libgles2-mesa-dev breaks gstreamer-imx video acceleration (14.04 armhf)

[J.]

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.

that doesn't sound right, a -dev package can't break it, sounds like you were missing some updates or getting a mixed set of them

anyway, it's been four years, probably not an issue anymore if it ever was
