How to compile a static FFmpeg binary on OS X
29 juillet 2014, par Chitanda_EruI want to compile a static ffmpeg binary by myself. I follow this guide, and then built one successfully.
./configure --extra-version=Chitanda_Eru --prefix=/Volumes/Chitanda_Eru/ --enable-gpl --enable-version3 --enable-nonfree --disable-shared --enable-static --enable-ffplay --disable-ffserver --enable-pthreads --enable-avisynth --enable-libvo-aacenc --enable-libfaac --enable-libfdk-aac --enable-libmp3lame --enable-libvorbis --enable-libx264 --enable-libx265 --enable-libxvid --enable-libbluray --enable-libtheora --enable-libcelt --enable-openssl --enable-libspeex --enable-postproc --enable-libvpx --enable-libgsm --enable-libopenjpeg --enable-libopus --enable-fontconfig --enable-libfreetype --enable-libass --enable-filters --disable-indev=qtkit --enable-runtime-cpudetect --enable-bzlib --enable-zlib --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libvo-amrwbenc --enable-libtwolame --enable-openal --enable-libsoxr --enable-libwavpack --enable-libvidstab --enable-libilbc --enable-libschroedinger --enable-libcaca --enable-opengl --enable-frei0r --enable-libquvi
But I come across a problem, the FFmpeg binary is only 15.5MB which is much smaller than the official builds, what’s more, it can’t work on my second Mac and with errors below.

update : I successfully build static ffmpeg after moving all the dylibs which have static libraries as well to other dictionary and disable all the libraries that ./configure can’t find.

Mix additional audio file with video(+audio) in ffmpeg
21 mai 2019, par SergI’m trying to mix additional audio file with video which has also audio within. But the problem is that I already have complex ffmpeg command and don’t know how to combine them together.
This is my existing ffmpeg command which uses some offsets and replaces additional audio file with embedded one (audio inside video) and also overlays few gauges and watermark to the video.
ffmpeg -y
-ss 00:00:01:213 -i videoFile.mp4
-ss 00:00:03:435 -i audioFile.wav
-i watermark.png

-map 0:v -map 1:a -c:v libx264 -preset ultrafast -crf 23 -t 00:5:10:000 output.mp4Now I would like to use
ffmpeg's amix
in order to mix both audios instead of replacing them, if possible with ability to set volumes. But official documentation amix says nothing about volume.Separately both seems to work ok.
ffmpeg -y -i video.mp4 -i audio.mp3 -filter_complex [0][1]amix=inputs=2[a] -map 0:v -map [a] -c:v copy output.mp4
and
ffmpeg -y -i video.mp4 -i audio.mp3 -i watermark.png -filter_complex [0][2]overlay=(21):(H-h-21)[ovr0] -map [ovr0]:v -map 1:a -c:v libx264 -preset ultrafast -crf 23 output.mp4
but together
ffmpeg -y -i video.mp4 -i audio.mp3 -i watermark.png -filter_complex [0][1]amix=inputs=2[a];[a][2]overlay=(21):(H-h-21)[ovr0] -map [ovr0]:v -map [a] -c:v libx264 -preset ultrafast -crf 23 output.mp4
I’m getting an error :
