after investigation of latest patch i found that problem comes from *mov:
Double-check that alias path is not an absolute path*
http://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=9286de045968ad456d4e752651eec22de5e89060
*alis* contains all information: absolute path, relative search
information. and yes, absolute path always contains slash
simple solution is just drop slash check

moreover, flag *-use_absolute_path 1* is a input format (mov) dependent.
i.e. if you need a simple thumbnail, you need to check if mov and only
then submit *-use_absolute_path 1* flag.
is it normal? i can fix it by setting this flag to 1 by default, but why
somebodies paranoia prevent ffmpeg from normal behavior?
