我有一个网站,允许用户上传视频。但是使用HTML5标签视频时,只允许MP4格式的视频。
因此,我想将用户上传的任何类型的视频转换为MP4格式,然后将路径添加到我的数据库中。
我尝试了一些方法,将文件扩展名更改为MP4,但没有成功。我读到了一些关于ffmepg的内容,但我不知道如何使用它。
这是我的PHP脚本,在其中更改文件扩展名,然后将路径添加到我的数据中,请问我应该如何正确地转换视频,需要添加/更改什么?
<?php
if(file_exists($_FILES['media-vid']['tmp_name']) && is_uploaded_file($_FILES['media-vid']['tmp_name']))
{
$targetvid = md5(time());
$target_dirvid = "videos/";
$target_filevid = $targetvid.basename($_FILES["media-vid"]["name"]);
$uploadOk = 0;
$videotype = pathinfo($target_filevid,PATHINFO_EXTENSION);
$video_formats = array(
"mpeg",
"mp4",
"mov",
"wav",
"avi",
"dat",
"flv",
"3gp"
);
foreach ($video_formats as $valid_video_format)
{
if (preg_match("/$videotype/i", $valid_video_format))
{
$target_filevid = $targetvid . basename($_FILES["media-vid"] . ".mp4");
$uploadOk = 1;
break;
}
else
{
//if it is an image or another file format it is not accepted
$format_error = "Invalid Video Format!";
}
}
if ($_FILES["media-vid"]["size"] > 5000000000000)
{
$uploadOk = 0;
echo "Sorry, your file is too large.";
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0 && isset($format_error))
{
echo "Sorry, your video was not uploaded.";
// if everything is ok, try to upload file
}
else if ($uploadOk == 0)
{
echo "Sorry, your video was not uploaded.";
}
else
{
$target_filevid = strtr($target_filevid,
'ÀÁÂÃÄÅÇÈÉÊËÌÍÎÏÒÓÔÕÖÙÚÛÜÝàáâãäåçèéêëìíîïðòóôõöùúûüýÿ',
'AAAAAACEEEEIIIIOOOOOUUUUYaaaaaaceeeeiiiioooooouuuuyy');
$target_filevid = preg_replace('/([^.a-z0-9]+)/i', '_', $target_filevid);
if (!move_uploaded_file($_FILES["media-vid"]["tmp_name"], $target_dirvid. $target_filevid))
{
echo "Sorry, there was an error uploading your file. Please retry.";
}
else
{
$vid= $target_dirvid.$target_filevid;
$nbvid = 1;
}
}
}
?>
谢谢。
