HomeBackend DevelopmentPHP Tutorial[急求]ubuntu下使用php调用ffmpeg转换视频格式、抽帧、摄像头实时录入不成功,是php设置问题?还是代码的问题?

我是按照http://blog.sina.com.cn/s/blog_568f35c701016tzb.html上的方法安装的LAMP,然后又按照http://dsec.pku.edu.cn/~lyj/Programming/configure_php.html上说的修改了一下
这个是转换视频的php代码,test.avi放在主文件夹目录里,直接用终端输ffmpeg -i test.avi outtest.asf能正常转换格式
$cmd="ffmpeg -i test.avi outtest.asf"; 
exec($cmd,$out,$status);
print_r($out);
print_r($status);//0是成功 1是失败
?>
在火狐里测试的时候就一直显示1表示失败,求大神们帮个忙!到底是哪里出问题了?急求!!!
是php设置有问题么?怎么设置才能让这些功能实现?

大神们,上面的问题我解决了,但是又出现新问题,我换了个代码
//$str='ffmpeg -i /tmp/test1.avi /tmp/out.ogv';
//$str='ffmpeg -i /tmp/test1.avi -y -f image2 -t 0.001 -s 352x240 /tmp/jt.jpg';
//$str='ffmpeg -i /tmp/test1.avi -r 1 -s 320x240 -f image2 /tmp/foo-%03d.jpeg';
//$str='ffmpeg -f image2 -i /tmp/foo-%03d.jpeg -r 12 -s 320x240 /tmp/foo.avi';
$str='ffmpeg -f video4linux2 -t 20 -s 320*240 -r 10 -i /dev/video0  /tmp/te.ogv';
$result=system($str);
?>
注释掉的部分都实现了,但是$str='ffmpeg -f video4linux2 -t 20 -s 320*240 -r 10 -i /dev/video0  /tmp/te.ogv';就是实现摄像头视频录入的功能无法实现,代码直接在终端里能实现,求问怎么解决!!!

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
