Re: Play mp3 by perl.

Check out Bundle::XMMS over at CPAN. It can control the XMMS multimedia player. I used it quite successfully a while back to drive an MP3 alarm clock. It would come on quietly then slowly increase the volume until I got up and shut it off.

Update: Also check out Audio::Play::MPG123 and MPEG::MP3Play. I have not used these modules so I can't say much about them.

Do you still have the code for the alarm clock that you implemented? I would like to see how you did that...if you don't mind.

I'm afraid the code disappeared with most of my other projects in the Great Grinding Hard Drive Crash. The project itself was pretty simple and shouldn't be hard to reimplement.

I just used a flat text file with lines in the format of "DAY:HH:MM", so for example, "FRI:5:45" for Friday at 5:45 AM. The program ran as in infinite loop, sleeping 45 seconds at a time, then running through and comparing the times in the configuration file to the current time. If it found a match it would jump into playback mode.

In this mode, a file was selected (hardcoded) and the volume reduced to zero. It would also unlink the file ~/.alarm if it existed. The playback loop would then begin, incrementing the volume slowly until either ~/.alarm was created or the volume was at 100% for a full minute. The program would then reset the volumn to a normal level, stop play, and reenter the main loop.

I had an icon on my desktop that ran "touch ~/.alarm", so all that I had to do was turn on the monitor and click on it.
