It would seem that NRG files for audio discs have a pre-gap field for
each track in the DAOX structure as "documented" at
http://en.wikipedia.org/wiki/NRG_(file_format). I checked it out, and
this does in fact seem to be the case, although the byte order is
reversed (I most likely need to use some macro like UINT64_FROM_BE.) I
modified nrg.c to dump the pre-gap, start of track, and end of track
from the DAOX structure. (I used cdio_warn.)
So, we're back to the age old question of how to export this
information. What is your opinion of the following for an API?
lsn_t cdio_get_track_pregap_lsn(const CdIo_t *p_cdio, track_t i_track);
I would have it return CDIO_INVALID_LSN if the data isn't available.
Thoughts, questions, concerns?
Regards,
Rob
