[mpg123-devel] OSC for mpg123 (experimental)

[<to...@tr...>]

Hi,

in order to control the mpg123 player with OSC (Open Sound Control), i
tried to modify the control_generic.c interface and it seems to work OK.

For anyone interested to test, this is how to proceed (for current version
1.15.0):

Install liblo
-http://liblo.sourceforge.net/
from source or with the package manager of your choice

Get mpg123 source
$ svn co svn://scm.orgis.org/mpg123/trunk

Copy attached files
-osc.h
-control_generic.c
-mpg123.c
-configure.ac
to src/
(diff or meld to see difference)

then issue
$ autoreconf -iv
$ ./configure

if all went fine, you should see
  Liblo ................... enabled
  OSC control interface ... enabled

$ make
$ sudo make install


$ /usr/local/bin/mpg123 --longhelp
....
....
--osc_port         start osc udp server on port
--osc_id           set id, i.e. 'p1' will be addressed in osc as /p1
--osc_to_host      send msg to this host, regardless of request source
--osc_to_port      port of host where msg is sent to
--osc_help         show osc commands

The most easy way to start is
$ /usr/local/bin/mpg123 --remote --osc_port 1234

@OSC INFO Starting OSC UDP Server with these Properties:
@OSC INFO My Port:                 1234
@OSC INFO My ID:                   p1
@OSC INFO Sending Reports to Host: localhost:3333
@OSC REC SELFTEST /self/test 0.123400, 56 "a string"
@R MPG123 (ThOr) v7

You can use all ThOr commands now via OSC:

$ oscsend 10.10.10.20 1234 /cmd s "load my.mp3"

Some new ThOr commands here:
@H UNSILENCE: be verbose again
@H INTERVAL <int>: set report interval, every nth cycle
@H SHOWINTERVAL: print current interval
@H SHOWLOADED: print currently loaded file
@H SHOWPAUSE: print current pause status

Please feel free to comment and feedback. The code is *not* beautiful at
all. I would be interested to know if it builds on other machines.

Best regards,
Thomas
