability at the end user. – Sathish Mar 18 '14 at 07:39

i'd like to add that serious adaptive bitrate players make their decisions based on CPU load, player size and of course bandwidth. – rshmelev Mar 18 '14 at 15:27
