Me

My Life

Electric Power Engineer living in Boston, MA

I can be reached for mythtv purposes at adeffs_dot_mythtv_at_gmail_dot_com.

My Myth Contributions

I don't really code, but I try to be active in bug and feature testing.

TVRage.com

This project has been moved to Google Code to make managing it easier.

TVRage.com import perl script for adding archived shows to the MythTV Watch Recordings DB or the MythVideo? database (pre-0.22).

6200changer.sh

I wrote a script for handling my DCT-6200 cable boxes connected via firewire that changes the channel and uses firewire_tester to stabilize the connection before Myth tries to record. This has, over the last two years, allowed me to not fail in recording a single show.

To use, set it up in mythtv-setup as the channel change script. Give it the GUID of the box as shown in mythtv-setup. The script takes two variables, the first being the GUID (which is why you have to specify it) and the second is the channel number (which mythtv automatically feeds it at the end of the command you give it). The script then changes the channel on that GUID and runs firewire_tester. In running firewire_tester it requires that it show the connection is stable twice. If it iterates 10 times it will automatically re-tune the channel, and after 50 attempts total it will send Myth the "failed" result, otherwise it will send Myth the "success" result.

You can change the script to use another channel changer if you require.

#!/bin/bash
#

GUID=`echo "$1"|sed -r "s/[A-Z]+/\L&/g"`
CHANNEL=$2

NODE=`plugreport | grep $GUID | awk '{if (($1 == "Node")  && ($4 == "'"0x$GUID"'
")) print $2}'`
echo "Node: '$NODE'"
echo "Changing to channel $CHANNEL"
6200ch -v -s -g $GUID $CHANNEL
#maybe a pause is needed?
sleep 4

STABILIZE="1"
COUNT=0
TOTALCOUNT=0
STABLECOUNT=0
echo "Stabilizing Firewire Connection!..."
#maybe an initial run followed by a verification run?

#initial run
firewire_tester -B -r2 -n$NODE

#while [ "$STABILIZE" != "Broadcast Fix: Success (already stable)" ]
while [ $STABLECOUNT -lt 2 ]
do
       STABILIZE=`firewire_tester -B -n$NODE|grep "already stable"`
       if [[ "$STABILIZE" != "Broadcast Fix: Success (already stable)" ]]
       then
               echo "Not Stable! Attempt $COUNT"
               ((COUNT+=1))
               ((TOTALCOUNT+=1))
               if [ $TOTALCOUNT -gt 50 ]
               then
                       echo "FAILED to Stabilize!!"
                       exit 1
               fi
               if [ $COUNT -gt 10 ]
               then
                       6200ch -v -s -g $GUID $CHANNEL
                       COUNT=0
                       firewire_tester -B -r2 -n$NODE
               fi

For those of us that want to run mythfrontend without a window manager, here is the information the dev's don't want you to see:

disable window manager

From, http://ubuntuforums.org/showthread.php?p=10798400#post10798400

assuming lightdm is being used,

echo "manual" | sudo tee -a /etc/init/lightdm.override

The splash screen can cause some problems, so I would suggest you to disable it. Edit the /etc/default/grub file and replace the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" with GRUB_CMDLINE_LINUX_DEFAULT="quiet". Then generate a new Grub2 config file,

sudo update-grub


.xinitrc

When X starts it looks to the users home directory for the .xinitrc file. There are two options at this point for how to use .xinitrc, one will load a window manager, the other will not.

No Window Manager

For no windowmanager, create/edit the user's .xinitrc and add,


Script.png .xinitrc

xset -dpms s off
xsetroot -solid black
mythfrontend -l /home/mythtv/mythfrontend.log
#mythtv-setup
#xterm

This will turn off dpms, turn the X default background color black and log to /home/mythtv/mythfrontend.log. These options can, obviously, all be changed.

Also included is an easy way to access mythtv-setup or xterm, just uncomment the appropriate line and comment out the mythfrontend line.

Note that running mythfrontend without a window manager is not a supported configuration. You may run into focus problems when trying to press buttons, enter text and generally use the system. These issues have mostly been fixed in the newer versions of MythTV and many users run this method successfully, especially with Mythbuntu

Encoding

I've become somewhat of a mencoder/BASH scripting guru through my many adventures using it and writing scripts.

HR.HDTV script

I wrote this script to create my own versions of what "the scene" calls HR.HDTV encodes. These look decent on HDTV's up to about 50". Beyond that I highly recommend using x264 at 720p encodes. It may take a lot more processing to get done, but if your TV is that big you'll thank me for recommending it.

So what this script does is convert any 1080i or 720p recording to "HR.HDTV" which is basically a 960x544 resolution file with the original AC3 soundtrack. It will encode to the CD size standard of putting one hour of tv on a CD (ie 44minutes into 700MB, 22minutes into 350MB). It's also a good start to doing other conversions as the options can easily be changes to do things like encode to x264 at 1280x720(hint hint)...

You will need PerlCalc for some math in the script...

# 2. Calculate final file size (350MB or 700MB)
# 3. Calculate final video size based on final file
#    size and audio size.
# 4. Encode.

NeroAAC in linux

NOTE: Nero recently released a version of their encoder that is linux native, but I haven't updated my script for it since I actually rarely use it now, I've been using dbPowerAmp at work...

Recently Nero released their wonderful AAC encoder for "DOS" (command line app in windows). Since I'm a huge fan of AAC for compressed audio due to its quality I was hoping they'd release a linux version, but as it turns out their windows version was designed to work a-o-k in linux under WINE!

The only caveats I've found is that you need to have the folder where you music ready for conversion is mapped as a drive in Wine. As well, the filenames cannot have any periods in them except for the one that designates the extension (ie this.song.is.good.flac is no good but this song is good.flac is fine), which is an issue I know how to solve with a simple perl rename, but have yet to tackle in the script... Other than that, your good to go.

So what I did, is I wrote a script that will convert any format mplayer supports, as well as APE to M4A. Right now I really only have it setup for WAV, FLAC and APE though, but its pretty easy to add other formats. For mplayer supported formats look at the FLAC functions, for formats that require another decoder to get to WAV look at the APE section. This script can also recursively enter folders, so you can rip a whole lot of CD's (using cdparanoia or EAC under WINE of course!) into seperate folders and run this script from their root and it will go into each folder and convert! how handy!

This site has some great info on the encoder, as well as how to encode directly to M4A when ripping with EAC. This is a good guide to do the same in K3B.

This script has two command line options as of now. First it will allow you to delete the original after a successful encode using -e, or you can specify a specific directory with -d.

This script also has some defined options near the top, EncoderDir=~/.wine/drive_c/Program\ Files/Nero QualityLevel="0.8"

EncoderDir is obviously where your neroAACenc.exe file is, and Quality level is a numerical value for the recording quality setting. I don't like compressed audio and find that 0.8 is a good balance for my ears and my desire to keep file sizes down. This equates to about 300Kbps, which is rather large for even the MP3 format, so feel free to change this value for your needs.

For those that used the old Nero encoder with "Quality Levels", here's a quick conversion chart...
