Currently
Debug
only prints a raw pointer which is rather useless to look at. In addition to the pointer, also print theDisplay
representation ofMediaFormat
which uses Android'stoString()
function to create a human-readable string of the various fields set inside of it.On a side-note it is "great" to see that
toString()
is not currently available as a user function via a lifetimedCStr
as it is invalidated in a nontrivial way (e.g. whentoString()
is called again, and possibly also whenset_()
functions are called which are not currently borrowing it mutably).
