Playing a .cue file directly will now parse the .cue file, and load and play the file(s) referenced in the cue. If multiple files are referenced, a timeline including all files will be created to create the impression of a single, flat audio file containing all the tracks. For each track, a chapter is created. The chapter navigation commands can be used to jump between tracks. The chapter titles will use the string provided by the track's TITLE cue command. (The -identify command can be used to print all chapters in a not so user friendly way.) Other than the chapter names, there is no attempt at displaying or exposing any other meta data contained in the cue files yet. The handling (or lack of thereof) of gaps (track pregaps and postgaps) is probably not correct yet. In general, mplayer's mapping of tracks to the source audio files can be verified by examining the timeline, which will be printed when passing the -v switch. Note that this has nothing to do with the old cue:// support. The old code isn't touched, and is still only able to play .cue/.bin pairs. Prefixing a .cue file with cue:// will always invoke the old code, while playing a .cue file directly (i.e. "mplayer file.cue") will always use the new code. Playing audio images (.cue/.bin pairs of files) doesn't work yet.
