How to parse ffmpeg info in PHP?

Question

How does one go about getting specific pieces of information, like the \'duration\' from the output of ffmpeg -i /var/thismovie.avi ?

I need frame heigh

Answer 1

$output = `ffmpeg -i /var/thismovie.avi`; //note that back quote is like exec
preg_match('/Duration: (.*?),.*?Video:.*?0x.*?([0-9]+)x([[0-9]+).*?([0-9]+) fps/i'
    ,$output , $result);

output of $result array should be like this:

Array
(
    [0] => Duration: 00:00:10.76, start: 0.000000, bitrate: 5180 kb/s Stream #0:0: Video: h264 (High) (H264 / 0x34363248), yuv420p, 1280x720 [SAR 1:1 DAR 16:9], 25 fps
    [1] => 00:00:10.76
    [2] => 1280
    [3] => 720
    [4] => 25
)

UPDATE

The actual output is multi line, so please update the pattern into

/Duration: (.*?),.*?([0-9]+)x([0-9]+) \[.*?([0-9]+) fps/is
