[PHP] duration of mp3 file
Allow bunnies ... Any takers on this ... I JUST want the duration of the mp3 file - with a small function if possible ... I honestly don't want to use a class like http://www.phpclasses.org/browse/package/112.html The coding is terrible and SERIOUSLY over inflated for what I want. Anyone know of a simple class / function ? S -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

So why not take the part that you need and rewrite it so that it is not so terrible? -- Crayon -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Or you could use ffmpeg executable to get details about the media file. You will have to parse the response of the executable. The only thing is that you must have exec function or an execution function available and ffmpeg installed. This is for linux machines tho... Don't know if ffmpeg is available for windows too.

Or you can use sox, if you compile it with mp3 support. It works for me... -Original Message- From: Andrei [EMAIL PROTECTED] To: 'Jim Moseby' [EMAIL PROTECTED] Cc: php-general@lists.php.net Sent: 07. 07. 11. 16:25 Subject: Re: [PHP] duration of mp3 file Or you could use ffmpeg executable to get details about the media file.

Anyone know of a simple class / function ? id3_lib and/or the PHP ID3 project may or may not let you pull the duration out of the early frames of the MP3... Though those are also quite a bit over-inflated for what you want... If all else fails, and if a reasonable margin of error is acceptable... A CRUDE hack to get an estimate, if you know in advance that all the files are a certain audio quality, is to just divide the filesize by some factor that's an average of the ratio between duration/filesize of some known sample files... I often eyeball an MP3 filesize in the shell and can tell you to within a few seconds how long it is, just based on filesize, as they are all stereo 128K, at least in my collection. Except the ones named lofi which are mono 64K, and that's a different ratio is all :-) The point being that if it's just eye candy to tell the user how long the thing is, you don't NEED microsecond accuracy anyway, just do something like: //very crude estimate, if I did the math in my head right... $ratio = 6000; //128K, stereo, a meg a minute, give or take... $filesize = filesize($mp3); $duration = $filesize / $ratio; $minutes = floor($duration / 60); $seconds = $duration - ($minutes * 60); echo $minutes:$seconds minutes; Sometimes we programmers get so wrapped up in perfection and detail work, we ignore a seemingly overly simplistic solution, to our detriment. -- Some people have a gift link here.
