How to Watch Live Streams on Ubuntu via Your Favorite Video Player

Last updated: September 8, 2013

Want to watch live streams on Ubuntu via your favorite video player? Well, here’s how to do it using Livestreamer which supports most of the big streaming services such as Dailymotion, Livestream, Twitch/Justin.tv, YouTube Live, UStream.

Livestreamer is a Command Line Interface that pipes video streams from various services into a video player, such as VLC, Mplayer. The main purpose of Livestreamer is to allow the user to avoid buggy and CPU heavy flash plugins but still be able to enjoy various streamed content.

There is also an API available for developers who want access to the video stream data.

It’s very easy to use this tool. Let’s say you want to watch the stream located on http://twitch.tv/day9tv, just run below command in terminal (press Ctrl+Alt+T to open it).

livestreamer twitch.tv/day9tv

[cli][info] Found matching plugin justintv for URL twitch.tv/day9tv
Found streams: 240p, 360p, 480p, 720p (best), mobile_high, mobile_low (worst)

It will find out what streams are available and print them out for you to choose from. Simply give livestreamer the stream as the second argument and playback will start in your video player of choice.

In this case the best stream is a reference to the stream that is considered to be of highest quality, e.g 720p. The –player argument will specify the video player (It will open VLC as the default player if not specified).

livestreamer twitch.tv/day9tv best --player mplayer

Install Livestreamer in Ubuntu, Linux Mint

Press Ctrl+Alt+T on your keyboard to open terminal. When it opens run below commands to install pip installer:

sudo apt-get install python-pip

Then install Livestreamer via pip:

sudo pip install livestreamer

This will work on all current supported Ubuntu releases, include Ubuntu 13.10, Ubuntu 13.04, Ubuntu 12.10, Ubuntu 12.04, Ubuntu 10.04 and their derivatives such as Linux Mint and Elementary OS.

Choqok 1.4 Now Supports for Twitter API v1.1: Install it in Ubuntu

Last updated: September 5, 2013

The Choqok micro-blogging client has updated to version 1.4 which brings back the Twitter support. Identi.ca support has been removed from StatusNet plugin.

The developer announced in the official website:

Sometimes ago we had two bad news, Identi.ca service switched to pump.io software and dropped it’s API, so Choqok is no longer support Identi.ca service, but it still supports StatusNet websites, because StatusNet is not died. About Identi.ca support, right now there’s no one working on pump.io support as I know, so unfortunately there’s no promise on supporting it again.
And in Twitter land, they turned off support for API v1.0 which Choqok was using, and so with this update Twitter support is back to Choqok.

other changes:

  • Support for Twitter API v1.1 (Thanks to Daniel Kreuter for his effort on it)
  • “mark timeline as read” menu item added to tabs context menu (Lim Yuen Hoe)
  • Show “in reply to” in twitter search timelines (Lim Yuen Hoe)
  • Identi.ca support removed from StatusNet plugin, we still support StatusNet
  • And some other minor fixes

Install Choqok 1.4 in Ubuntu:

Press Ctrl+Alt+T on your keyboard to open terminal. When it opens, run below commands to install the client in Ubuntu 13.10, Ubuntu 13.04, Ubuntu 12.10, Ubuntu 12.04 and their derivatives.

sudo add-apt-repository ppa:adilson/experimental

sudo apt-get update

sudo apt-get install choqok

Linux Kernel 3.11 Released: Install / Upgrade it in Ubuntu 13.04/12.04

Last updated: September 3, 2013

Linus Torvalds has announced the Linux Kernel 3.11. Here are the new features and how to install / upgrade new kernel in Ubuntu 13.04, Ubuntu 12.10, Ubuntu 12.04 and Linux Mint.

Linus Torvalds wrote on the mailing list:

As some people noticed, I got distracted (“Ooh, look, a squirrel..”)
and never wrote an announcement for -rc7. My bad. But it wasn’t
actually all that interesting a release apart from the date, and it
had a silly compile error in ohci-pci if you hadn’t enabled
CONFIG_PM_RUNTIME, so we’ll just forget -rc7 ever happened, ok?
Instead, go and get the real 3.11 release, which is out there, all
shiny and ready to be compiled and loved.

Since rc7 (ok, I lied, it happened) there’s been just small fixes.
Most of them came in from the networking tree, but there’s some all
over: some random filesystem fixes, a couple of sound fixes, a
/proc/timer_list fix, things like that. Nothing really stands out
(unless you happened to use the new soft-dirty code, that had a buglet
that could really hurt), but let’s hope we don’t have some silly
configuration that doesn’t even compile this time around.

Shortlog appended.

Linus

The Linux Kernel 3.11 Features:

Graphics:

  • The DRM driver changes dominate the Linux 3.11 kernel! The big feature is Radeon dynamic power management support has finally come to AMD’s open-source driver along with early support for the Radeon HD 8000 “Sea Islands” GPUs. Phoronix tests have shown Radeon DPM is successful at improving power use and lowering temperatures while delivering great performance.
  • There’s a new DRM display driver for the Renesas R-Car SoC.
  • Intel Haswell improvements and Valley View / Bay Trail support is now ready for Linux desktop usage.
  • H.264 / MPEG-2 video decoding for Nouveau with select NVIDIA GPUs bearing the VP2 engine as part of the PureVideo HD support. This is exposed in Gallium3D via the VDPAU state tracker. There’s also early GK110 GPU support. The NVIDIA GK110 is the firm’s latest high-end Kepler GPU.

Disk / File-System:

  • LZ4 compression support.
  • Zswap was merged for compressed swap caching.
  • Various XFS file-system improvements.
  • Performance tuning for Btrfs.
  • F2FS file-system updates.
  • EXT4 file-system updates.
  • The Lustre file-system client was merged for the first time.

CPU:

  • AVX2 Crypto optimizations.
  • PowerPC improvements from IBM.
  • Continued ARM improvements.
  • Xen and KVM virtualization now work for 64-bit ARM.

General Hardware & Miscellaneous Improvements:

  • Input device improvements.
  • Lots of audio / sound improvements.
  • With Linux 3.11, Wine can now handle Windows RT applications.
