November 2019 - LAV Filters are an open-source Direct Show audio-video filter wrapper, written by a very good german developer, of the FFMPEG libraries, focused on high quality direct playback. The trio (Splitter, Video Decoder and Audio Decoder) is reliable, stable, with really few bugs. Respect to the MPC-BE or Pot Player integrated filters, the LAV combo sometimes exhibit some issue when dealing with streaming video. But the developer explained that its filters are not really focused on the compatibility for online videos. Infact, for playing high quality video and audio files from disk, LAV Filters remain the most reliable combo, correct, a de facto standard for HTPC users on Windows enviroment. As usual, MPC-HC + LAV Filters + madVR (or EVR on Intel - Intel context adaptive scaling) remain the best tool to watch videos with Win 8 or Win 10.

This review is for new users. October 2019. LAV Filters is the only combo for splitter, audio and video decoding that I can advice. It's stable, reliable, focused on quality, on active development (by a great developer). The trio MPC-HC + LAV + madVR (video renderer) is the Gold Standard for the HTPC users on Windows platform.
