Bug ID: 759131
Summary: glimagesink compiled for GLES/EGL/dispmanx (without X)
fails on RaspberryPi
Classification: Platform
Product: GStreamer
Version: git master
OS: Linux
Status: NEW
Severity: normal
Priority: Normal
Component: gst-plugins-bad
Assignee: gstreamer-***@lists.freedesktop.org
Reporter: ***@ubicast.eu
QA Contact: gstreamer-***@lists.freedesktop.org
GNOME version: ---

I compiled gst-plugins-bad from git using 1.6 branch using the following
options

./autogen.sh CFLAGS="-I/opt/vc/include -I
/opt/vc/include/interface/vcos/pthreads -I
/opt/vc/include/interface/vmcs_host/linux/" LDFLAGS="-L/opt/vc/lib"
--disable-gtk-doc --disable-opengl --enable-gles2 --enable-egl --disable-glx
--disable-x11 --disable-wayland --enable-dispmanx

My environment is (Arch ARM):
* gst-plugins-base-libs 1.6.1-1
* gst-plugins-good 1.6.1-2
* gstreamer 1.6.1-1
* linux-firmware 20150904.6ebf5d5-1
* raspberrypi-firmware 20151130-1
* raspberrypi-firmware-bootloader 20151130-1
* raspberrypi-firmware-bootloader-x 20151130-1
* raspberrypi-firmware-examples 20151130-1
* raspberrypi-firmware-tools 20151130-1

Running Linux 4.1.13-1-ARCH

When starting a test pipeline, i get a critical error: "glGetString not defined
or returned invalid value"
