note 90970 added to function.swfmovie.streammp3

Hey all, For those using Ming 0.3 (like me), there is a way to calculate the length of the MP3 you are using. It might be a bit iffy for VBR files, but it seems to work well for the files I've tested thus far. <?php function get_mp3_len ($file) { $rate1=array(0, 32, 64, 96, 128, 160, 192, 224, 256, 288, 320, 352, 384, 416, 448, "bad"); $rate2=array(0, 32, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256, 320, 384, "bad"); $rate3=array(0, 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256, 320, "bad"); $rate4=array(0, 32, 48, 56, 64, 80, 96, 112, 128, 144, 160, 176, 192, 224, 256, "bad"); $rate5=array(0, 8, 16, 24, 32, 40, 48, 56, 64, 80, 96, 112, 128, 144, 160, "bad"); $bitrate=array( '1' => $rate5, '2' => $rate5, '3' => $rate4, '9' => $rate5, '10' => $rate5, '11' => $rate4, '13' => $rate3, '14' => $rate2, '15' => $rate1 ); $sample=array( '0' => 11025, '1' => 12000, '2' => 8000, '8' => 22050, '9' => 24000, '10' => 16000, '12' => 44100, '13' => 48000, '14' => 32000 ); $fd=fopen($file, 'rb'); $header=fgets($fd, 5); fclose($fd); $bits=""; while (strlen($header) > 0) { //var_dump($header); $bits.=str_pad(base_convert(ord($header{0}), 10, 2), 8, '0', STR_PAD_LEFT); $header=substr($header, 1); } $bits=substr($bits, 11); // lets strip the frame sync bits first. $version=substr($bits, 0, 2); // this gives us the version $layer=base_convert(substr($bits, 2, 2), 2, 10); // this gives us the layer $verlay=base_convert(substr($bits, 0, 4), 2, 10); // this gives us both $rateidx=base_convert(substr($bits, 5, 4), 2, 10); // this gives us the bitrate index $sampidx=base_convert($version.substr($bits, 9, 2), 2, 10); // this gives the sample index $padding=substr($bits, 11, 1); // are we padding frames? $rate=$bitrate[$verlay][$rateidx]; $samp=$sample[$sampidx]; $framelen=0; $framesize=384; // Size of the frame in samples if ($layer == 3) { // layer 1? $framelen=(12 * ($rate * 1000) / $samp + $padding) * 4; } else { // Layer 2 and 3 $framelen=144 * ($rate * 1000) / $samp + $padding; $framesize=1152; } $headerlen=4 + ($bits{4} == 0 ? '2' : '0'); return (filesize($file) - $headerlen) / $framelen / ($samp / $framesize); } ?> ---- Server IP: 117.55.229.1 Probable Submitter: 137.166.16.38 ---- Manual Page -- http://www.php.net/manual/en/function.swfmovie.streammp3.php Edit -- https://master.php.net/note/edit/90970 Del: integrated -- https://master.php.net/note/delete/90970/integrated Del: useless -- https://master.php.net/note/delete/90970/useless Del: bad code -- https://master.php.net/note/delete/90970/bad+code Del: spam -- https://master.php.net/note/delete/90970/spam Del: non-english -- https://master.php.net/note/delete/90970/non-english Del: in docs -- https://master.php.net/note/delete/90970/in+docs Del: other reasons-- https://master.php.net/note/delete/90970 Reject -- https://master.php.net/note/reject/90970 Search -- https://master.php.net/manage/user-notes.php
