Sorry. __dict__ is class metadata, so that should have been something
along the lines of:
import pyvorbis
print pyvorbis.<class name>.__dict__
I don't have pyvorbis at work, so I can't check this myself right now.
I've poked around with ogg.vorbis, and I got the following:
import ogg.vorbis
a = ogg.vorbis.VorbisFile('./music/t_o_p/track01.cdda.ogg')
print a.__methods__
['bitrate', 'bitrate_instant', 'comment', 'info', 'pcm_seek',
'pcm_seek_page', 'pcm_tell', 'pcm_total', 'raw_seek', 'raw_tell',
'raw_total', 'read', 'seekable', 'serialnumber', 'streams',
'time_seek', 'time_seek_page', 'time_tell', 'time_total']
print a.time_total(0)
299.466666667
print a.time_total(0) / 60
4.99111111111
This track is, according to ogg123, just a hair under 5 minutes. I
have no idea what the argument to time_total is supposed to mean, but
it has to be a non-positive integer, apparently. All negative
integers I tried yield the same result as 0.
