MP3 file creation date #229
Comments
|
Quicktime files have creation and modification time scattered through various atoms. In theory they could be different from each other, although in most cases I would expect them to be identical (or close). To simplify user access to these numbers, Quicktime files now return an array of timestamps in In general practice you can probably assume that the timestamps are either all the same, or just grab the earliest one, for example: Fixed in 5967da6 |

Thanks! I did look at creation_time and creation_time_unix
e.g.
$ct = $ThisFileInfo['quicktime']['moov']['subatoms']['2']['creation_time'];
but the time returned is the script's run time! So very time I run the
script, I get a different value.

Oops! Sorry. Please ignore the previous comment. My conversion of the time
stamp to a readable format had a bug in it.
But thanks for your time and help. Much appreciated!

Sorry if I'm being dumb, but I can't get this to work: $info['quicktime']['
timestamps_unix']['create']
This simplified demo.basic.php:
require_once('getID3/getid3/getid3.php');
$getID3 = new getID3;
$filename = "albums/CapePoint/MVI_1657.MP4";
$ThisFileInfo = $getID3->analyze($filename);
$x = $ThisFileInfo['quicktime']['timestamps_unix']['create'];
echo("x=$x<br>");
$y = $ThisFileInfo['quicktime']['creation_time_unix']['create'];
echo("y=$x<br>");
echo '<pre>'.htmlentities(print_r($ThisFileInfo, true),
ENT_SUBSTITUTE).'</pre>';
results in this output:

Hi James
Will try not to waste any moire of your time!
I've written s simple recursive function to traverse the $fileinfo arrays
and in the process to pick out those bits I require for my application.
Thanks again for your time and for a very useful method to get meta data.
Regards
Franz

I'm curious about this. If you're able to send that sample file (or any sample file that produces this error) I would be interested in looking at it. Both for the error in the MP3 module (which is unexpected and shouldn't happen), and that it appears that the quicktime file does not contain any timestamps, which is also unusual. You can attach here, or email to info@getid3.org |

A simple script results in the snippet of the output below - but nowhere do I see the file's
creation date.
The code:
$filename = "albums/CapePoint/MVI_1657.MP4";
$ThisFileInfo = $getID3->analyze($filename);
The output:
Array
(
[GETID3_VERSION] => 1.9.19-201912131005
[filesize] => 90049761
[filepath] => C:/xampp/htdocs/gallery/albums/CapePoint
[filename] => MVI_1657.MP4
[filenamepath] => C:/xampp/htdocs/gallery/albums/CapePoint/MVI_1657.MP4
[avdataoffset] => 98312
[avdataend] => 90049761
[fileformat] => mp4
[audio] => Array
etc.
