Peter,
Slightly OT, but it might have a bearing on some of the audio/video
issues various people have been reporting.
I am running mythtv-backend 0.28, so I decided to do a build of your
master branch on a Pi2 (setup with rootfs on hard disk) using Qt5.3.2 on
Jessie, including plugins (News and Web work fine).
Whilst doing 'lsof -p <pid mythfrontend>' I noticed a double linkage to
libEGL.so and libGLESv2.so:
mythfront 16958 pi mem REG 8,1 146848 11669836
/usr/lib/arm-linux-gnueabihf/libEGL.so.1.0.0
mythfront 16958 pi mem REG 8,1 201752 24129012
/opt/vc/lib/libEGL.so
mythfront 16958 pi mem REG 8,1 105768 24129014
/opt/vc/lib/libGLESv2.so
mythfront 16958 pi mem REG 8,1 29996 11669840
/usr/lib/arm-linux-gnueabihf/libGLESv2.so.2.0.0
I believe the correct ones are in /opt/vc/lib.
I had also done a build using Qt5.5.1 (full build of Qt5.5.1 on Pi2 took
a while!), but one of the instructions was to fixup some links in Jessie
(see https://wiki.qt.io/Native_Build_of_Qt_5.4.1_on_a_Raspberry_Pi the
installation protocol part for Full native build of Qt 5.5.1 )
### fix the egl/gles library nonsense

sudo mv /usr/lib/arm-linux-gnueabihf/libEGL.so.1.0.0
/usr/lib/arm-linux-gnueabihf/libEGL.so.1.0.0.backup
sudo mv /usr/lib/arm-linux-gnueabihf/libGLESv2.so.2.0.0
/usr/lib/arm-linux-gnueabihf/libGLESv2.so.2.0.0.backup
sudo ln -s /opt/vc/lib/libEGL.so
/usr/lib/arm-linux-gnueabihf/libEGL.so.1.0.0
sudo ln -s /opt/vc/lib/libGLESv2.so
/usr/lib/arm-linux-gnueabihf/libGLESv2.so.2.0.0
The other things I had to to do for my setup in /boot/config.txt
uncomment "disable_overscan=1" tv is LG 42LM3450
set "hdmi_group=1"
set "hdmi_mode=31"
The hdmi settings give me 1080p 50Hz (for UK), otherwise Pi2 defaulted
to 1080p 60Hz
