Hi Gianluca,

I was taking a look at this class and I was unable to get this to work from my localhost. I am using a windows machine and I was wondering if there are some details you need to take into consideration before using this class?

I have installed mediaInfo on my machine and I have completed the basic setup and it runs fine if I run the executable file separately. However if i run the script the variable mediainfo within the construct function always defaults to empty resulting in header 'mediainfo not available'.

Do you have to be running Debian or Ubuntu in order for this to work?

Many Thanks

Darren Conyard

Hi,
I use xubuntu. Call de mediainfo inside windows with the whole path. Maybe is that the problem

Hi Gianluca,

Thanks for getting back to me, So far I have tried shell_exec() with type -p and with the relative file path '../../../../../MediaInfo/MediaInfo.exe' and also with absolute file path. Within the command prompt I am able to write type mediainfo.exe and the contents of the file are displayed but within command prompt the text displayed does not make sense probably because it cannot interpret the .exe file correctly.

I think I have a hit brick wall with this. I think I am trying to make it compatible with windows and maybe that is not the case. Any help with this would be appreciated.

Darren

Hi,
i've got it working. I've downloaded the MediaInfo CLI library (no GUI) and putted in a folder on the htdocs

I put here below what I think you have to put attention:

// give here your own video/movie file
// this resides in the folder of the MediaInfo library
$mi = new mediaInfo('C:\xampp\htdocs\web\MediaInfo\sample-053.mkv');

// checks if library works (set your path to library)
$mediainfo = shell_exec('type -P C:\xampp\htdocs\web\MediaInfo\MediaInfo.exe');

// call the library with the filename this way (of course you have to set your path to the library)
$this->media_data = shell_exec("C:\\xampp\\htdocs\\web\\mediainfo\\MediaInfo.exe {$this->filename}");

AND THIS IS THE OUTPUT:
