[vorbis-dev] [fwd] CVS: ogg123 rocks! vcut no so much so... (from: wayfarer42@postmaster.co.uk)

>I couldn't get --advanced-encoder-option to work.  However, it seemed to work as --advanced [option=whatever].

It's --advanced-encode-option (there was a mistake at one point in the 
manpage in 1.0 which indicated --advanced-encoder-option. Not sure why
--advanced works at all - maybe some quirk of getopt.

If the file works in ogg123, then it will work in Winamp and Xinf.  RC3 ogg123 would be graceful, but CVS ogg123 will hang to the point where Ctrl-C doesn't work, and I have to `killall ogg123` from another virtual console.  Something to work out?

Not sure about the ogg123 bug, but vcut is known to be very buggy. I wrote
it more as a proof-of-concept than as something for people to really use
much. It works for simple cases, but doesn't handle some things at all.

ogginfo in rc3 didn't actually work correctly in many, many cases. So I
rewrote it, and did the output in a nicer way. ogginfo was never intended
to be a tool for automated stuff like that (though you can doubtless still
do something), part of the reason for the new output format was a concious
desire to discourage it further (too many broken programs were using it
in particularly bad ways).
