Free high quality youtube software for linux

QAA is a XUL Mozilla Firefox extension that performs a user supplied test list on a Web application. Test sessions can be defined by example.
A report is generated when sessions are replayed.
Enhancements:
- This release can load and save .qaa files (Quality Assurance Agent file format), record a journey in the tested site using definition by example, and perform a test bench with a log style report.

Audiality is a scalable and portable audio engine for music and sound effects. It is intended to play equally well in studios and inside games, in order to serve as a flexible tool for content creation, and for use in the final product.

Audiality uses MIDI files in combination with scripting and modular synthesis, to minimize file sizes and maximise flexibility. It is very portable, and supports both integer and floating point processing modes.

Scalability has been a major priority from the start. The current version will run on very low end Pentium systems, but can also produce high quality audio on more powerful hardware.
The main goal for the future is to extend the scalability of Audiality well into the range of serious home and professional studio use. The idea is to provide total control, a wide range of features, tools for fast and effective creation of original sounds, and excellent audio quality.

WebService::YouTube is a Perl interfece to YouTube.

SYNOPSIS

use WebService::YouTube;

my $youtube = WebService::YouTube->new( { dev_id => YOUR_DEV_ID } );

# Get videos via REST API
my @videos = $youtube->videos->list_featured;

# Get videos via RSS Feed
my @videos = $youtube->feeds->recently_added;

SimCList project is a high quality C library for handling lists.
SimCList is available for free, under restrictions imposed by the BSD license.
SimCList API is good because:
- it is simple, yet powerful
- it makes elegant and consistent use of information hiding
- it abstracts the actual data type to store
- it is fairly total
The library itself is very performant and makes a good compromise between performance in terms of time and space:
- insertion is O(n) [typically n/8]
- extraction and deletion are O(n) [typically n/8]
- iteration is O(1)
- sorting is always O(n logn), without worst case
Thread safety
The SimCList library is thread safe, meaning that many threads can run SimCList operators on different lists concurrently without hurt, or also read operations on the same list.
However, of course, no safety guarantee is made for performing concurrently write+write or read+write operations on the same list (eg: insertion, deletion, sorting, ...). For performance and portability reasons, protecting such operations from concurrency is left to the library adopter.
Performance
SimCList has been designed with ease to use and performance in mind. There is some example factors that have been taken into account, and against which the code has been optimized when implementing SimCList:
- overhead of function calls
- cache locality
- number of branches, possible CPU stalls or pipeline flushes
- dynamic memory allocation weight on the OS
- other mathematic/probabilistic optimizations for avoiding worst-case or improving average case behaviours in algorithms
Many parts of SimCLists code have been deeply improved with profiling analysis.
Enhancements:
- Transparent inclusion in C++ applications is natively supported.
- Sentinels are used to improve performance on list traversals.
- A problem was fixed with list_insert_at, which could output inconsistent lists when inserting into even-sized lists in position 0.

3ivx is an MPEG-4 toolkit that supports MPEG-4 Video, MPEG-4 Audio and the MP4 file format. 3ivx D4 4.5 allows video and audio to be compressed to a fraction of its original size while maintaining high image quality.

You can store over 2 hours of near DVD quality audio and video on a single CD-ROM or stream near DVD quality video over a cable modem or DSL modem.

Supported File Formats:

- Input Files: 3GP, AAC, DivX, MOV, MP4
- Output Files: AVI, MOV, MP4

Why should I install 3ivx?

The 3ivx decoder plays back most MPEG-4 files (including MP4, M4A, 3GP and MOV files) with MPEG-4 AAC Audio and MPEG-4 Video (such as DivX 3, 4 and 5, Apple MPEG-4, Philips MPEG-4 and XviD) using Windows Media Player or other compatible players. The Audio Decoder can play back MPEG-4 Multi-Channel High Efficiency AAC including audio encoded by Nero AAC and iTunes.

The 3ivx encoder produces industry-leading compact high quality MPEG-4 Audio and Video and is distributed as a plug-in for QuickTime as well as plug-ins for Video for Windows and DirectShow.

This allows you to encode MPEG-4 Audio and Video in AVI, MOV or MP4 files with the encoding application of your choice.

Because of its core design and optimization the 3ivx codec maintains a record-breaking speed.

3ivx Delta 4 - 4.0.3 plays back DivX 3.x, 4.x, 5.x, OpenDivX, XviD, FFMpeg, AngelPotion, SMR, Philips MPEG-4, Apple MPEG-4, MS-MPEG-4v3, 3ivx D3, D3.5 and 4, RealMagic MPEG-4, Sorenson MPEG-4, Blizzard MPEG-4 and other MPEG-4 variants.
