Download mlbviewer:
Go and grab the latest version from the sourceforge page below:
http://sourceforge.net/projects/mlbviewer/
Unrar:
tar -zxvf mlbviewer2012.tar.gz
It doesn’t require any installation but you will need a few extras and the easiest way to install them is shown below:
Download PyXML:
PyXML is an XML processing tool for python which this project uses, sometimes it can be tricky to install python modules so we’ll be using setuptools which you can get from the link below.
If you’re unsure of what version you need, open terminal and type “python”, this will show the version of python you’re running. Mine was 2.7.4 so I downloaded “setuptools-0.6c11-py2.7.egg” I would imagine yours would be similar.
http://pypi.python.org/pypi/setuptools#cygwin-mac-os-x-linux-other
Once you have it, run it (replacing the version you downloaded for the one here):
sudo sh setuptools-0.6c11-py2.7.egg
Now to install PyXML it’s as simple as running:
sudo easy_install pyxml
That’s it, you’re done.
Optional – Install MPLAYER2:
MPLAYER2 offers at lot of advantages over MPLAYER however we’re most interested in it because it offers better streaming support and handle stream rate switches (important if you enable adaptive streaming in nexdef mode).
sudo add-apt-repository ppa:motumedia/mplayer-daily
sudo apt-get update
sudo apt-get install mplayer2
(Thanks to – Web Upd8)
Optional – Install mlbhls (for nextdef | HD):
Instructions as per in REQUIREMENTS-2012.txt in the mlbviewer package.
You’ll also need some extra packages which aren’t stated:
sudo apt-get install libconfig-dev libcurl4-gnutls-dev
svn co https://mlbtv-hls-nexdef.googlecode.com/svn/branches/experimental mlbhls
cd mlbhls
make
sudo cp mlbhls /usr/bin
Once that’s done, you should be able to get the higher bitrate streams too!
Using mlbplayer:
Setup:
The first time you run mlbviewer it will generate a config file which you’ll need to enter your Premium MLB.TV account details in, running mlbviewer will tell you where this file is located:
python mlbviewer.py
Go edit the file and enter your email as the “user” and your password after “pass”.
Now re-run mlbviewer and it should start up!
python mlbviewer.py
Sit back and enjoy!
fatal error: curl/curl.h: No such file or directory
If you’re missing the curl/curl.h header file, chances are you’re just missing the correct dev package file for the curl library.
sudo apt-get install libcurl4-gnutls-dev
That should fix it.
If you’re trying out the latest version of Ubuntu, 12.04 or Precise Pangolin and you want to keep your old /home partition, chances are you’ve come across the installation hanging on a process “Removing conflicting operating system files…”. No worries, this seems to be a common bug and there’s a pretty easy work around.
Continue with the installation, without asking for the /home partition to be mounted. Only set the root partition (/) and your swap space.
Once the installation is complete, reboot and load it up.
Now, you’ll want to find the partition that /home is mounted under, this will likely be /dev/sdxN, where x is the drive letter and N is the partition number (i.e mine is located under /dev/sda5).
If you’re unsure, you can list the possible drives using the following command:
ls /dev/ | grep sd
And then you can mount each drive under in a temp directory and check what’s in there:
mkdir temp
mount /dev/sda1 temp
Once you know which partition you want, it’s time to edit your /etc/fstab/
sudo gedit /etc/fstab
For those who don’t go digging around in the config files of linux, this may look pretty daunting, but it isn’t. All you really need to do is add a new line to mount your home partition. Here’s mine:
/dev/sda5 /home/ ext4 defaults 1 2
The first part is the partition that’s being used, next what the partition is. Next is the file system type. Followed by default options and then the dump and pass values.
Once you’ve saved this file with the appended line, reboot your system. Now you should find your old home partition is mounted normally and you can get on with your install.
Those pesky windows buttons (maximise, minimise and close) default to the left of the menu bar after a new Ubuntu installations, and it’s been happening since 10.04. Most people, like myself, are stuck in our ways and just want them back where they belong. It’s pretty easy to do this, just open up a terminal (ctrl+alt+t) and copy in the following:
gconftool -s /apps/met>gconftool -s /apps/met>gconftool -s /apps/metacity/general/button_layout -t string menu:minimize,maximize,close
Once you hit enter, you should see the buttons return to their rightful place on the right, also in the right order.
Install Jupiter
Instructions for Ubuntu 11.10, 11.04, 10.10, 10.04: http://www.webupd8.org/2011/09/jupiter-applet-finally-available-for.html
sudo add-apt-repository ppa:webupd8team/jupiter
sudo apt-get update
sudo apt-get install jupiter
Jupiter comes with a useful script to disable and re-enable the touchpad/track pad, it can be ran using the following command:
sudo /usr/lib/jupiter/scripts/touchpad
Now all you’ll need to do is add this command to a keyboard shortcut, below are instructions for several desktop environments.
In xfce:
Applications > Settings > Settings Manager
Click Keyboard
Click on the “Applications Shortcuts” tab.
Click Add:
Here you will be promped with a new window asking for the command you wish to run, enter the following:
sudo /usr/lib/jupiter/scripts/touchpad
Click OK and it will now ask for a keyboard shortcut. Simply press the key combination you want to assign to disabling the touchpad (for example, I used Alt+F1) the keys you’re pressing will show up and the window will close.
You’ll now see the command and shortcut in the list and you can now press that key combo to disable the trackpad and press it again to re-enable it.
In Gnome:
In Unity:
bish bash bosh.
./blender
connect failed: No such file or directory
ndof: spacenavd not found
AL lib: pulseaudio.c:331: PulseAudio returned minreq > tlength/2; expect break up
Floating point exception
Download and install the associated package to your processor from here : https://launchpad.net/ubuntu/oneiric/+package/python-openal
Restart your computer and the issue should now be resolved.
Download the latest from here:
http://kernel.ubuntu.com/~kernel-ppa/mainline/
The folders correspond to kernel versions and should also include the ubuntu version, for example I chose to update 11.10 (oneiric) from “3.0.0-14-generic” to “3.1.4″, this was in a directory called “v3.1.4-oneiric/“.
You’ll need 3 files (replace * with the kernel version you’ve downloaded):
linux-headers-*_all.deb
For 64 bit systems (replace * with the kernel version you’ve downloaded):
linux-headers-*_amd64.deb
linux-image-*_amd64.deb
For 32 bit systems (replace * with the kernel version you’ve downloaded):
linux-headers-*_i386.deb
linux-image-*_i386.deb
Once you have the files, install them in the following order using these commands (of course, replacing the version number for the ones you’ve downloaded):
sudo dpkg -U linux-headers-3.1.4-030104_3.1.4-030104.201111281851_all.deb
sudo dpkg -U linux-headers-3.1.4-030104-generic_3.1.4-030104.201111281851_amd64.deb
sudo dpkg -U linux-image-3.1.4-030104-generic_3.1.4-030104.201111281851_amd64.deb
Once that’s done, reboot. Once you’re back use the following command to check that the kernel you’re using is the one you’ve just downloaded and installed!
uname -r
It’s been a while since I bothered, the reason being it’s always seemed like an un-worthwhile struggle to get it working but either things changed or I was doing something to overcomplicate the process but it’s actually pretty simple to get surround sound up and running on your Linux machine. Now, I’m not going to go in to how to install the drivers for your specific sound card, because there are so many and I don’t have them all and most times on most popular distributions (Debian, Ubuntu, Mint, Fedora, OpenSuse etc) you’re going to notice that the sound card is actually already supported. What I will be doing is showing you how easy it was to get my 5.1′s set up (and the same will be said for 7.1′s).
Step 1:
First off you’re going to want to edit the pulseaudio configuration file to add the number of speakers you’re using, it’s default is set to 2.
sudo gedit /etc/pulse/daemon.conf
Near the bottom of the file, there will be a line which looks like this:
;default-sample-channels = 2
The semi-colon is a comment, so this line isn’t actually doing anything unless you remove that. I would suggest leaving that line alone and adding a new line at the bottom:
default-sample-channels = 6
If you’re using 5.1′s the number of channels will be 6, 7.1′s will be 8 and I think you get where I’m going with this? So in this example, I’m using 5.1′s.
Now save and close that file. You’ll need to reboot your system now too, so that these changes will take effect.
Step 2:
So you’re back? Good..
Now you’re going to want to open up the Sound Preferences, usually you can do this by clicking on the little sound icon in your panel, or System > Preference > Sounds from the menu.
From here, you’ll want to click on the Hardware tab. Near the bottom it’ll say Profile: with a drop down box next to it. Here you can select the type of set up you have, as you can see in the screenshot I have an “Analogue Surround 5.1 Output”, yours might be different and that’s cool and if you don’t know feel free to try a few out. Next to that drop down box is a button which says “Test Speakers”, this didn’t work for me so I have to use an online test but give it a try as it might work!
That’s it, you should be done!
During installing the OpenNi kinect drivers, found here: https://github.com/OpenNI/OpenNI, I came across this error:
make[1]: Entering directory `/home/alex/kinect/OpenNI/Platform/Linux-x86/Build/Samples/SimpleViewer.net’
gmcs -out:../../../Bin/Release/SimpleViewer.net.exe -target:winexe -unsafe -o+ -r:OpenNI.net.dll -r:System.Windows.Forms.dll -r:System.Drawing.dll -lib:../../../Bin/Release ../../../../../Samples/SimpleViewer.net/*.cs ../../Res/AssemblyInfo-OpenNI.cs
error CS0006: cannot find metadata file `System.Windows.Forms.dll’
Compilation failed: 1 error(s), 0 warnings

make[1]: Leaving directory `/home/alex/kinect/OpenNI/Platform/Linux-x86/Build/Samples/SimpleViewer.net’
make: *** [Samples/SimpleViewer.net] Error 2
To fix it, simply install the following package:
sudo apt-get install mono-complete
Once finished, re-make and make install and everything should be dandy!
If you’re getting a similar error to this while trying to compile java files (.jar) then you’re probably missing the jdk, in ubuntu it’s called “sun-java6-jdk” so just go ahead and install that and all should be good!
make[1]: Entering directory `/home/alex/kinect/OpenNI/Platform/Linux-x86/Build/Wrappers/OpenNI.java’
javac -d Release ../../../../../Wrappers/OpenNI.java/src/org/OpenNI/*.java
/bin/sh: javac: not found

make[1]: Leaving directory `/home/alex/kinect/OpenNI/Platform/Linux-x86/Build/Wrappers/OpenNI.java’
make: *** [Wrappers/OpenNI.java] Error 2
FIX:
sudo apt-get install sun-java6-jdk
