running a exec() from php

[denoteone]

Trying to convert an avi into a flv using a phpscript and ffmpeg. Below is the most important part of my code but I am not able to convert yet.

 

$newname = myvideo.avi
  
define('FFMPEG_LIBRARY', '/usr/bin/ffmpeg ');

$exec_string = FFMPEG_LIBRARY.' -i /var/www/html/site/videos/day/upload/$newname  /var/www/html/site/videos/day/upload/outputfile.flv';

exec($exec_string); 

 

I have a video portal running so I am sure that I have ffmpeg installed correctly.

 

Any help would be great.

caught one of my own mistakes in the $exec_string variable.

 

		  define('FFMPEG_LIBRARY', '/usr/bin/ffmpeg ');

	  $exec_string = FFMPEG_LIBRARY.' -i '. $newname .' -ab 56 -ar 44100 -b 200 -r 15 -s 320x240 -f flv video_finale.flv';

	   echo $exec_string;

	  exec($exec_string);

 

But still not working.

I had a similar problem when calling mysqldump via the exec command last week. My problem was wrapping all variables in single quotes. If your variable content (ie. the new filename) has a space in it, the command would be parsed incorrectly. Have you tried running the command directly via the Terminal? If so, what error did you get?
