ffmpeg

building ffmpeg from source may boost performance
known issue: the default TLS library (gnutls) that ships with ffmpeg causes an infinite loop. building with OpenSSL fixes that issue. running with jemalloc helps with memory leaks

before installing, make sure ffmpeg and its libraries are not already on the machine
by uninstalling all libav*-dev and libav* packages and deleting any manual installations of ffmpeg and its libraries to avoid issues

apt install pkg-config libssl-dev libmp3lame-dev libopus-dev libvorbis-dev nasm

git clone --depth 1 https://github.com/FFmpeg/FFmpeg
cd FFmpeg
./configure --arch=amd64 --disable-stripping --enable-openssl --enable-libmp3lame --enable-libopus --enable-libvorbis --enable-shared --enable-nonfree
make -j $(nproc)
make install
ldconfig

run with jemalloc

apt install libjemalloc-dev
