KMPlayer has changed a bit since we reviewed version 3.2 back in May. KMPlayer has always been popular and familiar software, so the latest version might be a bit of an eye-opener -- in good ways and bad. One of the new additions, "KMP Plus," acts as a dashboard for the program. On startup, users are greeted by an interactive home screen where they can watch promoted videos and advertisements, browse video channels, or access their own library content directly.

KMP Plus is attempting to become a premium service, but this 3.4 release highlights what seems … Read more

The Internet Engineering Task Force has standardized the Opus audio compression technology as RFC 6716.

The move paves the way for much broader use of Opus for anything from playing music to online voice chats. Opus is what's called a codec because it defines how to encode and decode a stream of data for more efficient storage or transmission.

"Opus is the first state-of-the-art, free audio codec to be standardized. We think this will help us achieve wider adoption than prior royalty-free codecs," Jean-Marc Valin, a Mozilla employee and author of Opus, said in a blog post today. … Read more

If you've ever tried to compress a video file, you know that such files are already pretty dense and don't have much room to compress further, and also that video playback quality tends to suffer the more a file is compressed. But that doesn't mean you don't have options when you need to compress video for storage or bandwidth needs. XviD Video Codec is a free, open-source MPEG-4 codec that's specifically designed to maximize compression without sacrificing video quality. Its algorithms remove the parts of a video file that don't affect the viewer's … Read more

A new compression technology represents a significant improvement over today's standard, a new study found. The result could help pave the way for video with at least four times the pixels of today's 1080p standard.

The new compression technology, called HEVC or H.265, is significantly better than today's prevailing standard video codec, called AVC or H.264, researchers from the Ecole Polytechnique Federale de Lausanne in Lausanne, Switzerland, concluded.

"The test results clearly exhibited a substantial improvement in compression performance, as compared to AVC," the researchers said. "As ultra-high definition television has recently … Read more

A trade show in September will be the coming-out party for video technology called HEVC or H.265, a new arrival in a hotly contested market for the best approach to compression.

HEVC, short for High Efficiency Video Coding, is for encoding and decoding video streams so they can be stored or transmitted more economically than today's dominant H.264, aka AVC or Advanced Video Coding. Specifically, HEVC allies say it can deliver the same quality video as H.264 with half the network bandwidth.

The codec has been in the making for years, but it's now almost … Read more

For more than three years, Skype has worked to improve online audio through involvement in a project now called Opus. But perversely, Skype's new owner, Microsoft, is undermining Opus just as a Web standards effort is poised to carry it into the mainstream.

Opus is an audio "codec" -- technology to encode and decode media streams for efficient transmission over the Internet or storage on computing equipment. Opus backers besides Microsoft's Skype division include Google, Opera, and Mozilla.

Opus has a lot of potential to improve online audio, something that's increasingly important as more communications … Read more

The only thing cooler than free media players might be the free codecs that improve playback quality or enable more file types. There are so many to choose from that it's often hard to know which is best, especially when there's more than one or two choices, like for MP3s: LAME, FLAC, AC3, and so on. JockerSoft's CodecInstaller is a free tool that scans your system, identifies your media players, and suggests codecs for them that can expand or improve their capabilities.

CodecInstaller's compact, vertically oriented interface has three main controls, each self-explanatory: Installed Codecs, Analyze … Read more

The good news is, VLC Beta was released today, giving Android users a long-awaited taste of do-it-all media player VLC. The bad news is, VLC's developers say the app is meant only for power users and hackers, meaning most of us should probably wait on downloading it.

Just like its bigger brothers on Mac and Windows, VLC is a free and open-source multimedia player that can open just about any media file out there. It offers an audio and video media library with full search capabilities, and supports subtitles and network streams, including HLS.

While VLC Beta is available … Read more

K-Lite Codec Pack is a free package of media player codecs that can improve both audio and video playback in Windows Media Player or the included free Media Player Classic. It includes many components but has a single installer and setup tool.

K-Lite Codec Pack's installer offers three options: Simple mode, which hides most options and uses recommended defaults; Advanced mode (the default setting), which shows almost all options; and Expert mode, which unlocks additional options. Well, we couldn't resist Expert mode, especially since our biggest concern was having existing codecs displaced or replaced by new but possibly … Read more
