VLC Streaming

Sun, 03 Apr 2016 18:44:00 +0000

Here is my setup to use VLC running on a laptop with a webcam as a simple CCTV system that can stream to your mobile.

VLC was installed on a laptop running Ubuntu 14.4. The webcam input stream was found at

v4l2:///dev/video0

and the audio input was found at

alsa://hw:0,0

using the command line for VLC I started capturing these two devices, transcoding and streaming to http with the following script

For some reason .asf was the only encapsulation that worked, the filename you set pics the encapsulation. You can do all of this via the VLC gui, but you will need to change the string on the last page if you want a username and pass as VLC does not set that by default, instead sets the dst only.
Create the necessary port forward in the router if you wish to access via WAN, or leave locked down if using local only.

On the receiving device open VLC and open ‘Network Stream’ as http://[username]:[password]@[wanip or localhost]:[port]/[file]. E.g. http://jsmith:mypass@1.2.3.4:8080/go.asf

A bit more long winded but can also can be done via the VLC GUI :

TLDP - The Linux Documentation Project

Thu, 07 Mar 2013 23:01:00 +0000

As the name suggests this is a fantastic resource for Linux info, guides and howto’s. http://www.tldp.org/

The ‘Single File HTML’ is probably the simplest & fastest format for a kindle reader (as delivered by email to the device), with the one exception that the images wont load, but there are not many of these in the books.

Download Video from the BBC iPlayer

Sun, 22 Apr 2012 09:24:00 +0000

There is no quick answer to this from Google for Windows, but in Ubuntu it’s dead easy

$ sudo apt-get install get-iplayer

With the package is installed run

$ get-iplayer –get –url=

Get all the info and documentation here

Grub customiser / Ubuntu

Sun, 08 May 2011 11:05:00 +0000

Beats trying to find the right file to edit..

sudo add-apt-repository ppa:danielrichter2007/grub-customizer sudo apt-get update sudo apt-get install grub-customizer

Dead easy to use also

NTFS partitions and ntfs-config

Sat, 01 Aug 2009 18:51:00 +0000

Using windows partitions in Ubuntu is no problem, however if you need to rely on a stable mount point you will want to add ntfs-config.


$ sudo apt-get install ntft-config && sudo ntfs-config

If while playing around with this you lose the partitions and then can’t see them listed any more in the “New Partirions Found” popup when you load ntfs-tools you will need to clean your /etc/fstab file.


$ sudo gedit /etc/fstab

Be careful to only remove the windows mounts, these will have “ntfs-3g” written in the line.

Mounting ISO images and creating shell scrips

Mon, 04 May 2009 14:12:00 +0000

Problem: Mount an ISO image file

Good old terminal

To make a mount point “iso” and mount the CD image “image.iso”

$ sudo mkdir /media/iso && sudo mount -o loop image.iso

To unmount the ISO and clean up the /media directory

$ sudo umount /media/iso && sudo rmdir /media/iso

Always good to know the terminal commands, thanks nixCraft.

Add a script to nautilus

$ cd ~/.gnome2/nautilus-scripts && sudo gedit mount

Add this text to make the ‘mount’ script

#!/bin/bash
#
# nautilus-mount-iso
gksudo -u root -k /bin/echo “got r00t?"
sudo mkdir /media/"$"
if sudo mount -o loop -t iso9660 “$” /media/"$"
then
if zenity –question –title “ISO Mounter” –text “$ Successfully Mounted.
Open Volume?"
then
 nautilus /media/"$” –no-desktop
fi
exit 0
else
sudo rmdir /media/"$"
zenity –error –title “ISO Mounter” –text “Cannot mount $!"
exit 1
fi

Now make the umount script
$ sudo gedit umount
and here is the code

#!/bin/bash
#
for I in “$"
do
foo=gksudo -u root -k -m "enter your password for root terminal<br />access" /bin/echo "got r00t?"
sudo umount “$I” && zenity –info –text “Successfully unmounted /media/$I/” && sudo rmdir “/media/$I/"
done
done
exit0

Set the files as executable

$ chmod 755 mount umount

This should have added the two new scripts to the context menu. Thanks to animacide @ ubuntu forums.

Install gMount

$ sudo apt-get install gmountiso

While it’s good to know the other methods this one is by far the easiest to use. Thanks gMount

Essential Ubuntu Apps

Mon, 04 May 2009 00:07:00 +0000

This is the distilled version of Lifehacker’s recent Top 10 Ubuntu apps.

Yakuake yakuake.kde.org

A handy console app, just hit F12 (or what ever key you configure the shortcut to) and a console drops down from the screen top aka Quake style.

sudo apt-get install yakuake

Gnome DO do.davebsd.com

Great keystroke launcher, has loads of plugins (such as google contacts, google docs etc) and can index a small (<3000)>$ sudo gedit /etc/apt/sources.listpaste this text to the end of the file and save

deb http://ppa.launchpad.net/do-core/ppa/ubuntu jaunty main
deb-src http://ppa.launchpad.net/do-core/ppa/ubuntu jaunty main

add the keys

$ gpg –no-default-keyring –keyring /tmp/gnome-do.keyring –keyserver keyserver.ubuntu.com –recv A5D19FDCAA6ABB440CD3464628A8205077558DD0
$ gpg –no-default-keyring –keyring /tmp/gnome-do.keyring –export –armor A5D19FDCAA6ABB440CD3464628A8205077558DD0 | sudo apt-key add -
$ rm /tmp/gnome-do.keyring

then install it

$ sudo apt-get update && sudo apt-get install gnome-do

Ubuntu Tweak ubuntu-tweak.com

Handy GUI with loads of settings that you would have otherwise never known about.

$ sudo apt-get install ubuntu-tweak

That’s it for now, they are all very handy.. whats next?

Still waiting for S-Video out support for my ATI graphics card.. fglrx is not an option at the moment
Testing out open office to be sure I know how to use all the features I used to use in MS office before making the big switch.. TOCs in text citations etc
Might have to test out a windows emulator just incase.. looking at Wine winehq.org or VirtualBox virtualbox.org

Upgraded to Ubuntu 9.04... Initial issues

Fri, 24 Apr 2009 07:57:00 +0000

Used the ‘Update Manager’ to get the new distro, 9.04 Jaunty Jackalope (Must be a relative of the Wolpertinger)

Initial thoughts

Xserver crashed on re-boot, fixed this by completely removing fglrx and reinstalling some xserver packages packages

sudo apt-get remove –purge xorg-driver-fglrx
sudo apt-get install –reinstall libgl1-mesa-glx libgl1-mesa-dri
dpkg-reconfigure xserver-xorg

Found this info at https://wiki.ubuntu.com/X/Troubleshooting/FglrxInteferesWithRadeonDriver thanks go to Nesta Campbell

Ubuntu logo is much smaller! which looks kinda cool on my small laptop screen
Xserver running slow

Applications showing loads of lag
Closing windows often gives “Not responding.. Force Quit | Wait”

What’s next

Get a working fglrx installed so my S-Video out works agian (although I didn’t test this function yet in 9.04, but S-Vid didn’t work under 8.10 without the proprietary ATI driver)
See if I can finally get the ‘xinerama’ option to work for my two screens (Laptop Screen and TV) or at the very least run them as two ‘independent screens’ as opposed to clone screens, which was the only working option (after hours and hours of fruitless xorg fiddling) under Ubuntu 8.10

Just forget about Doom2

Mon, 07 Feb 2005 22:22:00 +0000

It is a dark day, after trying long and hard to fix my flatmates laptop I have to admit defeat. Trying to install an OS on a computer with no working floppy drive or CD drive is not easy. I was encouraged by the Boot to LAN - with PXE option the 3Com LAN card gave on start up. But after many hrs of trying to set my PC up as a DHCP/TFTP linux server to remote install the OS, I realised;

Budapest is a cool place

I know nothing about programming, I should have never bothered messing around with Linux, I was only guessing that the hard disk wasnt completely fried and it is probably time for a new laptop anyway. I realise that all this open source stuff must be a great idea but the amount of time and effort required, for someone who has only ever used MS-DOS and Windows, is kinda inhibitory. I was bored last week and printed off this great article that I have slowly been reading, its entertaining stuff..
“In The Beginning There Was The Command Line” read it here
originally written by Neal Stephenson but more recently updated by a code-monkey named garrett who gives its a bit of a fresh perspective..
