最近在做一个视频网站安装本地环境费了不少时间。本地是ubuntu 9.10 而服务器是redhat as4 所以到时候本人会把服务器安装过程和大家分享出来。
本人环境如下
  • php —- 5.210
  • apache 2.2
  • ubuntu 9.10
  1. ffmpeg 功能很强大包括视频抓图,视频信息,视频转换,在线视频录制,而且是免费的。所有一般的视频网站都会采用他。
  2. 本人首先是采用编译安装,但是一直都没有成功。编译过程中出现了很多问题。安装要使用ffmpeg往往需要编译很多包。感觉很麻烦。这些包又依赖于很多其他包。安装顺序也有要求。所以放弃了。
  3. 最终采用ubuntu 强大的 apt-get (使用dpkg进行安装) 进行安装(当然cenos,red hat这类使用rpm的系统都可以使用yum进行安装,具体的安装方法可以在本站进行查找).
  4. apt-get 安装步骤如下:
    sudo apt-get update ##更新以下源
    sudo apt-get install ffmpeg
    sudo apt-get install php5-ffmpeg
    sudo apt-get install mencoder
    sudo apt-get install flvtool2 ##视频转换flv
    sudo apt-get install lame ##音频
    sudo apt-get install yasm
  5. 编译安装ffmpeg 如下:
    从 http://ffmpeg.mplayerhq.hu 下载
    ./configure –help ##查看有那些参数
    ./configure–prefix=/usr–enable-gpl–enable-shared–enable-libmp3lame–enable-libamr_nb–enable-libogg–enable-libvorbis–enable-libxvid–enable-liba52–enable-liba52bin–enable-pp–enable-libfaad–enable-libfaadbin–enable-libfaac–enable-pthreads–disable-ffserver–enable-x11grab
    如果报错则安装该包,或者直接去掉该参数,只需要配置自己使用过程中需要使用到的就行了。
    make & make install
    其他的则一个一个的下载解压在编译就是了。
  6. 具体参考本文:centos+zendce+red5+ffmpeg安装配置
  • 下面是php-ffmpeg 使用的api。功能是很少了。
  • 如果需要给视频抓图择需要使用shell脚本。也就是用到php当中的(system,exec,passthru)这类执行外部命令函数。
    往往很多服务器都将种类函数视为危险函数屏蔽掉了。所以想做视频网站对服务器的配置要求比较高。
    当然最好是自己的独立服务器。vps 也可以。随便你怎么整都可以。

$movie->getBitRate()  Return the bit rate of the movie or audio file in bits per second.
$movie->getVideoBitRate()  Return the bit rate of the video in bits per second.
NOTE: This only works for files with constant bit rate.
$movie->getAudioBitRate()  Return the audio bit rate of the media file in bits per second.
$movie->getAudioSampleRate()  Return the audio sample rate of the media file in bits per second.
$movie->getFrameNumber()  Return the current frame index.
$movie->getVideoCodec()  Return the name of the video codec used to encode this movie as a string.
$movie->getAudioCodec()  Return the name of the audio codec used to encode this movie as a string.
$movie->getAudioChannels()  Return the number of audio channels in this movie as an integer.
$movie->hasAudio()  Return boolean value indicating whether the movie has an audio stream.
$movie->hasVideo()  Return boolean value indicating whether the movie has a video stream.
$movie->getFrame([Integer framenumber])  Returns a frame from the movie as an ffmpeg_frame object. Returns false if the frame was not found.
framenumber - Frame from the movie to return. If no framenumber is specified, returns the next frame of the movie.
$movie->getNextKeyFrame()  Returns the next key frame from the movie as an ffmpeg_frame object. Returns false if the frame was not found.




测试用例:ffmpeg-execute.php
安装过程出现错误解决:
  1. make: *** [ffmpeg-php.loError 1
    解决:.编译时加上 (php-config)路径:
    --with-php-config=/usr/local/php/bin/php-config
  2. make: *** [ffmpeg_frame.lo] Error 1
    解决:mv ffmpeg_frame.loT ffmpeg_frame.lo
  3. 其他问题请检查自己的php版本。和php-ffmpeg是否一致。
