如何使用 PHP 对视频进行编码？
我有兴趣在我的服务器上安装 ffmpeg 或类似的东西，以便我可以上传文件，自动将它们编码为 FLV，然后提供嵌入式播放器以在我的页面上使用。
问题是我不知道从哪里开始。我不想花几天时间编写基于 Web 的编码服务，因为我对使用开箱即用的解决方案更感兴趣。
到目前为止，我的研究使我找到了 FFMPEG 以及可能的 Gallery2：它集成了 ffmpeg，gallery 2 框架提供用户帐户和FTP 上传设施。
有人知道可以在 Linux 上安装的其他开源编码解决方案吗？
I'm interested in installing ffmpeg or somesuch on my server so I can upload files, automatically encode them to FLV and then serve up a embedded player to use on my pages.
The problem is that I don't know where to start. I don't want to have to spend days coding a web based encoding service, as I'm more interested in using an out of the box solution.
My research so far has led me to FFMPEG and possibly Gallery2: it has a ffmpeg integrated and the gallery 2 framework provides user accounts and FTP upload facilities.
Is anyone aware of other open source encoding solutions which you can install on Linux?

有 PHP 的 ffmpeg 扩展。
There is ffmpeg extension for PHP.
还有
memcoder，它的作用与ffmpeg可以，但是您必须对绑定ffmpeg/memcoder、PHP以及上传的视频。一般工作流程类似于：
post上传CLI带有所有所需参数的命令并将文件存储在另一个已知位置There is also
memcoder, that does the same thing thatffmpegdoes, but you will have to code the glue that bindsffmpeg/memcoder,PHPand the uploaded videos together.The general workflow would be something like:
postCLIcommand with all the desired parameters and store the file in another known location您还可以查看 VLC，因为它可以转码并充当 FLV 流的服务器。主要应用程序是用于播放视频的用户界面，但可以从命令行调用它来执行服务 - 而不是播放。
还有 libvlc，它是编写 VLC 的 C 库。 VLC 基于 ffmpeg，可能会让您的生活更轻松一些。
You could also have a look at VLC since it can transcode and act as a server for your FLV streams. The main application is a user interface to playback the video but it can be invoked from the command-line to do the serving - rather than playing.
Also there is libvlc which is the C library upon which VLC is written. VLC is based upon ffmpeg and might just make your life a little easier.
您应该查看您选择的编码器的文档，我过去曾成功使用过 ffmpeg。然后你的工作流程看起来像这样。
ffmpeg 非常容易通过几个命令行参数启动和运行。
You should check out the docs for your chosen encoder, I have used ffmpeg successfully in the past. Then your workflow looks something like this.
ffmpeg was really easy to get up and running with a couple of command line arguments.
