这是我的问题:在我的网站上，我想允许用户上传任何类型的视频。但对于 HTML5 标签，只能使用 .mp4 视频。 所以我想将用户提交的任何类型的视频转换为MP4，然后添加数据库的路径。
我读过一些有关 FFmpeg 的内容，但我不知道如何使用它。我尝试使用 shell_exec("ffmpeg -i ".$vid."-vcodec libx264 -crf 20 out.mp4 2>&1") 但没有成功。
html
<form method="post" enctype="multipart/form-data" name="form" action="post.php">
<input type="file" name="media-vid" class=" file_multi_video" accept="video/*">
</form>PHP 脚本:
if(file_exists($_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 = 1;
$videotype = pathinfo($target_filevid,PATHINFO_EXTENSION);
if ($_FILES["media-vid"]["size"] > 500000000) {
$uploadOk = 0;
echo "Sorry, your file is too large.";
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
echo "Sorry, your video was not uploaded.";
// if everything is ok, try to upload file
} 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;
shell_exec("ffmpeg -i ".$vid." -vcodec libx264 -crf 20 out.mp4 2>&1");
}
}
}
最佳答案
这是我的做法:
试试这个代码! (经过测试，工作正常)
<form method="post" enctype="multipart/form-data" name="form">
<input type="file" name="media-vid" class=" file_multi_video" accept="video/*">
<input type="submit" name="submit" value="upload"/>
</form> <?
if (isset($_POST['submit'])) {
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);
//these are the valid video formats that can be uploaded and
//they will all be converted to .mp4
$video_formats = array(
"mpeg",
"mp4",
"mov",
"wav",
"avi",
"dat",
"flv",
"3gp"
);
foreach ($video_formats as $valid_video_format) {
//You can use in_array and it is better
if (preg_match("/$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"] > 500000000) {
$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 $message;
// if everything is ok, try to upload file
} else if ($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;
}
}
}
}
?>
测试一下并让我知道效果如何。如果您有任何其他问题或需要任何其他信息，请随时询问。我随时为您提供帮助，并且希望您对该文件进行完整编码。祝兄弟好运!
