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)299.466666667print a.time_total(0) / 604.99111111111 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.
Thanks!That finally did it. Two lines of code, one to open the file and one to get the run time replace eight lines of opening and reading pipes, then parsing the output and converting from string to integers then multiplying and adding. Much simpler this way. I knew that this had to exist, I just didn't have the expertise to figure out how to find it.
Then end results are identical to what I get from parsing the output of ogginfo, but this is a pure python solution, which I like much better.
BTW, this method is almost exactly the same as for using pymad to get the info from an mp3 file. The only differences are the module and function used to open the file, and in pymad, the function is total_time(), instead of time_total(0).
