[FFmpeg-user] Usages about multi outputs

Thanks Moritz,

Below are the all outputs. Maybe one filter_complex can feed all filters, but I do not have much experience about how to make it.

[root at cdn ffmpeg_dev]# ./ffmpeg -input.mp4 -i logo.png -filter_complex "yadif=deint=1,subtitles=subtitle.ass,delogo=x=60:y=60:w=100:h=77:band=10,overlay=10:10,split=2[a][b]" -map "[a]" -map 0:a -filter_complex scale=640:-1:sws_flags=lanczos -pass 1 -vcodec libx264 -r 25 -b:v 230k -profile:v high -c:a libfdk_aac -b:a 64k -ar 44100 -profile:a aac_he output1.mp4 -map "[b]" -map 0:a -filter_complex scale=960:-1:sws_flags=lanczos -pass 1 -vcodec libx264 -r 25 -b:v 550k -profile:v high -c:a libfdk_aac -b:a 64k -ar 44100 -profile:a aac_he output2.mp4 ffmpeg version 2.5 Copyright (c) 2000-2014 the FFmpeg developers

Please post the complete, uncut output from your command. For debugging
filter chains, it helps to add "-loglevel debug", so please also add
that.
 
The issue is probably that you cannot specify more than one
"-filter_complex" (I think). You should be able to specify your
complete filters for multiple outputs in one "-filter_complex".
