Streaming Other HD Video Sites on the Raspberry PI

For those that are interested, this will allow you to stream internet shows like The Daily Show on your Raspberry Pi in HD with no lag.

A week or so ago I posted a hack which allowed people to stream youtube videos in the browser here. Unfortunately, this same method didnt work out of the box for some other video sites. They would stream a couple seconds then just end (I found this to happen with the daily show).

I now have a fix for that and have a script called youtube-safe, which can stream (high-quality with no lag on a decent internet connection) any video site that works with youtube-dl.

If you already have the Youtube scripts in my PiAUISuite installed, you can just update, otherwise you have to go through the install script and select which parts you want (this one being under youtube).

Install Instructions

sudo apt-get install git-core
git clone git://github.com/StevenHickson/PiAUISuite.git
cd PiAUISuite/Install/
./InstallAUISuite.sh

**NOTE, this will ask you if you want to install a lot of different scripts because it is a SUITE. You only have to pick the ones you want to use. If you only want to use the youtube scripts, press n on any other question except for the dependencies and youtube.

Update Instructions

cd PiAUISuite
git pull
cd Install
sudo ./UpdateAUISuite.sh

Once that is done, you can watch the daily show in 1080p like so:
youtube-safe "http://www.thedailyshow.com/full-episodes/"

Even better, if you have voicecommand installed on your system, add the following line to the bottom of your config file for it to play the newest daily show with your voice:
~Daily Show==youtube-safe "http://www.thedailyshow.com/full-episodes/"

Ill work on making a browser plugin for this as well.

Mounting the home directory on a different drive on the Raspberry Pi

I found myself struggling with SD card corruption this week.
I think it was due to a combination of overclocking and an old SD card. Although I use svn or git with most of my code, occasionally I do a lot of work in a day and forget to add a file. After this last time, I decided to move my home directory to a partition on an external HDD just in case.

I will be posting some file recovery methods later in case you have also lost data.

Start by making sure your external drive is connected and open a terminal.

First of all you need to have root privileges to do all this (or use sudo privileges)

Make sure your drive is not mounted. To unmount it:

umount /mntpoint
If you already have your external drive partitioned, skip to Step 4.

Step 1: Partition External Drive

The fdisk command with the -l flag can list all of your drives and partitions. So start by running that:

fdisk -l

Pick the HDD you want to use (mine was /dev/sdb but Ill put sdx and you can fill in appropriately) and run fdisk again to see partition information

fdisk /dev/sdx

You should be in an interactive prompt. Type p to see the partitions. There should be none. If there arent any, skip to Step 3.

Step 2: Deleting or resizing

If you need the old partitions and want to shrink them, type q to exit the fdisk prompt, otherwise skip to Step 3.

If you are using the partitions and just want to resize them, then there are various commands to do that (also its a good idea to have a back up).

For ext3/ext4, just use: resize2fs /dev/sdx #size

Or use parted

parted /dev/sdx (opens interactive prompt)

resize #size

For ntfs:

ntfsresize --size #sizeM /dev/sdx

Then open back up the fdisk prompt, you need to make new partitions that match.

Step 3: Writing partition changes

(Open fdisk back open if you closed it)

Now just use d #partition to delete any old partitions.

Then type n to make a new partition followed by p to make it a primary partition. If this is the only partition you need, you can make it the whole disk size. If you shrank a partition, you need to make two new partitions, with the first one having a size that matches your resize options.

Now type w to write changes to disk then q to quit. It will probably give you some warnings, it almost always does. Pay attention to them but dont freak out.

Now format the new partition (If you only made one partition #=1):

mkfs.ext4 /dev/sdx#

Step 4: Copying over your home directory files

Mount your new partition:

sudo mkdir /media/tmp

sudo mount -t ext4 /media/tmp

Navigate to your root folder

cd /home

Copy all your data recursively (this option seems to have worked the best for me to get all of the files including .bashrc and .vimrc files)

sudo cp -rp ./ /media/tmp

Step 5: Mounting your new home directory

Once that is finished, you can move the home directory and mount the new one (make sure no program is currently using the home directory or you will get errors).

sudo umount /media/tmp

sudo rm -rf /media/tmp (get rid of the tmp folder)

sudo mv /home /old_home

sudo mkdir /home

sudo echo "/dev/sdx# /home ext4 defaults,noatime,nodiratime 0 0" >> /etc/fstab

Again replacing x# with your drive number (mine was b2).

Now we can test it by mounting home. If this doesnt work, somewhere you messed up

sudo mount /home

After you have confirmed everything is working and copied over and you dont need your old home directory, you can delete it.

sudo rm -fr /old_home

Now you dont need to worry about SD Corruption.
