Detailed Description

C++ wrapper for mlt_parser — walks a service network and fires callbacks.

Subclass Parser and override the virtual on_start and on_end methods to inspect or transform every node in a service graph(producers, playlists, *tractors, filters, transitions, chains, links). Call start() to begin traversal.
