[FFmpeg-user] filter_complex

[Mettavihari D]

Greetings all,

The Problem is solved.
It was only a problem of the correct hyphens around the object

 '0:a’ should be '0:a'

ffmpeg -y -threads 16 -i video.mp4 -i logo.png -filter_complex
"[1:v]scale=100:-1[logo];[0:v]scale=720:576[vid];[vid][logo]overlay=590:40[out]"
-map '[out]' -map '0:a' -preset slower -profile:v main -level 3.1 -c:v
libx264 -g 24 -bf 3 -b_strategy 2 -coder 1 -r 25000/1000 -b:v 1650k
-maxrate:v 1650k -minrate:v 1650k -bufsize:v 330k -flags +ilme+ildct
-x264opts bff=1 -color_primaries 1 -color_trc 1 -colorspace 1 -c:a mp2
-b:a 128k -nal-hrd cbr -muxrate 1900k -f mpegts output-10.ts &>
output-10.log &
