I created this Dockerfile to build latest git version of gstreamer and plugins for my raspberry pi. In this case I am not using a real cross-compiler. I just run the entyre build inside qemu-static-arm that runs in a raspbian chroot. This is way faster than full system emulation yet slower than real cross-compilation. It took 1 - 2 hrs on my macbook pro.
If you just want to download prebuilt binaries skip to Installing
docker build -t raspbian-chroot .
docker run --rm -it -v $(pwd)/build:/sysroot/build:delegated raspbian-chroot
This will open a bash terminal. This bash terminal lives inside the emulated raspberry chroot like this
docker container -> chroot raspberry filesystem -> qemu-arm-static -> bash
build is mounted to /sysroot/build which you see as /build in the chrooted fs.
So you can do
cd build
bash build.sh
# whatever
The build.sh script generates a new version of build/usr_local.tar.
In order to install the prebuilt gstreamer you can transfer and decompress build/usr_local.tar to your raspberry and then
scp build/usr_local.tar pi@raspberrypi.local:~
ssh pi@raspberrypi.local
sudo apt-get remove gstreamer-1.0 # remove raspbian version of gstreamer
cd /
tar -xvf /home/pi/usr_local.tar
export LD_LIBRARY_PATH=/usr/local/lib
gst-inspect-1.0 --version # enjoy
