Check the supported formats:


ffmpeg -format

Test converting videos. Here’s an example from mp4 to h264:


cd /usr/local/src
wget https://archive.org/download/WoodstockFestivalTrailer/Woodstock_Festival_Trailer.avi
ffmpeg -i Woodstock_Festival_Trailer.avi -vcodec libx264 Woodstock_Festival_Trailer-H264.avi
After done, you should see the new H264 file:

-rw-r--r-- 1 root root 20M May 4 2006 Woodstock_Festival_Trailer.avi
-rw-r--r-- 1 root root 15M Jan 30 10:01 Woodstock_Festival_Trailer-H264.avi

How can I work with ffmpeg using PHP?

Simple. Just install php-ffmpeg extension. First, install REMI repo in order to get your php-ffmpeg package, then type:


yum install php-ffmpeg
Verify ffmpeg is loading from PHP:

php -i | grep ffmpeg -i

If you see this, it’s working:


[root@nginxtips.com:~]php -i | grep ffmpeg -i
/etc/php.d/ffmpeg.ini,
ffmpeg
ffmpeg-php version => 0.7.0
