This is a libav wrapper for PHP. It may replace ffmpeg.

• PHP >= 5.3
• Not tested under Windows, might work

Install

> phpize
> ./configure
> make
> make install

Example

$r = av_file_open("/tmp/my_vid.avi");
var_dump(av_file_get_metadata($r));
/*array(4) {
["nb_streams"]=>
int(2)
["filename"]=>
string(12) "/tmp/vid.avi"
["duration"]=>

["bit_rate"]=>

var_dump(av_libav_get_info());
/*

Sure, WIP.

In the end, you should be able to do what libav can do, in PHP.

Conversions, resampling etc.. Consult libav manual for features http://libav.org/documentation.html.

• Bridges to ext/gd may also be developed.
• Bridges with PHP stream layer may as well be developed in future.
