This only depends on your toolchain: If you don’t specify a compiler when calling configure the default system compiler will be used. On Intel 64bit systems, the system compiler most likely will default to 64bit. But this is not necessarily always the case, and on non-Intel 64bit systems it is common for the system compiler to default to 32bit. There is a configure option „--cc“ that you can use to force 32 or 64 bit compilation: ./configure --cc=gcc -m32 (Needs parentheses around gcc -m32!!)

[FFmpeg-user] Linux 64 bit ffmpeg compilation
Hi I have followed ffmpeg compilation guide " https://trac.ffmpeg.org/wiki/CompilationGuide/Centos; and its successful, would like to know FFmpeg is 64bit by default (or) should i need to enable any flags / properties. Also is there any ffmpeg tuning guide/recommendation? ffmpeg version 4.3 Copyright (c) 2000-2020 the FFmpeg developers built with gcc 8 (GCC) configuration: --prefix=/root/ffmpeg-4.3/ffmpeg_build --pkg-config-flags=--static --extra-cflags=-I/root/ffmpeg-4.3/ffmpeg_build/include --extra-ldflags=-L/root/ffmpeg-4.3/ffmpeg_build/lib --extra-libs=-lpthread --extra-libs=-lm --bindir=/root/ffmpeg-4.3/bin --enable-gpl --enable-libfdk_aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libvpx --enable-libx264 --enable-libx265 --enable-nonfree --enable-openssl libavutil 56. 51.100 / 56. 51.100 libavcodec 58. 91.100 / 58. 91.100 libavformat58. 45.100 / 58. 45.100 libavdevice58. 10.100 / 58. 10.100 libavfilter 7. 85.100 / 7. 85.100 libswscale 5. 7.100 / 5. 7.100 libswresample 3. 7.100 / 3. 7.100 libpostproc55. 7.100 / 55. 7.100 Hyper fast Audio and Video encoder usage: ffmpeg [options] [[infile options] -i infile]... {[outfile options] outfile}...
