###Build FFmpeg under Unix for Windows (x86) 32bit and 64bit
This script is going to build a shared version of ffmpeg that does not have any dependencies, i.e: all dependencies are linked statically.
This is expected that you have installed MXE http://mxe.cc and cloned their git repository somewhere. We will reference that git repository root in the script build-ffmpeg.sh by the variable MXE_PATH.
The first time you install MXE you must create a file settings.mk as such:
cd mxe
echo "MXE_TARGETS := x86_64-w64-mingw32.static i686-w64-mingw32.static" > settings.mk
On the first install you will be probably missing most of dependencies, so you should try installing the ffmpeg package provided by MXE itself. We will build our own afterwards because MXE will build a static version of ffmpeg (libav*.a). #You are in mxe/ make ffmpeg
Now ffmpeg static is assumed to be installed via MXE.
Open build-ffmpeg.sh and edit the customizable options to setup the remote server where to upload and get third party sources. Optionally you can change the dependencies and ffmpeg version.
Now just type:
export MXE_PATH=...
env NO_UPLOAD=1 MKJOBS=8 sh build-all.sh
This will build 4 variants of ffmpeg: 64bit-Gplv2 64bit-LGPL 32bit-GPLv2 32bit-LGPL.
Alternatively you can build only one of them by using:
export MXE_PATH=...
env NO_MXE_PKG=1 MKJOBS=8 NO_UPLOAD=1 BITS=64 sh build-ffmpeg.sh || exit 1
If you want your script to automatically upload the build on to some remote location, you can specify a remote user and host in a file named local.sh next to the build-ffmpeg.sh script. The file should be as such:
#!/bin/sh
#This is the URL to where the required third party sources are located
THIRD_PARTY_SRC_URL=...
#This is the name of the user that will be used to upload the build
REMOTE_USER=...
#This is the address of the host
REMOTE_HOST=...
#This is the location on the host where to upload the files
REMOTE_HOST_PATH=...
