1) Basic troubleshooting and problems.
=============================================================================
1.1 ) When I try to play a song, I get a 'mpg123 stopped sending data'
error, what's wrong?
Make sure you are using mpg123 version 0.59o or greater.
On FreeBSD, SGI IRIX 5.3, Linux/PPC, and most other non-x86 linux platforms
use mpg123 0.59q. When using 0.59o or 0.59p mpg123 needs to be compiled
with -DREAD_MMAP enabled in mpg123's Makefile.
(If you find this applies to other systems/platforms, contact me to have
that system added to this list)
------------------------------------------------------------------------------
1.2 ) When I play a song, the time display is not updated and the position
scrollbar does not work, what's wrong?
Make sure you are using mpg123 version 0.59o or greater.
On FreeBSD, SGI IRIX 5.3, Linux/PPC, and most other non-x86 linux platforms
use mpg123 0.59q. When using 0.59o or 0.59p mpg123 needs to be compiled
with -DREAD_MMAP enabled in mpg123's Makefile.

------------------------------------------------------------------------------
1.3 ) Sometimes when skipping or seeking within a song during playback,
GQmpeg prints a 'mpg123 reported: can't open /dev/dsp' error, and
drops into a paused state.
As of 0.4.4 this should be fixed.
There are reports that even versions after 0.4.4 have this problem
when used with the 2.2.0 Linux kernel.
------------------------------------------------------------------------------
1.4 ) When loading a playlist with files on a cd-rom, it seems to take
forever, can I speed this up?
Try disabling the reading of file headers and id3 tags on the General tab
of the configuration window. This should decrease the number of file
accesses when loading the playlist.
------------------------------------------------------------------------------
1.5 ) When I have a playlist with more than 999 songs, why are the song
counters not correct.
The Display is only capable of showing three digits, however playlists
with more than 999 songs work correctly.
Update: As of 0.5.0 skins can support more than 3 digits, using such skins
will fix the problem.
------------------------------------------------------------------------------
1.6 ) When using freeamp to emulate mpg123, why is GQmpeg's cpu utilization
display always zero?
Freeamp uses multiple threaded processes when running. The initial process
started by freeamp is the one monitored by GQmpeg, and is not the CPU
intensive decoder thread.
------------------------------------------------------------------------------
1.7 ) When using GQmpeg as a shoutcast netscape plugin it crashes.
Shoutcast support is currently buggy at best. Shoutcast requires
mpg123 0.59pre-p ... mpg123 0.59o WILL NOT WORK!
Not included in binary packages. See the shoutcast dir in the source code.
------------------------------------------------------------------------------
1.8 ) My home directory is across a network, and gqmpeg seems to be
constantly polling a file there, can I disable it?
Disable the 'allow command parsing...' option under preferences->general.
This will stop GQmpeg testing for a ~/.gqmpeg/command file every 3 seconds.
------------------------------------------------------------------------------
1.9 ) When I attempt to load a skin other than the default, GQmpeg crashes,
why?
Make sure GQmpeg was compiled with gtk 1.0.6 and imlib 1.8.x _or_
gtk 1.2.x and imlib 1.9.x. Do not mix gtk 1.0.6 and imlib 1.9.x!
------------------------------------------------------------------------------
1.10) Why isn't my video4linux radio card/tuner detected?
Check that other radio programs work, examples are radio (included with
xawtv) and kradio. Radio is on supported under linux. The most common
problem is that video4linux it is not configured correctly - check that the
required kernel modules are being loaded when /dev/radio is accessed.
------------------------------------------------------------------------------
1.11) Why is radio auto-scan not picking up any stations?
The radio/tv card (or it's driver) does not support or implement signal
strength reporting. Another cause are weak radio in your area - try
adjusting the antenna position.
=============================================================================
2) How do I ... ?
=============================================================================
2.1 ) How do I do this via the keyboard?, what are the keyboard shortcuts?
Please see the README for a complete list of keyboard commands.
------------------------------------------------------------------------------
2.2 ) How do I add an entire directory to a playlist? And how can I add
them recursively?
Using the mouse, right click on a directory in the playlist window and
select the desired operation from the pop-up menu that appears.
------------------------------------------------------------------------------
2.3 ) How do I play mpg123 through Esound?
The easiest solution is to use the esound patched version of mpg123,
available on the Esound home page:
http://www.tux.org/~ricdude/EsounD.html
mpg123 version 0.59q includes built-in Esound support. (compile option)
=============================================================================
3) Why isn't ... feature implemented / supported ?
=============================================================================
3.1 ) Why do I have to use mpg123? I want to use another player engine.
Currently there is one other player that works with GQmpeg. Freeamp can
emulate mpg123's interface and therefore will work with GQmpeg. Freeamp
is available at www.freeamp.org
------------------------------------------------------------------------------
3.2 ) The mixer/volume controls do not work, are they supported on my
platform?
Currently the mixer/volume controls are known to work on Linux, FreeBSD,
and SPARC Ultra 1 w/ sun 2.5.1, patches to support other platforms will
be accepted.
------------------------------------------------------------------------------
3.3 ) Why is there no spectrum analyser?
GQmpeg is a frontend, and by nature does not have access to the sound's
data stream. (although this may be possible with Esound)
------------------------------------------------------------------------------
3.4 ) Why is there no plugin support like other players?
See 3.3 Update: this answer is subject to change :)
