Thanks for warning. Anyway this can never happen to me cause all video
files I broadcast are in PAL format
in one DV/Avi format from one DV encoder. I need seamless output so this
is the only way to reach it.
I noticed this (what you write about) when I was playing with mixed
It makes awfull blackouts between files in different format, because all
the filters and output are
recreated. I hope I'll avoid this by using VLM/mosaic in the future.
In fact I'll have to do both what you've written anyway, because just
after creating the filter the callback
function isn't called, which means I can't react on the name of first
file in playlist. By initializing the name
in init I'll solve this and it will work when the filter recreates.
