<pre wrap="">It's been a while since I last posted here but I've kept a watch on
MythTV development and have seen lots of improvements.
Recently I acquired a few Raspberry Pi2's for a project and thought it
might be challenging to get one working with Myth using the integrated
video hardware. I've noticed a few other users talking about this too.
I've had a Raspberry Pi2 running MythTV 0.27 frontend for about 6 weeks
now and it feels fairly robust. It uses the OpenMAX APIs to render
video using the VideoCore hardware with hardware de-interlacing. It
also includes an optional OpenMAX MPEG decoder (£2 license required)
that provides hardware decoding. The OSD can either be softblend or EGL
based OpenGL2. It also supports visualisation, PiP and PbP. Audio is
best served via ALSA and there are 2 patches to make ALSA work nicely on
a RPi2
The patches (32 in total) also include an OpenGLES2 based video renderer
and OpenGL GUI although the GUI (based on Qt 5.4) is still a little
flaky - the Qt GUI is much more stable.
If anyone would like to try it and provide some feedback then checkout
the fixes-0.27-rpi2 branch from here:
<a class="moz-txt-link-freetext" href="http://www.softsystem.co.uk/git/mythtv.git">http://www.softsystem.co.uk/git/mythtv.git</a>
The server is running on a RPi2 too so give it some time :-)
Cross build and runtime instructions for a Debian based host are here:

A pre-built archive (93MB) is available here:
<a class="moz-txt-link-freetext" href="http://www.softsystem.co.uk/download/mythtv/mythtv-v0.27.5-74-g921a92e-RPI2.tar.bz2">http://www.softsystem.co.uk/download/mythtv/mythtv-v0.27.5-74-g921a92e-RPI2.tar.bz2</a>
To try this, after downloading on the RPi, follow the runtime
instructions in mythtv_for_rpi.txt (above).
If there's a demand I could port the changes to current master too.
Comments and suggestions please.

Great work!<br>
<br>
<big><big><tt>I setup 0.27 fixes backend with DVB-T tuner and
have noticed the following (openmax is setup, gpu_mem 256,
using eglfs):</tt><tt><br>
</tt><tt><br>
</tt><tt>1. Immediate seg fault when accessing Programme
Guide within Live TV, Programme Guide displays ok outside
of Live TV, then need to reboot the pi2 as it no longer
responds to keyboard input.</tt><tt><br>
</tt><tt><br>
</tt><tt>2. Attempting to set a Recording from Programme
Guide always fails:</tt><tt><br>
</tt><tt> Driver error was [2/1048]:</tt><tt><br>
</tt><tt> QMYSQL3: Unable to execute statement</tt><tt><br>
</tt><tt> Database error was:</tt><tt><br>
</tt><tt> Column 'next_record' cannot be null</tt><tt><br>
</tt><tt><br>
</tt><tt> I note the backend is using qt4 (Ubuntu ppa
0.27/fixes install) is this a qt4/5 issue ?<br>
<br>
3. Possible gpu memory leak when live TV playing and
Playback data on-screen (keyboard "m" > Playback >
Playback Data). bcmstat utility
(<a class="moz-txt-link-freetext" href="https://github.com/MilhouseVH/bcmstat">https://github.com/MilhouseVH/bcmstat</a>) shows GPU free
memory slowly reducing when run with the "g" option from
ssh console.<br>
<br>
<br>
I have a mythtv 0.28 test system available (with DVB-S/S2
tuners) and would be happy to help with any testing.<br>
<br>
I tried building from source, but am having trouble with
qtwebkit not building - any tips ?<br>
