[FFmpeg-user] insert a logo with transparency

[Rossana Guerra]

Well I installed the FFmpeg version for Ubuntu 12.04 (not the fork, the
"actual")

Now it seems I have problems to insert logo, there's a syntax error, I
can't realize what according to FFmpeg documentation.
I appreciate any help.

Thanks

Rossana
