I'm using vfilters for overlaying 2 video (in fact 2 streams of the same video file). Everythink is ok.
I now want to delay the start to make a "thumbnail" of 20s at 180s from the start.
I add -ss 180 to the command line and ":seek_point=180" option to movie filter:

./ffmpeg -i /media/video.avi -map 0.0 -map 0.2 -ss 180 -t 20 -y -deinterlace -s 720x576 -vf "movie=/media/video.avi:stream_index=1:seek_point=180, scale=240:192 [vueint];[in][vueint] overlay=440:352 [out]" -target pal-dvd -b 4194304 out.mpg

ffmpeg doesn't complain, but in the final output, the main stream is ok but the overlay stream still start at 0. I've tried changing the movie filter options order without success.
I've just downloaded the last version (0.8). No changes.

Any idea ?
