misbehaviour of ``afade`` chained with ``amovie``

Reported by: while0pass Owned by:
Priority: normal Component: avfilter
Version: git-master Keywords: amovie afade
Cc: Blocked By:
Blocking: Reproduced by developer: yes
Analyzed by developer: no

Description

afade=t=in... chained with amovie changes nothing, afade=t=out... chained with amovie makes stream completely silient. Both issues seem valid only for amovie source and not for -i option source where everything is ok.

$ ffmpeg -y -filter_complex 'amovie=/home/nurono/Desktop/kmvso.mp3, atrim=start=0:end=10, afade=t=in:st=0:d=2' n1.mp3

The output file is not silent if the intermediate file is a wav file or the original mov.

If ac3 is used as intermediate format, the effect is even worse: The output file starts loud and gets silent after two seconds.
