Ok, my first problem I resolved, but I receive a message after convert, this is:

this is first message

Cannot find HOME directory.
MPlayer svn r34540 (Ubuntu), built with gcc-4.6 (C) 2000-2012 MPlayer Team
Terminal type `unknown' is not defined.

this is to finally message

Running flvtool2: /usr/bin/flvtool2 -U /.../.../.../.../.../penticostal_es/flvideo/4ca4238a0b/1411018312427860559.flv
UPDATE `process_queue` SET `status`='6' WHERE `id`='182'
ERROR: failed video conversion.

How can I do to remediate this?
