Detailed Description

EDL support.

Most media files contain one or more A/V streams. In addition however, there can be additional instructions, how the media should be played back. Basically you can have "logical" streams, where the EDL tells how they are composed from phyiscal streams.

To use EDLs with Gmerlin-avdecoder, call bgav_get_edl, make a local copy of the EDL structure and call bgav_close.

Some files contain only the EDL (with external references) but no actual media streams. In this case, bgav_num_tracks will return 0.

Gmerlin-avdecoder has no means of composing the logical EDL tracks from physical files. The Gmerlin library has an edl decoder plugin.
