*** Cross-compiling Avidemux on Linux for Windows ***
*** ***
*** Description of the default build environment setup ***
******************************************************************************
1. Install MXE (M cross environment) dependencies as described in
http://mxe.cc/#requirements
for your respective Linux distribution then clone the git repository as
described in
http://mxe.cc/#download
to /opt:
cd /opt
git clone https://github.com/mxe/mxe.git
(make /opt temporarily writable by the user or clone as root / using sudo).
Change the owner and the group of /opt/mxe to those of the user. In the
exemplary setup the 'mxe' folder has been subsequently moved elsewhere and
then bind-mounted to /opt/mxe to save write cycles of an SSD where /opt
resides. This has been done purely for convenience and is not required.
2. Create /opt/mxe/settings.mk with
MXE_TARGETS := i686-w64-mingw32.shared x86_64-w64-mingw32.shared
as content to build both 32 bit and 64 bit environments. Optionally, you can
set the variable MXE_TMP which determines where intermediate files are created
(e.g. to /tmp) by adding
MXE_TMP := /tmp
to the settings.mk file.
3. Build required MXE packages for the targets specified above with
cd /opt/mxe
make qttools qtwinextras sdl2 ogg vorbis lame a52dec faad2 fdk-aac libmad opus fribidi libass xvidcore x264 x265
This pulls in all the dependencies and can take a couple of hours. The final
total size of the /opt/mxe folder may be about 2.2G. Please note that twolame
is not available as a shared library and x265 has not been packaged for MXE as
of this writing.
4. To enable hardware-accelerated encoding provided by NVIDIA graphics cards of
the Kepler generation and later, download the file "nvEncodeAPI.h" e.g. from
https://raw.githubusercontent.com/FFmpeg/FFmpeg/master/compat/nvenc/nvEncodeAPI.h
and copy it to /opt/mxe/usr/i686-w64-mingw32.shared/include/ or
/opt/mxe/usr/x86_64-w64-mingw32.shared/include/ correspondingly.
5. Create a user-writable directory 'out' in '/opt/mxe/usr/x86_64-w64-mingw32.shared'
and in '/opt/mxe/usr/i686-w64-mingw32.shared' respectively.
6. Enter the Avidemux top source directory and run
bash bootStrapCrossMingwQt5_mxe.sh
to cross-compile a 32 bit Avidemux version or
bash bootStrapCrossMingwQt5_mxe.sh --64
to cross-compile a 64 bit version. Run
bash bootStrapCrossMingwQt5_mxe.sh -h
to see the list of all available options. It is assumed that 'zip' utility is
installed and in $PATH. Copy the 'avidemux_rYYMMDD-hhmmss_win{32,64}Qt5.zip'
file from the 'packaged_mingw_build_YYMMDD-hhmmss' directory to a Windows
partition, extract it on Windows and run 'avidemux.exe' from there.
7. Issues:
As of this writing, twolame, aften, vapoursynth and avsproxy are not available.
