I can now reproduce the problem:
It works here for avi (at least with some players)
in the sense as it changes aspect just like the
original transport stream does but for mov the global
aspect "wins" and the filter chain - afaict - does
not allow to switch parameters frame-wise (which
would be necessary for changing pad afaict).
I would like to wait for a comment from one of the
filter experts but this will probably be an enhancement
request. (without eta...)
Thank you for the report, Carl Eugen
