  • Bugfixes
  • Important security fix: Buffer overflow vulnerability was fixed
  • Fixes to ffdshow's remote API
  • GDI resource leak fix
  • Subtitle fixes:
  • Fixed missing character at the end of line with non-UTF8 encoding in embedded subtitles
  • When activating SSA tags within SRT subs, default placement (with no tag) was not correct
  • Subtitle stability fix for random crashes
  • Workaround for crashes in applications that use the Windows Media Player SDK
  • Wrong color fix for Fraps v5
  • The Grab filter was producing a black right border when saving PNG images having a width which was not a multiple of 16

  • New deinterlacer: yadif (Yet Another DeInterlacing Filter)
  • Updated libavcodec with the latest code from the FFmpeg project
  • Volume normalization:
  • One-pass normalization added. This mode is used to reach the highest possible loudness with minimum of possible artifacts
  • Improved normalization, the probability of clipping has been decreased
  • Added support for S/PDIF sample rates other than 48kHz: Pass-through of 44.1kHz AC3/DTS streams plays back correctly now
  • Dynamic range compression level for AC3 and E-AC3 sources can now be set between 0 and 100%
  • AC3/DTS pass-through settings are now based on presets

  • Support H.264 digital television playback in DVBViewer
  • Improved H.264 seeking
  • Added an option to deinterlace only frames flagged as "interlaced"
  • Enhanced interlacing options allow to choose the method (auto, weave, bob) as well as the field order (auto, top field, bottom field)
  • Color space conversion: Added option "Force progressive" and "Force interlace"
  • Flag telecined frames as progressive (libmpeg2)
  • H.264: Correct field order, interlace/progressive flags are decoded
