GStreamer development in embedded with sbox2

I’ve heard many people having problems cross-compiling GStreamer on ARM systems so I decided to write a step-by-step guide describing how I do it.

This guide is meant for scratchbox 2. You can read this old post where I explain how to install it. I’m using CodeSourcery 2009q3 but any compiler would do.

Base

I’m going to install everything to “/opt/gst” on the build system, however this should go in the same directory in the target system.

So, in order for the packages to find each other:
export PKG_CONFIG_PATH=/opt/gst/lib/pkgconfig

glib

git clone git://git.gnome.org/glib
cd glib
git checkout -b stable 2.22.3
./autogen.sh --noconfigure
sb2 ./configure --prefix=/opt/gst --disable-static --with-html-dir=/tmp/dump
sb2 make install

gstreamer

git clone git://anongit.freedesktop.org/gstreamer/gstreamer
cd gstreamer
git checkout -b stable RELEASE-0.10.25
./autogen.sh --noconfigure
sb2 ./configure --prefix=/opt/gst --disable-nls --disable-static --enable-binary-registry --disable-loadsave --with-html-dir=/tmp/dump
sb2 make install

That’s it! You have a GStreamer development environment

Embedded stuff

If you are an embedded developer, chances are you would like to build gst-openmax or gst-dsp, or perhaps your own plugin. So here’s how to do it.

gst-openmax

git clone git://anongit.freedesktop.org/gstreamer/gst-openmax
cd gst-openmax
git checkout -b stable v0.10.0.5
./autogen.sh --noconfigure
sb2 ./configure --prefix=/opt/gst
sb2 make install

gst-dsp

git clone git://github.com/felipec/gst-dsp.git
cd gst-dsp
git checkout -b stable v0.6.0
sb2 make

note: I forgot to add the install target, just copy the plugin

There. It’s easy to develop your own plugin this way, or contribute to the existing ones Note that as long as you are not using esoteric new API’s these binaries should work on any other GStreamer setups. I do this on my N900 for example, which has an older GStreamer, but I still test gst-dsp linked to a newer one.

Plugins

Perhaps you still don’t have GStreamer in your target environment so you want all the muxers, demuxers, and so on. So let’s build them.

Some plugins have dependencies; if you want them to be built, you would need to install them first.

liboil

gst-plugins-base needs liboil, so let’s start there.

git clone git://anongit.freedesktop.org/liboil
cd liboil
git checkout -b stable liboil-0.3.15
sb2 ./configure --prefix=/opt/gst --disable-static --with-html-dir=/tmp/dump
sb2 make install

gst-plugins-base

git clone git://anongit.freedesktop.org/gstreamer/gst-plugins-base
cd gst-plugins-base
git checkout -b stable RELEASE-0.10.25
./autogen.sh --noconfigure
sb2 ./configure --prefix=/opt/gst --disable-nls --disable-static --with-html-dir=/tmp/dump --disable-pango
sb2 make install

note: I’m disabling pango because a bug in the build system

gst-plugins-good

git clone git://anongit.freedesktop.org/gstreamer/gst-plugins-good
cd gst-plugins-good
git checkout -b stable RELEASE-0.10.17
./autogen.sh --noconfigure
sb2 ./configure --prefix=/opt/gst --disable-nls --disable-static --with-html-dir=/tmp/dump
sb2 make install

gst-plugins-ugly

git clone git://anongit.freedesktop.org/gstreamer/gst-plugins-ugly
cd gst-plugins-ugly
git checkout -b stable RELEASE-0.10.13
./autogen.sh --noconfigure
sb2 ./configure --prefix=/opt/gst --disable-nls --disable-static --with-html-dir=/tmp/dump
sb2 make install

Conclusion

Not that hard, was it? Just copy all the binaries to your target system on ‘/opt/gst’ and fire up some ‘gst-launch’ commands Oh, wait, you’ll need to add /opt/gst/bin to your PATH. Or use sb2 to compile your own plugin and run on any system.
