Viewline has been designed to enable the use of a wide range of video encodings augmented by software.

Depending on the version of Windows that you are using and the other software that you have installed on your system you will have a number of codecs made available to DirectShow applications via filters. In fact each time you install a video application on WIndows it will normally install with it a collection of filters to support encoding and decoding video. The free and open source distributions detailed below are recommended to gain the best functionality from Viewlines video component. All rights and liability in the below software are owned by their respective developers, and not Viewline.

  • Haali Media Splitter provides mkv support and automatic solutions to several MPEG encoding issues.
  • K-Lite Codec Pack is a collection of components needed for audio and video playback in DirectShow players such as Windows Media Player, Media Center, and Media Player Classic. It contains everything you need to play all common audio and video file formats

Viewline supports Direct Show filters

Viewline uses DirectShow for capturing, converting and playing video. DirectShow is a Windows technology that supports a wide range of codes and formats through the installation of filters. When you install a DirectShow filter it is normally available to all media aplications on Windows.

Open source and distribution

Many video encodings especially those of the MPEG, and emulations of these formats provided by open source projects such as DivX or XVid cannot be distributed with Viewline due to licensing restrictions. However you can install these codecs and in the case that they provide a DirectShow filter, Viewline will be able to use them.
