[FFmpeg-user] feature proposal - avoid overwriting the input file

[Mikhail V]

Currently it is possible to delete the input file if I specify same
filename in output,
for example:

ffmpeg -y -i input input

or simply:
ffmpeg -i input input
(this will promt y/n)

So this will immideately destroy the input file.
It did not happened with me often, but still happened a pair of times.
Was quite funny actually :) Funniest thing that I could not recover the file
because it is same name.

So, it would be nice if ffmpeg compare the output path with all input paths
and exit with an error.
