See, most of ogg vorbis files have variable bitrate, so the way to calculate its mean bitrate -- the only significant bitrate when speaking of the whole stream -- is size/duration, what imply you must know the duration beforehand. I'm afraid you can't know the duration of the stream by just looking at the file size, since even libvorbis must be able to seek through the stream to be able to determine it's duration. -- Lucas Clemente Vella [email protected] _______________________________________________ Vorbis-dev mailing list [email protected] http://lists.xiph.org/mailman/listinfo/vorbis-dev
