LAV Filters 0.81 Final

Built on the powerful libavformat and libavcodec libraries from the ffmpeg project, these tools enable playback of almost any format when used with a compatible DirectShow player.

Key Features in LAV Filters 0.81

Broad Format Compatibility
LAV Filters support decoding for numerous formats, including H.264, HEVC, VP9, AAC, AC3, EAC3, DTS (-HD), TrueHD, and many others.

Hardware Acceleration
With support for DXVA2, NVIDIA CUVID, and Intel QuickSync, LAV Filters offload decoding tasks to your hardware, reducing CPU usage and improving performance.

Bitstreaming
The filters can pass audio streams like Dolby Digital and DTS-HD directly to your AV receiver, maintaining high-quality sound.

Installation Tip

Before installing LAV Filters, make sure to uninstall Haali Media Splitter or rename its AX file. Haali tends to override player settings and may conflict with LAV Filters, preventing them from taking priority.

Not all containers are equally supported, so some formats might work in one container but fail in another.

Keep in mind that "tested" doesn’t guarantee it won’t fail at some point. With so many codec combinations, it’s impossible for developers to test them all.
