这篇文章主要介绍了利用php获得flv视频长度的实例代码,需要的朋友可以参考下
废话不多说了，直接给大家贴代码了，具体代码如下所示：
BigEndian2Int(fread($fp,4));
$flv_header_frame_length = 9;
if ($frame_size_data_length > $flv_header_frame_length) {
fseek($fp,$frame_size_data_length - $flv_header_frame_length,SEEK_CUR);
}
$duration = 0;
while ((ftell($fp) + 1) < $flv_data_length) {
$this_tag_header = fread($fp,16);
$data_length = $this->BigEndian2Int(substr($this_tag_header,3));
$timestamp = $this->BigEndian2Int(substr($this_tag_header,8,3));
$next_offset = ftell($fp) - 1 + $data_length;
if ($timestamp > $duration) {
$duration = $timestamp;
}
fseek($fp,$next_offset,SEEK_SET);
}
fclose($fp);
return $duration;
}
//转化为0：03：56的时间格式
function getFlvTime($time){
$num = $time;
$sec = intval($num/1000);
$h = intval($sec/3600);
$m = intval(($sec%3600)/60);
$s = intval(($sec%60));
$tm = $h.':'.$m.':'.$s;
return $tm;
}
