HandBrake (32-bit)

What's new in this version:

Encoders:

Video:
- updated libx264 (revision 2146)
- MPEG-2 encoder (from libavcodec)
- advanced options support for libavcodec encoders format: option1=value1:option2=value2 -bf 2 -trellis 2 becomes bf=2:trellis=2

Audio:
- audio gain control (increase/decrease audio volume)
- updated libogg (1.3.0) and libvorbis (aoTuV b6.03)
- new AAC encoder (from libavcodec) (considered experimental) (supported mixdowns: Mono/Stereo/Dolby?, 5.1 will come later) (should be on par with faac in terms of quality, sometimes better)
- FLAC encoder (16-bit, MKV container only)
- Mac OS X: HE-AAC encoding support, via Core Audio
- quality-based variable bitrate encoding support works with: Lame MP3, Vorbis, Core Audio AAC only implemented in CLI and Linux GUI
- AC3 encoder: set Dolby Surround flag in stream parameters when mixdown is Dolby Surround or Pro Logic II

Audio Passthru:
- DTS Passthru to MP4 container (in addition to MKV) (supported by e.g. VLC, MPlayer)
- DTS-HD Passthru (MP4, MKV containers)
- MP3 Passthru (MP4, MKV containers)
- AAC Passthru (MP4, MKV containers) (known issue: Magic Cookie not passed through from MPEG Program/Transport? streams,which will break playback in e.g. QuickTime Player)
- Auto Passthru: one encoder, multiple codecs lets you define allowed codecs (from supported passthru codecs) lets you pick a fallback encoder if passthru is not possible

Muxers:
- start MKV clusters with a video keyframe whenever possible should improve seeking and DLNA streaming
- bug fix: use ISO 639-2 bibliographic form for MKV language codes
- bug fix: fix crash due to division by zero in MP4 muxer

- updated libav* libraries from Libav ( http://libav.org/) (v0.7-1696-gcae4f4b, late October 2011) frame-based multithreading for H.264, VP8 10-bit decoding support for H.264, DNxHD Apple ProRes? decoding support
- improved average framerate detection
- duplicate frame detection for improved frame drop decision (CFR/PFR)
- new Same as source, Constant Framerate option for devices that don't support variable framerate automatically picks a constant framerate closest to the detected average framerate
- bug fix: fix problem when resolution changes in the middle of a video stream

Audio:
- Blu-ray: make TrueHD, DTS-HD and E-AC3 Secondary Audio streams available for decoding and/or passthrough
- bug fix: libavcodec-decoded streams can now be decoded multiple times previously, multiple decodes of the same source tracks weren't possible and audio output tracks had to be dropped
