  AvFormatDecoder: Improve video frame rate selection

- instead of selecting one frame rate, we build a list of possible
values, the most likely/preferred first
- if the first choice is not a standard rate, iterate over the list and
see if there is something better available.
- this picks up errors from streams with some corruption, as well as
picking a better default for streams with a variable frame rate.
- should fix incorrect display mode switching - but further changes
needed to ensure we update the display mode on frame rate changes.
