Release Notes: A potential RGB24 access violation was fixed. A fix for a missing resync marker range check was made. A workaround for a nasm bug with the Mach-O/OS X targets was implemented. The precision for RGB<->YUV conversions was improved.
Release Notes: AMD64/EM64T 64-bit support was completed. Multi-threaded encoding support was introduced. SSE3/SSE4 optimizations were made. Faster and more precise MPEG intra quantization was enabled. A bug in packed pixel format colorspace conversion was fixed. A no-exec stack security patch was applied. A fix for bad resync marker length was made. Decoder robustness was improved for broken streams containing B-frames. A fix for potential out-of-bound access to MV bits table was made. An SSIM quality-metric plugin was added.
Release Notes: This release fixes a potential vulnerability in mbcoding.c as reported in the Secunia advisory SA25711.
Release Notes: A bug with frame-drop in combination with packed B-frames was fixed. Non-aligned bitstream buffers were fixed. Several fixes for IA64, for potential crashes on EM64T, and for a segfault in the VFW frontend were made.
Release Notes: Improved low bitrate quality and VBV support. Rate-Distortion mode decision for bvops. New post-processing functions: brightness and deringing. New ports: PowerPC and AMD-64. Various decoder and encoder speedups. A few bugs have been squashed.
Release Notes: This beta release has an API that is very close to the 1.0.x branch, with only few changes. The library can still be used with client applications based on 1.0.x.
Release Notes: This release fixed very minor bugs and is source and binary compatible with the previous version. Trellis optimization overflows for quant smaller than or equal to 2 were fixed, streams that are too short are no longer read, preventing the reading of useless stream garbage, and 64-bit crashes that occurred due to addressing assuming 32-bit integers were fixed. Two diamond search bugs were fixed, one of which was causing searches in wrong directions, the other causing an early exit.
Release Notes: Several bugs have been fixed, including a memory leak in the VFW frontend and a thread safety problem in the xvidcore library.
Release Notes: DC misprediction caused by missing value clipping, bugs triggered by 1fps sequences in the decoder, a bug in trellis that was causing block skipping in later stages, and an ME bug that could cause suboptimal results for bframes have been fixed. An error in bit rate calculation when given the bit rate and size (2.4%) has been fixed. ICM compatibility has been added for office suites (OpenOffice.org, MS Office, etc.). More known audio file types have been added.
