If the there is no final 'out' point, the end-of-file is an implicit
'out'-point.
+Note that the PTS values are zero-based and continouus. If you want absolute
+PTS values, you can either:
+ - use the .ap file, find discontinuities, and interpolate between the APs
+ - or just use the first PTS value as an offset, and work around PTS
+ wraparounds. (simple method)
