This is a snapshot release of SVN revision 2829. It is not stable code. It is unstable (and undocumented) development code which will one day lead to a stable release of HandBrake 0.9.4. But in order for that process to happen, it needs a lot more bug testing.

A full change log can be found on the Trac.
- Libx264 bumped to r1259-dd026f2, bringing with it the magic of macroblock tree rate control (mbtree) and a new CRF curve (meaning you will get different, generally lower bitrates at the same RF, with similar quality metrics). Mbtree is disabled when bframes=0 because of a minor bug with fades between camera shots. Can be enabled even then by explicitly putting mbtree=1 in the x264 option string
- Allow DVD sources with no audio
- Libdvdnav patched to perform read error recovery
- Libdvdread patched to allow raw device access in Windows
- Looks harder for aspect ratio info from DV sources
- Tweaks for packaging tools
- Use "utf-8" instead of "utf8" as the string format identifier for SRT
- Libtheora bumped to r16547
- Core audio sampling rate fixes
- Fixed 32-bit compilation in Snow Leopard
- Added 10.5 target for use in 10.6
- Use QTX for live preview
- Fixed EyeTV package scanning
- Cleanup / Improved some of the programs options. (Growl, use m4v, drive detection)
- Numerous fixes in the Picture Settings Panel and CLI Query Handling code.
- Several Fixes in the x264 panel related to 8x8dct
- Numerous Usability tweaks.
- Improved "auto" audio selection
- Use .m4v as the default extension for the MPEG-4 container
- Use .m4v when soft subs are enabled
- Decomb/deinterlace toggle
- Alternate angle encoding fix
- Only strips drive letters for Windows builds
- Show correct audio format info when it's been sanitized for incompatibilities
- Preserve chapter list modifications made to queued jobs
- Fixed error when navigating chapter titles with the keyboard
- Allow encoding sources with no audio without explicitly stating -a none
- Removed vestigial references to obsolete codecs and containers
As we've had on our roadmap for quite awhile now, one of our goals for version 0.9.4 is to refocus on HandBrake's key strengths and to remove dead weight. As part of this process, several presets, containers, and a codec have been removed from HandBrake.
* AVI: AVI is a rough beast. It is obsolete. It does not support modern container features like chapters, muxed-in subtitles, variable framerate video, or out of order frame display. Furthermore, HandBrake's AVI muxer is vanilla AVI 1.0 that doesn't even support large files. The code has not been actively maintained since 2005. Keeping it in the library while implementing new features means a very convoluted data pipeline, full of conditionals that make the code more difficult to read/maintain, and make output harder to predict. As such, it is now gone. It is not coming back, and good riddance.
* OGG/OGM: HandBrake's OGM muxer is just as out of date. It hasn't been actively maintained in years either, and it too lacks support for HandBrake's best features. It requires conditionals to work around missing functionality too...only this one gets tested so infrequently the conditionals were never even put in the code, so it just fails when you try to do anything advanced. This one is not coming back either. And yes, we're aware of HTML 5. For patent-free muxing, HandBrake still has Matroska.
* XviD: HandBrake, these days, is almost entirely about H.264 video, aka MPEG-4 Part 10. This makes it rather...superfluous to include two different encoders for an older codec, MPEG-4 Part 2. When choosing between FFmpeg's and XviD's, it came down to a matter of necessity. We need to include libavcodec (FFmpeg) for a bunch of other parts of its API, like decoding. Meanwhile, XviD's build system causes constant grief (it's the most common support query we get about compiling, after x264's requirement of yasm). Since we mainly use MPEG-4 Part 2 for testing/debugging, and recommend only H.264 for high quality encodes, Xvid's undisputed quality edge over FFmpeg's encoder is inconsequential, while FFmpeg's speed edge over XviD is important to us.
* Video game presets: There are no more presets for the PSP, PS3, or Xbox 360. Quite frankly, they didn't work well. None of the development team members own the devices, so testing was minimal and support was nonexistent. Keeping up with the firmware vagaries and ambiguous specifications of these devices was not fun -- we get enough of that from Apple's kit, and those we all have around to test on. The new "Normal" preset should work perfectly fine on any device that supports standard Main Profile H.264 with AAC-LC audio in an MP4 file, which the PS3 and 360 ostensibly do.
