Today we are on-boarded to using CMCD data to allow us to get more diagnostic data of our streaming. We would like to have the ability to upload our own custom headers, this is supported on other players, but not supported on AVPlayer. The workaround today that works is adding in custom query parameters then querying based on that, but we would like support explicitly in the headers.

These are follow up questions for: https://feedbackassistant.apple.com/feedback/22779473 For a large AVQueuePlayer queue (50-100+ HLS items), does AVFoundation guarantee it only allocates video decode sessions for the active and next item? Our profiling suggests this is the case, but we want to confirm whether we can rely on this behavior or if we should implement an application-side sliding window to limit concurrent decoders.
