The behaviour is based on assumptions:
- copying audio data is cheap, so keeping data alignment is cheap,
- copying video data is not cheap, so keeping data alignment is not cheap,
e.g. crop filter.
Should fix Ticket6349.
Note that after fc3a03fcf9cd7eafe7342e2508e6128888efa0bb, the crash has
been fixed.
