FFMPEG works in command line but not in exec(&

Question

The command is

ffmpeg -i path/to/video.avi path/to/video.mpg

and it works fine from the command line. However, when I call it with PHPs exec(), the return value is 127, it doesn't seem to detect FFMPEG. What am I doing wrong? I'm in localhost and the safe mode is off, but I'm new to both FFMPEG and exec(), so it may be a noob mistake. Thanks in advance.

Answer 1

Try

exec(/path/to/ffmpeg -i path/to/video.avi path/to/video.mpg);

Answer 2

did you register your ffmpeg command as a PATH Environment variable in Linux / Windows ???? it seems that you did not set it as a PATH variable that's why you have to include full path to FFMPEG command so that it worked for you.
