These codecs play just about everything under the sun. If you can play it with, eg, MPlayer, VLC, or any other FFMpeg-based player, you can use this to play it with Windows Media Player, or any other DirectShow player.

Seriously, even BD decoding technology is included, although I haven't tested this. If you have a stubborn video that should play, but won't, this is the solution.

I have a 1080p Avi file and LAV Filter installed in a KMPlayer. It is choppy with this HD file but when switched back to use a divx 6.10 codec, it played well. This is the only time that I have problem with LAV

Its a wonderful filter for playing all kind of video and audio. Nvidia CUVID works flawlessly and its performance is just awesome. I feel now this LAV is better than ffdshow.

Highly recommended for the best playback.

i use this since lav cuvid decorder was integrated, it is great and awesome using nvidia cuda to decode many kind of files using all the power of your nvidia gpu, you can also use dxva on nvidia and ati-amd

really easy to use with media player classic HC, easy to setup,

the bad thing is that mpeg4 decode on cuda does not works, but is not a big problem, just disable it then the cpu will decode it

The LAV filters are really impressive and to me, they seem to work a heck of a lot better than the FFDshow filters.

I don't use the LAV Audio yet, because I'd like to see a few more interesting features added before I decide on using it. Otherwise, the filters are great and I plan on using them for a long time.

Definitely recommended.

This filter is excellent.
I have used it since I knew it several months ago.

Switching other splitter with this, most of the problems are solved, especially some video can\'t be played or no sound during playing, then switching the splitter with this.
This splitter works most of the format.

Really excellent!!!!
