major modes . it should be not necessary to define
|
|
new modes.
|
|
What are "major modes"?
|
|
<p>
|
|
The idea of the major modes, is that this is a very
|
|
general description of an abstract cd player.
|
|
When the decoder works yaf send these
|
|
major modes to the frontend.
|
|
<p>
|
|
These Major modes describes the basic commands which
|
|
every yaf-decoder implementation should support:
|
|
<pre>
|
|
on/off
|
|
open/close
|
|
pause/play
|
|
</pre>
|
|
Thus it is possible that a frontend works with
|
|
a decoder even if the frontend does not fully support all
|
|
the commands (e.g: switch to mono etc...)
|
|
|
|
<pre>
|
|
If you think you have a new "mode" its almost a "feature"
|
|
eg: You have a command "jump" but this is not a "mode"
|
|
because you can press "jump" on your cd player even
|
|
if the cd player is off OR on OR playing OR paused
|
|
In all these cases the command does not affect the
|
|
state of your cd-player. Or do you have a player
|
|
which switches itself on if you press e.g. "Track 1" ?
|
|
</pre>
