[MEncoder-users] PHP cannot execute some encoding commands

[Tushar Bhatnagar]

Hello,

You need to make sure that the permissions are set to 0666 for the
video device that you are capturing from.  Also, you need to make sure
that the place you are writing the output directory to also has read
and write permissions for anyone.  Hopefully that solves the problem.
