Shorten is an old format to create lossless compressed audio files. FLAC is the new way. I’ll show some of the joy I’ve had trying to convert the old shn files to flac.

ffmpeg seems to want to do it if you have it compiled with the correct libraries.
ffmpeg -i file.shn file.shn.flac

A java signaling server for connecting up the various clients.

Authentication will be done via major providers, users can pick their favorite- facebook, google, twitter, microsoft, linkedin. This will allow us to use their profile picture, email address, and if they are greater that 18 from the provider.

Websockets is used for the signaling to/from the server.

Webrtc will be used for the audio/video and data streams. Data streams will be used to test the users bandwidth (even though getStats is broken for data streams so we’ll write our own).

From the start we will accommodate just two channels- 24×7 reruns and live. Each channel will serve two streams: standard and low quality (for users with limited bandwidth or data caps imposed by their ISP). Standard quality will be around 1.5 to 3 Mbps and low quality will be 500 Kbps.

Tier zero is the original stream. Tier 1 is hosted at My Delaware TV and will serve several tier 2 users. Tier 2 users will serve tier 3 users, and so on down the pyramid. Testing will provide the practical number of users each tier can serve, all the way down to tier n.

Say tier 1 will serve 4 tier 2 users. Tier 2 will each serve two tier 3 users, allowing us to accommodate 4+4*2= 12 total users. Tier 10 will be able to accommodate 2044 users.

3 12
4 28
5 60
6 124
7 252
8 508
9 1020
10 2044

To directly serve that many users a 2 Mbps feed My Delaware TV would need 4088 Mpbs. At Verizon business FIOS pricing using my current bill/speed, I would need 28 150 Mbps lines at a cost of $4,140/month.

Been running mythtv for years. A newer setting is the security pin on the mythtv-setup – general page. It appeared as blank and needed to be 0000.

Schedules Direct must have (well worth the money)

mythtv guide not showing anything A bit of a pain, but it really was necessary to manually edit every channel.

Update 2018-10-31
Before I started any updates, I noticed Chip Porter uses HD Home Run. I decided to check it out, but the reviews were just awful. They say “setting up a DVR on a PC is difficult, we make it easy”. I guess they learned just how difficult it is.

I need to update mythtv to support the latest python, but that meant I needed a new QT.
First I installed from QT: https://www.qt.io/. That put it in /opt/Qt5.11.2/.
Then I created
installed it, created ~/.config/qtchooser and put this in there:
/opt/Qt5.11.2/bin
/opt/Qt5.11.2/lib

and checked it with
qmake -v
QMake version 3.0
Using Qt version 5.5.1 in /usr/lib/x86_64-linux-gnu

I also finally found a PPT but didn’t use it.
sudo add-apt-repository ppa:beineri/opt-qt-5.11.1-xenial

I went to my mythtv src directory, did a ‘git pull’ and
./configure \
–enable-proc-opt \
–enable-libmp3lame \
–enable-libx264 \
–enable-libvpx \
–enable-libxvid \
–enable-sdl \
–with-bindings=perl,php \
–perl-config-opts=”INSTALLDIRS=vendor” \
–disable-mythlogserver \
–enable-nonfree

make -j 5
still failed with
mythversion.h:9:2: error: #error You need Qt version >= 5.2.0 to compile MythTV.
#error You need Qt version >= 5.2.0 to compile MythTV.

I ended up using ansible https://github.com/MythTV/ansible
First, install the package, then git the source, then run
ansible-playbook -i hosts qt5.yml

That seemed to do it, install worked and kodi looks ok.

Mythweb is always screwed so we’ll dig into that now.
