blocks|key|5621943|text|我曾经遇到过类似的问题，但我选择了在apache可写文件夹中保存和读取文件(输入文件和输出转换文件)，您也可以通过读取该目录来检查转换是否已经完成。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5621944|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I had a similar problem once but i've choose to save and read files (input file and output converted file) in a apache writable folder
You can also check if convertion is alredy done via reading that directory.

blocks|key|657526|text|你能在PHP上检查你的disabled_functions配置，看看是否没有exec吗？此外，您可能希望启用所有error+reporting，然后尝试使用一个简单的bash回显来执行exec()，看看效果如何。如果一切正常，那么检查你是否使用了正确的文件，正如Jamie所指出的，工作目录可能是错误的，所以使用绝对路径或相对路径，无论是最方便的。用于检查当前工作目录的Unix命令是pwd。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|657527|编辑：另外，exec还有另一个警告When+safe+mode+is+enabled,+you+can+only+execute+files+within+the+safe_mode_exec_dir，所以一定要好好阅读manual上的其他问题。|BOLD|657528|entityMap|0|LINK|mutability|MUTABLE|url|http://www.php.net/manual/en/function.error-reporting.php|1|http://www.php.net/manual/en/function.exec.php|2^0|5C|3|1K|F|0|0|0|3|H|2B|6|4|1|32|6|2|0^^$0|@$1|2|3|4|5|6|7|T|8|@$9|U|A|V|B|C]]|D|@$9|W|A|X|1|Y]]|E|$]]|$1|F|3|G|5|6|7|Z|8|@$9|10|A|11|B|H]|$9|12|A|13|B|C]]|D|@$9|14|A|15|1|16]|$9|17|A|18|1|19]]|E|$]]|$1|I|3|-4|5|6|7|1A|8|@]|D|@]|E|$]]]|J|$K|$5|L|M|N|E|$O|P]]|Q|$5|L|M|N|E|$O|R]]|S|$5|L|M|N|E|$O|R]]]]

Can you check your disabled_functions configuration on PHP and see if exec is not there? Also you might want to enable all <a href="http://www.php.net/manual/en/function.error-reporting.php" rel="nofollow">error reporting</a> and after try to exec() with a simple bash echo and see how it goes. If all goes well then check if you are using the correct files, as Jamie pointed out, the working directory might be the wrong one so use absolute paths or relative, whatever is most convenient. The Unix command for checking what is the current working directory is <code>pwd</code>.

Edit: Also, <a href="http://www.php.net/manual/en/function.exec.php" rel="nofollow">exec</a> has another caveat <code>When safe mode is enabled, you can only execute files within the safe_mode_exec_dir</code> so be sure to have a good read on the <a href="http://www.php.net/manual/en/function.exec.php" rel="nofollow">manual</a> for other problems.

blocks|key|5137743|text|有趣的是，你想在它自己的进程中执行它，并在后台中执行，否则你的PHP脚本将在等待转换完成的过程中挂起。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|5137744|代码：|5137745|passthru("nohup+/usr/local/bin/ffmpeg+-i+1.mp4+-vcodec+libtheora+-acodec+libvorbistestjohn4545454.ogg+1>+/path/to/logfile.txt+2>&1+&");|CODE|5137746|请注意"nohup“和末尾的”&“符号:它们应该能满足您的需求。此外，您现在可以定期检查您的日志文件，以确保它正在执行您想要的操作。|5137747|最后，如果您愿意，可以查看this+question来创建进度条。|5137748|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/questions/11441517/ffmpeg-progress-bar-encoding-percentage-in-php^0|Q|P|0|0|3|0|0|3R|0|3R|0|0|1U|0|0|X|D|D|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@$9|X|A|Y|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|Z|8|@$9|10|A|11|B|C]]|D|@]|E|$]]|$1|H|3|I|5|6|7|12|8|@$9|13|A|14|B|C]|$9|15|A|16|B|J]]|D|@]|E|$]]|$1|K|3|L|5|6|7|17|8|@$9|18|A|19|B|C]]|D|@]|E|$]]|$1|M|3|N|5|6|7|1A|8|@$9|1B|A|1C|B|C]]|D|@$9|1D|A|1E|1|1F]]|E|$]]|$1|O|3|-4|5|6|7|1G|8|@]|D|@]|E|$]]]|P|$Q|$5|R|S|T|E|$U|V]]]]

Funny thing here, you want to execute this in it's own process and in the background, otherwise your PHP script will hang whilst waiting for the conversion to complete.

The code:

<code>passthru("nohup /usr/local/bin/ffmpeg -i 1.mp4 -vcodec libtheora -acodec libvorbistestjohn4545454.ogg 1&gt; /path/to/logfile.txt 2&gt;&amp;1 &amp;");</code>

Note the "nohup" and the ampersand on the end: these should give you what you require. Also, you can now check your logfile periodically to make sure that it's doing what you want.

And finally, check out <a href="https://stackoverflow.com/questions/11441517/ffmpeg-progress-bar-encoding-percentage-in-php">this question</a> for creating a progress bar, if you like.

blocks|key|1787853|text|感谢您的回复。我使用passthru()而不是exec()，它工作得很好。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1787854|entityMap^0|A|A|N|6|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

Thank you for the replies. I used <code>passthru()</code> instead of <code>exec()</code> and it works fine.

I want to convert mp3 file to ogg. I tried the following code

<pre><code>exec("/usr/local/bin/ffmpeg -i 1.mp4 -vcodec libtheora -acodec libvorbis testjohn4545454.ogg",$output);
var_dump($output);
</code></pre>

But it does not convert the file and it only returns <code>array(0) { }</code>
and it only takes a little execution time.

But the conversion is success when using ssh command.

Please give me solution.
