Patch against ogg123 in vorbis-tools 1.0 to support vorbiscomment output to file. (c) 2003 M.J.London This patch should be applied against vorbis-tools-1.0, it will patch the vorbis-tools-1.0/ogg123/ directory. Apply it in the usual way using patch: cd vorbis-tools-1.0/ patch -p1 <~/ogg123-ml1.patch Then build vorbis-tools in the usual way. Once you've rebuilt ogg123, you can use the comment output function by using the -g switch: $ ogg123 -g /tmp/ogg123-comment somefile.ogg $ cat /tmp/ogg123-comment You should find the file contains the raw comment data (no, it doesn't change case of the key ATM). Have fun :&) --Matt
