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. ffmpeg version 2.8.15-0ubuntu0.16.04.1 Copyright (c) 2000-2018 the FFmpeg developers built with gcc 5.4.0 (Ubuntu 5.4.0-6ubuntu1~16.04.10) 20160609 configuration: --prefix=/usr --extra-version=0ubuntu0.16.04.1 --build-suffix=-ffmpeg --toolchain=hardened --libdir=/usr/lib/x86_64-linux-gnu --incdir=/usr/include/x86_64-linux-gnu --cc=cc --cxx=g++ --enable-gpl --enable-shared --disable-stripping --disable-decoder=libopenjpeg --disable-decoder=libschroedinger --enable-avresample --enable-avisynth --enable-gnutls --enable-ladspa --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libflite --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libmodplug --enable-libmp3lame --enable-libopenjpeg --enable-libopus --enable-libpulse --enable-librtmp --enable-libschroedinger --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libtwolame --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx265 --enable-libxvid --enable-libzvbi --enable-openal --enable-opengl --enable-x11grab --enable-libdc1394 --enable-libiec61883 --enable-libzmq --enable-frei0r --enable-libx264 --enable-libopencv libavutil 54. 31.100 / 54. 31.100 libavcodec 56. 60.100 / 56. 60.100 libavformat 56. 40.101 / 56. 40.101 libavdevice 56. 4.100 / 56. 4.100 libavfilter 5. 40.101 / 5. 40.101 libavresample 2. 1. 0 / 2. 1. 0 libswscale 3. 1.101 / 3. 1.101 libswresample 1. 2.101 / 1. 2.101 libpostproc 53. 3.100 / 53. 3.100 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'sinhala-09-04-03-512k.mp4': Metadata: major_brand : isom minor_version : 512 compatible_brands: isomiso2avc1mp41 encoder : Lavf54.3.100 Duration: 00:27:35.18, start: 0.000000, bitrate: 641 kb/s Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 720x576 [SAR 16:15 DAR 4:3], 507 kb/s, 25 fps, 25 tbr, 25 tbn, 50 tbc (default) Metadata: handler_name : VideoHandler Stream #0:1(und): Audio: aac (LC) (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 127 kb/s (default) Metadata: handler_name : SoundHandler 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 This is my log file. editor@Mettavihari:~/compress$ cat output.log ./logo-comp-10to11-V0.sh: line 24: [0:v]scale=720:576[vid];: command not found Any hint on corrections in the command is much appreciated. with metta Mettavihari _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
