Updated main code to SVN #20555

Lots of new features/improvement in this release... It has been tested quite intensively so I hope it will not introduce much problems.

New:

1. *Easier sound setup for HDMI connection
   

2. *AC3 upmixer. It is disabled by default. See below on how to configure it
   

3. *VDPAU patch 20549
   

4. *New browse all tuners patch (backport of changeset 19483)
   

5. *New software volume mixer, change volume even with digital audio (see below)
   

AC3 Upmixer

Based on ticket #5900.

Sound can now be upmixed to 5.1 AC3. By default the AC3 upmixer is disabled, you need to go into Setup -> General -> Audio and check AC3 upmixer.

Note: Passthrough works slightly differently than before. With AC3 upmixer enabled, if in the audio settings, you set Max Audio Channels to “Stereo”, you will only ever get stereo sound, even with AC3 and DTS passthrough enabled. If that’s not what you want, set Max Audio Channels to 5.1.

You can temporarily disabled the upmix while playing a video be pressing Ctrl + U or going into the Menu and selecting “Toggle Upmix”

Software volume control

Based on ticket #6279.

You can now control the audio volume even for AC3 and DTS stream. To do so go in Setup -> General -> Audio and check “Use internal volume controls”. For the mixer device select “software”.

Once set, if you change the volume using [ or ] , it will work even with AC3 and DTS.

HDPVR preliminary support.

HDPVR support has been added, but if you want to activate it you will have to compile the package yourself. I do not have a HDPVR myself, so I can’t say if it works.

Activate the source repository, do:

apt-get source mythtv

go into the folder mythtv-testing, edit debian/patches/00list

and uncomment the line:

#46_hdpvrsupport

To compile:

First install all the required dependencies

$ sudo apt-get build-dep mythtv

$ cd mythtv-testing

$ dpatch apply-all

#If on Intrepid or Hardy, do:

$ dpatch deapply 30_python26_transition

#Now compile

$ CFLAGS="-g -O2 -fPIC -DPIC" ./configure --compile-type=debug --prefix=/usr --runtime-prefix=/usr --enable-lirc --enable-audio-alsa --enable-audio-oss --enable-audio-jack --enable-dvb --enable-ivtv --enable-firewire --enable-joystick-menu --enable-opengl-vsync --with-bindings=perl --enable-opengl-video --enable-ffmpeg-pthreads --enable-vdpau  --enable-xvmc --enable-xvmc-vld --enable-xvmc-pro --enable-glx-procaddrarb --enable-libfaad --enable-libfaac --enable-libmp3lame --enable-libxvid --enable-libfftw3 --enable-hdpvr

$ make

$ make install

Before you run it, make sure you read:

http://mythtv.org/wiki/Patch_myth.21-fixes_for_hdpvr_on_Ubuntu_8.10

Obviously ignore how to download, patch and compile mythtv as I’ve done it for you.

You need to modify your database schema. This will break future automatic update.

You’ve been warned!
