XviD

XviD is an ISO MPEG-4 compliant video codec, so designed to compress/decompress digital video.

XviD is a open source project, which is developed and maintained by a handful of skilled and interested engineers from all over the world.

This release is the long awaited 1.1.0. It is mostly API compatible with the previous stable release as we dropped support for reduced resolution coding. If your application didn't use that feature then the upgrade is totally compatible.

What is new in this release:

• xvidcore library:
• Updated implementation of IDCT/FDCT to match error spec of MMX/SSE code
• Added "make info" to unix Makefile
• Removed debian directory from release tarballs
• Made multi-threading (pthread support) switchable at compile time
• VFW frontend:
• Minor GUI changes
• DShow/MFT frontend:
• GUI cosmetics
• Updated MSVC project files with seperate build configs for MFT-enabled binary

What is new in version 1.3.1:

• xvidcore library:
• Enabled noexec stack for both elf and elf32 obj format for better NASM compatibility
• Fixed edging bug for non-mod16 image dimensions
• Generated configure scripts with more up-to-date autconf version
• Fixed error with pthread check in configure.in script
• DShow/MFT frontend:
• Disabled rgb_flip for MFT decoder
• Modified icon/gui graphics for better visibility
• Changed VC8 project files to use static LIBCMT runtime

What is new in version 1.3.0:

• xvidcore library:
• Disabled late-promotion of S_VOP to N_VOP coding type
• Makefile fixes for macho64 target
• VFW frontend:
• Minor GUI cosmetics
• Decoder support for lower-case FourCCs
• Fix for YV12 colorspace pass-through mode
• DShow/MFT frontend:

• Decoder threads API extension
• PSNR-HVS-M as optional D-metric for R-D optimizations
• Noexec-stack security patch also for x86_64 asm code
• Added new slice coding feature
• App-level encoder multi-threading support (xvid_encraw)
• Signalling of FourCC to decoder for better bug detection
• Changed semantics of frame_drop ratio API option
• Improved decoder robustness on resync markers in BVOPs
• VFW frontend:
• Increased allowed max bitrate
• New 'HD 1080' preset
• Added new MPEG4 simple profile levels
• VHQ metric GUI option
• Independent slice coding widget
• Selectable adaptive quantization method
• Fix for handle leak problem
• Minor GUI cosmetics
• DShow/MFT frontend:
• Tray icon to access filter properties
• Added MFT API support
• Shared cpu_flags/num_threads settings with VfW

What is new in version 1.2.2:

• xvidcore library:
• Workaround for nasm bug with Mach-O/OSX target
