Software Update: LAV Filters 0.65

Version 0.65 of the LAV Filters has been released. The LAV Filters are a collection of open source DirectShow filters, which allow the most common formats of audio and video to be played in a media player of your choice. It is part of the K-Lite Codec Pack and the Combined Community Codec Pack, among others. There are also media players, such as Media Player Classic – Home Cinema and VLC Media Player, which already have it on board. In version 0.65 the following changes and improvements have been made:


  • Installer: The installer does now backup DirectShow registry settings before overwriting them, allowing uninstall to restore them

LAV Splitter

  • NEW: Support for ProRes in MKV
  • Fixed: Opening AviSynth scripts with LAV Splitter which used DirectShowSource to load LAV Splitter again caused a deadlock
  • Fixed: Audio-only AviSynth scripts did not show a duration.
  • Fixed: Cue Sheets with directives with empty parameters could cause a crash

LAV Videos

  • Fixed: AVC1 video streams without SPS/PPS in the configuration record did not decode properly
  • Fixed: Decoding H.264 streams with a resolution change using the DXVA2 Copy-Back decoder could crash
  • Fixed: YUV->RGB conversion produced the wrong output for the last line of odd-height 4:2:2 or 4:4:4 files

LAV Audio

  • Changed: LAV Audio offers more alternate output configurations to the audio renderer if the audio renderer refuses our preferred format.
  • Fixed: Decoding AC3 audio with corrupted audio frames could cause unnecessary format changes to occur and disrupt playback
  • Fixed: Decoding DTS audio on a CPU without SSE2 support could crash on some streams
