When a video file has no sound or a media player cannot recognize its format, K-Lite Codec Pack Mega adds codecs and filters for playback in Windows applications. The bundle includes MPC-HC, a player with seekbar previews, and tools for managing installed codecs.
Codec and format coverage
The pack adds decoding support for a broad range of audio and video formats, including MKV, MP4, AVI, WebM, FLAC, Opus, and ALAC. Supported video codecs include H.264, HEVC, VP9, AV1, MPEG-2, and ProRes; audio support includes AAC, AC3, DTS, Vorbis, and TrueHD. Hardware-accelerated decoding is available for common video formats on compatible systems.
Installed codecs can work with DirectShow-compatible players, so playback support is not limited to the included MPC-HC. The installer offers component choices, while a utility included in the pack configures and manages codecs already installed on the system.
What can MPC-HC do?
MPC-HC provides an included playback option for files handled by the pack. Its seekbar can show video previews while scrubbing, and the player has a dark theme. It can also stream video from sites such as YouTube and Twitch when yt-dlp.exe is placed in the MPC-HC folder.
For HDR playback, MPC-HC can use the included MPC Video Renderer or madVR. The included MPC Video Renderer also supports Dolby Vision, while madVR offers high-quality video upscaling. Blu-ray disc playback is supported, but disc menus are not.
Playback tools and file browsing
A thumbnail utility generates previews for video files in Windows Explorer, making it easier to identify clips in a folder without opening each one. The codec management utility provides controls for the installed components, which is handy when diagnosing playback behavior or adjusting the system's media setup.
- Use MPC-HC to preview a video while moving along its seekbar.
- For protected Blu-ray discs, playback also requires a separate tool that removes AACS protection.
