filter_complex

Bhikkhu Mettavihari
Greetings

I need a bit of help to understand how to use filter_complex
I have a video file where I need to insert a logo in the video file.

I have been suggested the following command

ffmpeg -y -threads 16 -i $FILE1.mp4 -i vidasa11.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 $FILE1.ts &> output.log &

when I run the command this is the output I get.

I would be sure all the text is in one line, e.g.

ffmpeg -y -threads 16 -i $FILE1.mp4 -i vidasa11.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 $FILE1.ts &> output.log &

or alternately paste this into the terminal:

ffmpeg -y -threads 16 -i $FILE1.mp4 -i vidasa11.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 $FILE1.ts &> output.log &

ok?

-or alternately paste this into the terminal:

ffmpeg -y -threads 16 -i $FILE1.mp4 -i vidasa11.png -filter_complex  \
[1:v]scale=100:-1[logo]; "[0:v]scale=720:576[vid];"  \

ok?

My script is on one line BUT one never knows :-)
Just to make sure I copied your part into my script file and got the same result

Input #1, png_pipe, from 'vidasa11.png':
Duration: N/A, bitrate: N/A
Stream #1:0: Video: png, rgba(pc), 360x270, 25 tbr, 25 tbn, 25 tbc
Filter scale has a unconnected output

It looks like it is at the "filter scale"

But I am not so sure about it.
I tried one of the simplest commands

ffmpeg –i video.mp4 -i logo.png -filter_complex "overlay=10:10" top_left.mp4

and got this error.

Input #0, png_pipe, from 'logo.png':
  Duration: N/A, bitrate: N/A
    Stream #0:0: Video: png, rgba(pc), 360x270, 25 tbr, 25 tbn, 25 tbc
Cannot find a matching stream for unlabeled input pad 1 on filter
Parsed_overlay_0

Re: filter_complex

Bhikkhu Mettavihari
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 &
