Dear List,
First, i think i should thanks all the contributors of MPD.
Thank you guys, you guys are great, made a really great player!
Recently, from my work experiences, i had an idea that is i want to build a
special player upon MPD(or maybe a control interface at least) which was
targeted for a radio programme playback.
And which also has some special needs of the player, and after i digging
around MPD for a while, i still don't had clues to figure that out.
So, my question is:
Is it possible to do the following thing from the current *API/protocol of
MPD provided*?
1) Get the 'About to finish' signal or sth. similar before the actual
'player' idle signal; *# Which is useful if you want do some extra
control/actions/check ups before the next one being played;*
Any client can predict when a song will finish by comparing total
duration and current position.
2) Set one or more songs to be played at a pre-defined fixed time
exactly; *# Which is useful for radio programme, you know something
should be played at a specific time, like news update;*
echo mpc play |at 5am
You mean like this?
This is the perfect example of a feature that shouldn't be added to
the MPD core, because mpc plus some existing tool can do it already.
3) Play couple of songs continuously then stop at some pre-defined
position, waiting for DJ's break. Which requires you can define the
playback logic in advance, not by switch the mode to 'single' before the
stop point manually;
Repeat mode?
This idea looks so arbitrary, no matter how many rules we implement,
somebody else will want a new rule. So either we will end up with a
built-in scripting language which is too complicated for users to
understand, or we will have a complex rule set that is also too
complicated for users to understand.
Or just implement such a logic in a special client. Which is easier
to extend than the MPD core.
4) Clear/Eject the current playlist and load a brand new playlist while
the dates changed from one day to another at a regular point, like
2012-05-19 23:59:59 - 2012-05-20 00:00:00.
echo mpc load foo |at midnight
