it appears to me that ffmpeg is unaware of 'cue ' chunks in wav files, for
reading and writing. ffmpeg supports cues or chapter markers for other
container formats.
this involves
- a 'cue ' chunk that contains a table of timestamps (the 'fmt ' chunk may
be useful to convert sample indices to times)
- a 'list' 'adtl' chunk that contains 'labl' chunks
- 'labl' chunks that each contain an index and a string label, which
describes the given cue point
the RIFF/WAV file specification details the structures of these chunks. I
suspect that this doesn't just apply to wav files but also avi files.
I'll attach a sample file that contains a few cue points.
