Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...) -

ffmpeg minimal linux build with only one filter [closed]
31 juillet 2024, par at8993I am aiming to compile a minimal build of ffmpeg for Ubuntu 22.04. The application requires only the concat filter for .mp4s using H.264 video encoder.


I have followed this guide and used the following commands to include libx264 only :


sudo apt-get update -qq && sudo apt-get -y install \
 autoconf \
 automake \
 build-essential \
 cmake \
 git-core \
 libass-dev \
 libfreetype6-dev \
 libgnutls28-dev \
 libmp3lame-dev \
 libsdl2-dev \
 libtool \
 libva-dev \
 libvdpau-dev \
 libvorbis-dev \
 libxcb1-dev \
 libxcb-shm0-dev \
 libxcb-xfixes0-dev \
 meson \
 ninja-build \
 pkg-config \
 texinfo \
 wget \
 yasm \
 zlib1g-dev

mkdir -p ~/ffmpeg_sources ~/bin

sudo apt-get install libx264-dev



and for the configure command I have used the following options with a view to only enable what's necessary for concat.


cd ~/ffmpeg_sources && \
wget -O ffmpeg-snapshot.tar.bz2 https://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2 && \
tar xjvf ffmpeg-snapshot.tar.bz2 && \
cd ffmpeg && \

PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure \
 --prefix="$HOME/ffmpeg_build" \
 --pkg-config-flags="--static" \
 --extra-cflags="-I$HOME/ffmpeg_build/include" \
 --extra-ldflags="-L$HOME/ffmpeg_build/lib" \
 --extra-libs="-lpthread -lm" \
 --ld="g++" \
 --bindir="$HOME/bin" \
 --disable-everything \
 --enable-filter=concat \
 --enable-avformat \
 --enable-avdevice \
 --enable-avcodec \
 --enable-decoder=h264 
 --enable-libx264 
 --enable-muxer=mp4 
 --enable-gpl

PATH="$HOME/bin:$PATH" make && \
make install && \
hash -r



However running


ffmpeg -f concat -i files_to_merge.txt -c copy output.mp4



returns error


ffmpeg -f concat -i files_to_merge.txt -c copy output.mp4

I assume this is due to the omission of an enable option in the configure command.


Thanks !

The B extension was finally ratified in May 2024, encompassing :
Zba (addresses),
Zbb (basics) and
Zbs (single bits).
It does not include Zbc (base-2 polynomials).
