Debian Buster 64bit If run ffmpeg from cmd line is ok, if change present in winff not work.... because?

No idea. Could you please copy/paste any output in the command window? Also, is this the winff package installed via Debian packages or did you compile yourself?

Oputput:

Option hwaccel (use HW accelerated decoding) cannot be applied to output url /home/michele/Video/test.mp4 -- you are trying to apply an input option to an output file or vice versa. Move this option before the file it belongs to. Error parsing options for output file /home/michele/Scrivania/test.mp4. Error opening output files: Invalid argument

If I remember correctly (it has been a while since I used WinFF myself) WinFF doesn't have the feature to add options the correct stream for this to work. Apparently the option you want here, needs to go in a different location on the command line that WinFF puts it. I don't think there's a way around this.

If I remember correctly, there is a wishlist bug open for this support.
