PHP上的FFMPEG和PHP不工作 [英] FFMPEG and PHP on mac does`t work

问题描述

我需要你的帮助。目前我使用Mac OS X 10.9.4和xampp apache 1.8.3-3。我需要使用ffmpeg（3.2版）通过php exec（）转换视频文件，但我无法使其工作。我做了一些运行终端命令行的测试，系统运行正常。只有在php它不工作。
ffmpeg是通过brew编译和安装的。

我运行了以下测试：

  exec（/ usr /local/Cellar/ffmpeg/2.3/bin/ffmpeg -i /Applications/XAMPP/xamppfiles/htdocs/teste/trailer.mp4 /Applications/XAMPP/xamppfiles/htdocs/teste/trailer2.flv 2>& 1，$ o，$ v）; 
 var_dump（$ o）; 
 var_dump（$ v）; 
  

并得到以下内容：

  array（4）{
 [0] => string（51）dyld：找不到符号：__cg_jpeg_resync_to_restart
 [1] => string（82）引用自：/System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO
 [2] => string（63）Expected in：/Applications/XAMPP/xamppfiles/lib/libJPEG.dylib
 [3] => string（67）in /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO} int（133）
  

解决方案

问题链接到DYLD_LIBRARY_PATH设置为xampp库文件夹

尝试在exec $ b之前取消设置$ b任何一个这样的exec将工作

  exec（'unset DYLD_LIBRARY_PATH;'）; 
 putenv（'DYLD_LIBRARY_PATH'）; 
 putenv（'DYLD_LIBRARY_PATH = / usr / bin'）; 
  

I need your help. Currently I use Mac OS X 10.9.4 and xampp apache 1.8.3-3. I need to use ffmpeg (version 3.2) to convert video files via php exec() but I cannot make it work. I did some testing running the terminal command line and the system operates normally. Only in php it doesn't work. ffmpeg was compiled and installed through the brew.

I ran the following test:

exec("/usr/local/Cellar/ffmpeg/2.3/bin/ffmpeg -i /Applications/XAMPP/xamppfiles/htdocs/teste/trailer.mp4 /Applications/XAMPP/xamppfiles/htdocs/teste/trailer2.flv 2>&1", $o, $v);
var_dump($o);
var_dump($v);

and got the following:

array(4) { 
    [0]=> string(51) "dyld: Symbol not found: __cg_jpeg_resync_to_restart" 
    [1]=> string(82) "Referenced from: /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO" 
    [2]=> string(63) "Expected in: /Applications/XAMPP/xamppfiles/lib/libJPEG.dylib" 
    [3]=> string(67) " in /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO" } int(133)

解决方案

problem is linked to DYLD_LIBRARY_PATH being set to xampp libraries folder

try unsetting this before exec any one of these before exec will work

exec('unset DYLD_LIBRARY_PATH ;');
putenv('DYLD_LIBRARY_PATH');
putenv('DYLD_LIBRARY_PATH=/usr/bin');
