mp123, OS/2 port of the fast Mpeg Audo Player mpg123
----------------------------------------------------
This is the official OS/2 port of mpg123, approved by Michael Hipp,
the author of the mpg123 source. Please read the README file to
find out more about the source code package this player is based on.
I'm calling this port mp123 instead of mpg123 because there is
already another port of mpg123 floating around and that one is
called mpg123.
This version of mp123 is able to play Layer I, II and III MPEG-1.0
MPEG-2.0 and almost IIS MPEG-2.5 audio streams (mp123 plays MPEG-
2.5 Layer 3 streams but it sounds pretty bad).
This is as far as I know the fastest MPEG Audio player for OS/2
you can find (at least for free). It is even a lot faster than the
other mpg123 port (mpg123v3.zip on hobbes).
It supports wildcards as file-argument and http-url if you want to
stream audio to the player from the web. You can even let it read
one of those famous .m3u-files (mpeg3url) as a playlist (-@ http-
url) and it will then stream the .mp3 files in that mpeg3url.
I made a small command-file (mp123url.cmd) that executes mp123.exe
with the argument as a playlist. That makes it possible to use it
as a helper-application in Netscape for .m3u url's...:
- Select Options->General preferences...
- Go to the "Helpers"-tab
- Press the "Create new type..."-button (if you don't already have
the "audio/x-mpegurl" in the File Type list)
- Enter "audio" in the Mime Type field
- Enter "x-mpegurl" in the Mime SubType field and press OK
- Enter "m3u" in the File Extention field
- Select the "Launch the Application" radio button
- Press the Browse-button and select the mp123url.cmd file
- OK, you are ready to play...
If your system is slow (486dx2 or worse) you can use the downsample-
switch (-2 or -4) to make mp123 decode only every second or every
fourth sample and play the result as 1/2 or 1/4 of the sampling-
frequency (44100 KHz becomes 22050 or 11025 KHz).
Another switch that saves CPU is the monomix-switch (-m) and that
one makes mp123 mix left and right channel to one mono channel.
Or why not use both ( mp123 -2 -m *.mp* ) to get really low CPU-
utilization.
This package needs the emx runtime libraries so if you don't
already have it, get emxrt.zip from hobbes.nmsu.edu and install it.
