Kai, I don't suppose you have FILE_IO_EDL implemented yet, do you ?
That is, I/O to and from a "file" that is accompanied by an edit
decision list. The actual "file" may consist of one or more disk files.
I'm going to need to do this for Ardour in the fall. It seems quite
difficult to do with buffering etc.
If anyone wants to volunteer to write such a beast, that would be great.
