[FFmpeg-user] fade filter crashes ffmpeg

[Michael Koch]

Hi all,

I just tried this command line and it crashes FFmpeg:

ffmpeg -i meteor308.mp4 -vf fade=in:0:0.5 -q:v 1 -y 308.mp4

I already know what's wrong. I thought the fade duration is expressed in 
seconds. But (with this syntax) it must be expressed in frames and must 
be an integer. It would be nice to get an error message instead of a crash.
