This repository hosts scripts and commands to build WebAssembly port of FFmpeg powering wide.video | Free Online Video Editor and ffmpeg.wide.video | FFmpeg Online.
Default build procedure using docker will produce multiple (gpl, lgpl, simd) artifacts in ./wasm folder:
./scripts/docker-run.sh
./scripts/docker-init.sh # execute in container shell
./scripts/release.sh # execute in container shellAlternatively, non-container build can be executed similarly:
sudo -s
./scripts/release.shRelease script further executes configuration and build of each submodule, which can be called manually as follows:
sudo -s
export FFMPEG_LGPL=true # release.sh
export FFMPEG_SKIP_LIBS=false # release.sh
./scripts/clean.sh # release.sh
./scripts/build.sh # release.sh
source scripts/init-emscripten.sh # build.sh
./scripts/build-zlib.sh # build.sh
./scripts/configure-ffmpeg.sh # build.sh
./scripts/build-ffmpeg.sh # build.sh
./scripts/customize-ffmpeg.sh # build.shReattach stdin for exited container:
docker ps -q -l # find container ID (or discover via Docker desktop)
docker start dd3dbe04a7e5 # restart in the background
docker attach dd3dbe04a7e5 # reattach the terminal & stdin- Google shell Encountered a section with no Package: header can be resolved by calling
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 467B942D3A79BD29 - Single thread version is not buildable as FFmpeg depends upon threading.
- Openh264 not buildable with emscripten >= 3.1.33
