How to read information from .3gp and .mp4 using ffmpeg-php?

Question

I have a bit of a problem with ffmpeg-php. I'm trying to get some information from video files and it works pretty fine with file formats like .avi, .mpg or .flv but when I try to use .3gp or .mp4 in:

$movie = new ffmpeg_movie('path/to/file/test.3gp');

I get error like this :

ffmpeg_movie::__construct() []: ISO: File Type Major Brand: 3gp5 

or

ffmpeg_movie::__construct() []: ISO: File Type Major Brand: mp42 

I installed ffmpeg-php on WAMP using instructions found here: How to install FFMpeg in WampServer 2.0 (Windows XP)

I need those information to send them to ffmpeg using exec(). Anyone could help me with this?

Answer 1

You could also use a pure php approach using PHP media reader

Answer 2

While installing ffmpeg plugin on server, Mostly we will be having "ffprobe" library with it. By using ffprobe, we can get details/metadata about videos.

$ffprobe_path="ffprobe"; //path to installation of ffprobe
$video_file="/home/testsite/public_html/videos/mytest_video.mp4"; //path to the specific video file

$ffprobe_cmd=$ffprobe_path." -v quiet -print_format json -show_format -show_streams ".$video_file;  
$outputprobe = shell_exec($ffprobe_cmd);  
$result_video_meta = json_decode($outputprobe);
echo "<pre>";
print_r($result_video_meta);
echo "</pre>";
