This is a question that I have considered for some time for all the

For us, with a third-party black box media player sitting at several levels
of abstraction away (and sometimes on a separate processor), we do not have
access to most of the information that is necessary to drive the algorithms.
For example, network usage (if indeed there is any at all), which frames you
have, seekable ranges, buffering statistics - all of these are unavailable.
