[FFmpeg-devel] [PATCH 0/3] concat demuxer: enhance interaction with lavfi

First patch allows using something like this as concat demuxer input

ffconcat version 1.1
file color=color=white,drawtext=text=TEST:fontsize=50:fontfile=/usr/share/fonts/corefonts/verdana.ttf:fontcolor_expr=random
format lavfi

Second patch allows to set duration (without this, lavfi would supply frames endlessly).

Andrey Utkin (3):
  concatdec: allow to set explicitly file input format
  concatdec: add force_duration option
  concatdec: update doc
