FFMpeg在命令行中工作，但不在shell_exec中工作

Question

When I convert a video using command line(ffmpeg -i dust.mp4 -s 320x240 video.flv 2>&1) it does the conversion fine. But when I use the php code it does not. The code is as follows:

echo "Starting ffmpeg...

";
$ffmpeg = "~/ffmpeg_sources/ffmpeg";
echo exec("$ffmpeg  -i dust.mp4 -s 320x240 video.flv 2>&1");
echo "Done.
";

And the output is :

Starting ffmpeg... sh: 1: ~/ffmpeg_sources/ffmpeg: not foundDone.

Any help will be appreciated.

Thanks in advance
