Take comments from a file. The file is the same format as is output by the the -l option: one element per line in 'tag=value' format.
-h
Show command help.
-l
List the comments in the ogg vorbis file.
-q
Quiet mode. No messages are displayed.
-t 'tag=value'
Specify a new tag on the command line. Each tag is given as a single string. The part before the '=' is treated as the tag name and the part after as the value.
-w
Replace comments with the new set given either on the command line with -t or from a file with -c.
-R
Read and write comments in utf8, rather than converting to the user's character set.
EXAMPLES
To just see what comment tags are in a file:
vorbiscomment -l file.ogg
To edit those comments:
vorbiscomment -l file.ogg > file.txt
[edit the comments in file.txt to your satisfaction]
vorbiscomment -w -c file.txt file.ogg newfile.ogg
To simply add a comment:
vorbiscomment -a -t 'ARTIST=No One You Know' file.ogg newfile.ogg
