Public bug reported:
Installing libgles2-mesa-dev 10.1.3-0ubuntu0.6 armhf together with
libxcb-randr0 breaks accelerated video playback with gstreamer-imx on
UDOObuntu 2.1.2 (based on Ubuntu 14.04 LTS - see
http://www.udoo.org/downloads/).
This could be broken installation scripts or missing Pre-Depends.
For example, video playback works fine on udoobuntu-udoo-qdl-desktop_2.1.img:
# VIDEO + SOUND OK - without libgles2-mesa-dev installed
gst-launch-1.0 playbin uri=file:///home/udooer/big_buck_bunny_720p_h264.mp4
gst123 big_buck_bunny_720p_h264.mp4
Introduce breakage by installing libgles2-mesa-dev *without* having
libxcb-randr0 installed:
sudo apt-get -y --purge remove libxcb-randr0 && sudo apt-get -y install
libgles2-mesa-dev
gst-launch-1.0 playbin uri=file:///home/udooer/big_buck_bunny_720p_h264.mp4
# BLACK & PAUSED
gst123 big_buck_bunny_720p_h264.mp4 # SOUND ONLY + BLACK WINDOW
Note that just uninstalling libgles2-mesa-dev does *NOT* fix the issue,
only uninstalling libxcb-randr0 and reinstalling it before or without
libgles2-mesa-dev brings video playback back to live.
Workaround1, complete libxcb-randr0 installation before installing
libgles2-mesa-dev:
sudo apt-get -y --purge remove libxcb-randr0 && sudo apt-get -y install
libxcb-randr0 && sudo apt-get -y install libgles2-mesa-dev
# VIDEO + SOUND OK for gst-launch-1.0 and gst123
Workaround2, install all dependencies before libgles2-mesa-dev:
sudo apt-get -y --purge remove libxcb-randr0 && sudo apt-get -y install
libegl1-mesa-dev && sudo apt-get -y install libgles2-mesa-dev
# VIDEO + SOUND OK for gst-launch-1.0 and gst123
So it looks like the libgles2-mesa-dev installation process if run
before libxcb-randr0 has finished installation (libc triggers run, etc),
messes up some configuration bits of libxcb-randr0 which stick around
even after libgles2-mesa-dev is uninstalled.
