I'm currently developing a high-level wrapper for FFMPEG at
https://github.com/nordlow/justd/blob/master/tests/t_ffmpeg.d
My question now becomes how to most easily wrap the iteration
over streams at
https://github.com/nordlow/justd/blob/master/tests/t_ffmpeg.d#L150
https://github.com/nordlow/justd/blob/master/tests/t_ffmpeg.d#L152
in a nice D-style range interface.
Do I have to allocate a new D array and copy the `AVStream*`
elements into that or is there a convenience wrapper for
constructing a lazy range from a C style Array-pointer plus
array-length?
Note that the elements of the C array are pointers to structs, in
this case instances of `AVStream`. This, of course, complicates
the matter with regard to GC-safety.
Comments on that please :)
