LAV Filters (formerly LAVFSplitter) is a collection of DirectShow media splitters and audio/video decoders that allow you to play a wide range of media formats.
They are based on libavformat and libavcodec libraries from the ffmpeg project, which means that you can play almost any format as long as you use a DirectShow player.

The LAV filters package contains an audio decoder, a video decoder and a multi-format media splitter which work together for hassle-free playback every time.

It contains the following video codecs: H264, VC-1, MPEG-2, MPEG4-ASP (Divx/Xvid), VP8, MJPEG etc.; the audio codecs it provides you with are AAC, AC3, DTS (-HD), TrueHD, MP3/MP2, Vorbis, LPCM etc. and it also offers support for VOB, DVB Subs, PGS, SRT, SSA/ASS and text subtitles and for Blu-rays.

A precaution you need to take when installing LAV Filters on your computer is to uninstall the Haali Media Splitter or rename its AX file, as it forces all players to use it and it denies priority to LAV Filters.

LAV Filters also has demuxing capabilities; it can demux sub-streams and media files into their elementary streams so you can play Blu-rays on your computer.

Moreover, the video component of this virtual item supports multi-threading, hardware and software deinterlacing and it allows hardware acceleration as well.

The audio decoder offers support for bitstreaming via HDMI and S/PDIF to the receiver with audio-video synchronization and audio delaying options.

Lately, LAV Filters provides support for VP7 videos and it has implemented a WMV9 MFT decoder that replaces the old DMO decoder for VC-1/WMV3 on Windows 7 and above.

All things considered, LAV Filters is a great addition to your system, as it ensures excellent media playback and it uses a low amount of your system resources. Once you install it on your computer, you can play virtually any media content.

Changes in LAV Filters 0.64:

* General
- NEW: Individual LAV Filters can now be blacklisted through the registry by creating a key with the executable name in HKCU\Software\LAV\\Blacklist
* LAV Splitter
- NEW: Support for RTMP using rtmpdump-style parameter syntax
- NEW: Support for Opus-in-TS
- Fixed: The language reported for audio/subtitle streams on some Blu-rays could be wrong
* LAV Video
- NEW: HEVC Main10 decoding in DXVA2 Copy-Back mode
- Faster: DXVA2 Copy-Back in direct output mode uses up to 50% less CPU and performance is improved accordingly
- Fixed: H.264 streams with only DTS timestamps would play out of sync with DXVA2
- Fixed: DXVA2 could crash on some MPEG-2 streams
- Fixed: Improved compatibility with a few HEVC streams when using DXVA2

IMPORTANT!
- Not all containers are equally supported, so some formats may fail in one container and work in another.
Also note that "tested" doesn't mean it won't fail eventually. There are many combinations of codecs, and its impossible to test all of them for developer.
