K-Lite Codec Pack

As previously discussed in the Tip of the Night for December 7, 2019, a video may not play in an application or on an operating system, unless the necessary codecs are installed. A codec will uncompress a video file, so it can be played. Typically video files are compressed to save storage space at the loss of some of the original resolution. These are lossy video files.


The K-Lite codec pack, available here, https://codecguide.com/, will allow Windows to play a wide range of video and audio formats. It should allow Windows Media Player to recognize most video and audio files. The Ogg video format (with an .ogg, .ogm or .ogv extension) is actually a container file which must be uncompressed before it can be played. It is not supported by Windows Media Player. See the list of supported files posted here. If you attempt to play such a file in Windows Media Player, you'll get an error like this:


If you prompt the Windows Media Player to try it, you'll get this result:


After the K-Lite Codec Pack is installed, an OGG file should play in Windows Media Player. I tested this on my PC tonight and confirmed that installing the pack made the difference.


Another common format video format which doesn't work with Windows Media Player is are Adobe Flash videos with the .flv extension.


However, if you are presenting videos with IPRO's courtroom presentation software Trial Director ,be aware that the K-Lite codec pack can cause problems. Tech support for IPRO warned me last month that the K-Lite codec pack has been known to interfere with the performance of Trial Director. It's usually recomnended that Windows Media Player be set as the default application for video and audio files when using Trial Director.
