问题描述

我有这个页面（很简单，显示我需要）上传flv文件 - 我读了一些关于ffmpeg-php的文章，但是如何在服务器上安装如果是解决方案和如何使用它？

 <？php 
 if（isset（$ _ REQUEST ['upload']））{
 $ tmp_name = $ _FILES [ '视频'] [ 'tmp_name的值']; 
 $ name = $ _FILES ['video'] ['name']; 
 $ path =videos /; 
 move_uploaded_file（$ tmp_name，$ path。$ name）; 
} 
 else {

< / form> 
<？php 
}

并且需要为其他文件夹中上传的同名视频创建缩略图
任意帮帮我 ？在此先感谢

解决方案

安装ffmpeg应该很简单。在任何基于Ubuntu / Debian的发行版中，使用apt-get：

  apt-get install ffmpeg 
  

之后，您可以使用它创建缩略图。

首先，您需要从文件中获取随机时间位置：

  $ video = $ path。 escapeshellcmd（$ _ FILES [视频] [名称]）; 
 $ cmd =ffmpeg -i $ video 2>& 1; 
 $ second = 1; 
 if（preg_match（'/ Duration：（（\d +）:( \d +）:( \d +））/ s'，`$ cmd`，$ time））{
 $ total =（$ time [2] * 3600）+（$ time [3] * 60）+ $ time [4]; 
 $ second = rand（1，（$ total  -  1））; 
 
 $ / code> 

现在你的 $ second 变量被设置。获取实际缩略图：



  $ image ='thumbnails / random_name.jpg'; 
 $ cmd =ffmpeg -i $ video -deinterlace -an -ss $ second -t 00:00:01 -r 1 -y -vcodec mjpeg -f mjpeg $ image 2>& 1; 
 $ do =`$ cmd`; 
  

它会自动将缩略图保存到 thumbnails / random_name.jpg （您可以根据上传的视频更改该名称）

如果要调整缩略图大小，请使用 - 参数（ -s 300x300 ）

查看ffmpeg文档，查看可以使用的参数的完整列表。

i have this page (very simple to show what i need) to upload flv files - i read some posts about ffmpeg-php but how to install in on the server if it's the solution and how to use it?

<?php
if(isset($_REQUEST['upload'])){
$tmp_name = $_FILES['video']['tmp_name'];
$name = $_FILES['video']['name'];
$path = "videos/";
move_uploaded_file($tmp_name,$path.$name);
}
else{
?>
<form action="" method="post" enctype="multipart/form-data">
<input name="video" type="file" /> <input name="upload" type="submit" value="upload" />
</form>
<?php
}
?>

and need to create a thumbnail for video uploaded in another folder with the same name any help ? thanks in advance

解决方案

Installing ffmpeg should be straightforward. On any Ubuntu/Debian based distro, use apt-get:

apt-get install ffmpeg

After that, you can use it to create a thumbnail.

First you need to get a random time location from your file:

$video = $path . escapeshellcmd($_FILES['video']['name']);
$cmd = "ffmpeg -i $video 2>&1";
$second = 1;
if (preg_match('/Duration: ((\d+):(\d+):(\d+))/s', `$cmd`, $time)) {
    $total = ($time[2] * 3600) + ($time[3] * 60) + $time[4];
    $second = rand(1, ($total - 1));
}

Now that your $second variable is set. Get the actual thumbnail:

$image  = 'thumbnails/random_name.jpg';
$cmd = "ffmpeg -i $video -deinterlace -an -ss $second -t 00:00:01 -r 1 -y -vcodec mjpeg -f mjpeg $image 2>&1";
$do = `$cmd`;

It will automatically save the thumbnail to thumbnails/random_name.jpg (you may want to change that name based on the uploaded video)

If you want to resize the thumbnail, use the -s parameter (-s 300x300)

Check out the ffmpeg documentation for a complete list of parameters you can use.
