PHP using php5-ffmpeg to capture video image instances, a few days ago when playing FFmpeg, suddenly found that Ubuntu with more php5-ffmpeg this expansion kit, I want to play to see, optimistic about the use of php5-ffmpeg in PHP to capture video image instances,

A few days ago when playing FFmpeg, suddenly found that Ubuntu more php5-ffmpeg expansion kit, I want to play to see, optimistic about the bad use, there are two conclusions:
Reading a video depends on FFmpeg's support. if you want to support all formats, we recommend that you recompile FFmpeg.
Efficiency is not as fast as I think. ten images are taken for two minutes, about 30 seconds.
Installation method:

The code is as follows:

Sudo apt-get install ffmpeg php5-ffmpeg php5-gd

Example of a pie chart test:

The code is as follows:

<? Php
$ Page = 10;
$ Prefix = 'screencap ';

$ Mov = new ffmpeg_movie ('GT. avi ');
$ Count = $ mov-> getFrameCount ();
$ Range = (int) round ($ count/($ page + 1 ));

For ($ I = 1; $ I <= $ page; $ I ++ ){
$ FrameNum = $ range * $ I;
$ ImgFile = paiprefix.'_'.baii.'.png ';

$ Frame = $ mov-> getFrame ($ frameNum );
If (! $ Frame) {continue ;}

$ GdImage = $ frame-> toGDImage ();
If (! $ GdImage) {continue ;}

Imagepng ($ gdImage, $ imgFile );
Imagedestroy ($ gdImage );

Echo'

}
