calling mplayer -identify via php script?

bai_design · 01-27-2005, 09:29 AM

Is it possbile to call mplayer thorugh a php script?
The code I had been using is this:

Code:

$mplayer = "/usr/local/bin/mplayer -vo null -ao null -frames 0 -identify  ";
//echo "<br>Appended File:".$mplayer.$videoPath.$videofile;
$final = $mplayer."'".$videoPath.$videofile."'";
echo "<br>Final Command:".$final."<br>";
echo "<pre>";
echo $shell = system($final)."</pre>";

All information is being posted to the script from an HTML file...
I try running it this way but I keep on getting this feed pack from mplayer:

Code:

Final Command:/usr/local/bin/mplayer -vo null -ao null -frames 0 -nosound -identify '/home/jeremiah/testVideo/test.mkv'

If I run the same command in the commandline I get desired output. Is there something that I am missing that is preventing me from achieving this?
Also is it possible to do threading in php?

looks fine, what's an mkv file though? does it actaully play normally? what heppens if you run that mplayer command by itself?

When I execute it in the commandline I get this:

MKV/MKA is mastroka. Its a file container format for video/audio and I believe subtitles...

well it certainly knows what file it's meant to be playing... i'd be thinking along the lines of output streams... presumably in the php script you're only looking at stdout, and not stderr? i wouldn't have thought the -identify data would be going to stderr, but i do this exact same thing inside my dvd ripper, acidrip (perl) and i habitually redirect stderr back into stdout in the command line.

bai_design · 01-27-2005, 10:53 AM

so how exactly would I capture the stderr output then?
Is there a tutorial that you can refer me too?

acid_kewpie · 01-27-2005, 11:42 AM

just use "mplayer -opts file.mkv 2>&1" and both streams should appear.

bai_design · 01-27-2005, 01:31 PM

mplayer doesn't recognise the -opts option...
its listed as an unknown command...

acid_kewpie · 01-27-2005, 01:32 PM

it was an example... it implies "put all your option crap here"

bai_design · 01-27-2005, 01:37 PM

O... well it still returns with:

Code:
