Parses creation date from media metadata.
Description
The getID3 library doesn’t have a standard method for getting creation dates, so the location of this data can vary based on the MIME type.
Parameters
$metadataarrayrequired- The metadata returned by getID3::analyze().
Source
function wp_get_media_creation_timestamp( $metadata ) {
$creation_date = false;
if ( empty( $metadata['fileformat'] ) ) {
return $creation_date;
}
switch ( $metadata['fileformat'] ) {
case 'asf':
if ( isset( $metadata['asf']['file_properties_object']['creation_date_unix'] ) ) {
$creation_date = (int) $metadata['asf']['file_properties_object']['creation_date_unix'];
}
break;
case 'matroska':
case 'webm':
if ( isset( $metadata['matroska']['comments']['creation_time'][0] ) ) {
$creation_date = strtotime( $metadata['matroska']['comments']['creation_time'][0] );
} elseif ( isset( $metadata['matroska']['info'][0]['DateUTC_unix'] ) ) {
$creation_date = (int) $metadata['matroska']['info'][0]['DateUTC_unix'];
}
break;
case 'quicktime':
case 'mp4':
if ( isset( $metadata['quicktime']['moov']['subatoms'][0]['creation_time_unix'] ) ) {
