How To: Greek subs in mplayer

In order to be able to  use the following solution you should install two packages msttcorefonts and mplayer-fonts. The procedure is applied in Debian and Ubuntu, but with some mods it is applicable to all linux distros.

# aptitude install mplayer-fonts msttcorefonts

The all you have to do is to test using the command line that everything is alright

$ mplayer -subcp ISO-8859-7 movie.avi

Properly, you should be able to see the greek subs. In order to make the changes permanent we now have to edit the config file located usually at $HOME/.mplayer/config.
Just open the file with your favorite editor and append the following

# Write your default config options here!
# Set font encoding.
# Set font.
font=/usr/share/fonts/truetype/msttcorefonts/arial.ttf

# Set font encoding.
subcp=ISO-8859-7

# Set subtitle file encoding.
unicode=yes
utf8=yes

Anycast DNS

What is Anycast ?

The basic idea is extremely simple, multiple instances of a service share the same IP address. The routing infrastructure directs any packet to the topologically nearest instance of the service. It has been the basis for large-scale content distribution networks since 1995. In the bottom line is just a configuration methodology that is gradually taking over the core of the DNS infrastructure, as much as the edges of the WWW.

The following article is a quick guide on the building of a anycast cluster based on Linux and Quagga routing suite.

VP8 the new opensource video standard for web

WebM Project

is dedicated to developing a high-quality, open video format for the web that is freely available to everyone.

WebM is an open, royalty-free, media file format designed for the web.

WebM defines the file container structure, video and audio formats. WebM files consist of video streams compressed with the VP8 video codec and audio streams compressed with the Vorbis audio codec. The WebM file structure is based on the Matroska container.

This is the Open Source Project supported by Google and many more companies dealing with the development of the VP8 video codec for use in Web. Google is planning on proposing VP8 for HTML5 Video [via].

CFP: Intl. Journal of Communication Systems (IJCS) SPECIAL ISSUE ON Advances in Multimedia Communications

------------------------------------------------

Call for Papers

Intl. Journal of Communication Systems (IJCS)

SPECIAL ISSUE ON

Advances in Multimedia Communications

------------------------------------------------
Paper Submission Deadline: May. 1, 2010
Overview
Recent advances in communications technologies have witnessed a growing and evolving multimedia content delivery market based on information gathering, manipulation, and dissemination. It is a fact that personal communications, computing, broadcasting, entertainment, etc. have turned into streams of multimedia content, and the various communication and network technologies have become the means to carry that content to a wide variety of terminals. Unlike traditional communication systems, a fundamental challenge for present and future communication systems is the ability to transport multimedia content over a variety of networks energy-efficiently at different channel conditions and bandwidth capacities with various requirements of quality-of-service. There are many issues need to be addressed such as signal processing, collaborations, power management, flexible delivery, specialization of new content, dynamic access, telecommunications, networking, etc., due to the multi-disciplinary nature of the applications in advanced multimedia communications.
The goal of this issue is to bring together the state of the art research contribution that
describes original and unpublished work addressing the new emerging techniques on multimedia communications. Especially, we solicit research papers on addressing challenging issues existing for enabling mobile multimedia communications over heterogeneous infrastructure for realizing next generation networking and computing, e.g., 4 G all IP networks, ad hoc networks, wireless sensor networks, ubiquitous computing environments, cognitive radio networks, etc. For example, ubiquitous multimedia is a requirement in next generation networks, such as multimedia adaption in wireless network; multimedia services in ubiquitous circumstance; improving distributed multimedia communication through location awareness, action awareness, user awareness, etc. On the other hand, due to the limited computational power, memory and battery energy in wireless and portable terminals, power efficient design also plays important role in next generation mobile multimedia applications.
Topics
Topics of interest include, but are not limited to, the following scope:
*New emerging multimedia applications and architectures
- Enabling multimedia capability in E-healthcare, Smart house etc.;
- Wireless sensor system for video surveillance
- Mobile and multimedia communications in sensor networks
- Ubiquitous and ‘green’ multimedia design next generation networks
*Video communication over next generation networks
- Energy efficient and scalable control in next generation wireless video terminals
- Cost effective and low power video coding design in wireless networks
- Frontiers in game theory and multimedia systems
- Distributed video coding and dissemination in wireless networks
*Emerging technologies for multimedia communications
- Multimedia communications in new emerging systems
- Resource allocation in energy-constrained wireless multimedia networks
- Collaborative in-network processing;
- Cross-layer design for multimedia communications;
- Distributed coding and joint source-channel coding;
- Error resilience and concealment;
- Resource allocation and system scheduling;
- Multimedia security.
Important Dates
Paper Submission Deadline: May. 1, 2010
1st Notification of acceptance: Aug. 1, 2010
Submission due date of revised paper: Sep. 1, 2010
2nd Notification of acceptance: Oct. 15, 2010

Submission Papers are solicited for the special issue, guidelines for preparation of the manuscripts, are provided at the International Journal of Communication Systems website,
http://www3.interscience.wiley.com/journal/117946196/grouphome/ForAuthors.html.
The authors need to submit their papers online while sending a cover letter to all of the
guest editors. The cover letter must include paper title, abstract, the corresponding
author's name and affiliation. The "Subject field" of the email must contain
"IJCS Multimedia Paper - ". All papers will be rigorously reviewed based on the quality:
originality, high scientific quality, organization and clarity of writing, and support
provided for assertions and conclusion.
