x264 Video Encoder rev. 2208 x86/x64
27.07.2012 19:17

x264 - H.264(MPEG-4 AVC) кодировщик (x86/x64) - это свободная библиотека программных компонентов для кодирования видеопотоков H.264/MPEG-4 AVC.

x264 - H.264(MPEG-4 AVC) Encoder (x86/x64) is a free library for encoding H.264/MPEG-4 AVC video streams.

 

Изменения / Changes:

  • Fix crash with --fps 0. Fix some integer overflows and check input parameters better. Also fix incorrect type specifiers for demuxer info printing.;
  • x86inc: import patches from libav. Allow manual invocation of WIN64_SPILL_XMM even under INIT_MMX. SSE version of mova is movaps rather than movdqa. YMM version of movnta. Add mp size for named arguments. Fix DEFINE_ARGS when used outside of a cglobal. Define a few more cpuflags. 3-argument wrappers for a few more instructions.;
  • Cap ratecontrol predictor parameters. Limits VBV mispredictions after long periods of relatively constant video.;
  • Print elapsed time in encoding progress indicator;
  • Support changing resolutions between passes with macroblock-tree. Implement a basic separable bilinear filter to rescale the quantizer offsets. Structure inspired by swscale, but floating-point instead of fixed-point. Not as optimized as it could be, but it's quite fast already.  Example compression penalties on a 720p video game recording:
        First pass with 720p and second as 480p: ~-1.5% (vs. same res)
        First pass with 480p and second as 720p: ~-3% (vs. same res);
  • Try 8x8 transform analysis even when sub8x8 partitions are present. Turn off the sub8x8 partitions, try it, and turn them back on if it didn't help. Small compression improvement with p4x4 on (~0.1-0.5%). Also update related comments.;
  • Faster predictor checking with subme<3. Fix a typo that made an early-skip less effective. Avoid a relatively unpredictable branch. Slightly changed output due to the typo-fix. ~50 cycles faster on Core i7.;
  • Revert r2204. People don't seem to like this so I'm just going to get rid of it.

x262 mpeg-2 Video Encoder rev. 2433 x86/x64 (Experimental version!)
27.07.2012 19:02

x262, Mpeg-2 видео кодировщик, работающий на базе видео энкодера x264.

x262, an mpeg-2 encoder building on the best-in-class features of x264.

 

Изменения / Changes:

  •  
  • MPEG-2: Restrict colorspace to 4:2:0 or 4:2:2.
  • MPEG-2: Support Matroska output.
  • MPEG-2: Allow forcing a higher profile than strictly necessary.
  • MPEG-2: Change default logging. Print "x262" instead of "x264" so that MPEG-2/H.264 is more obvious.
  • MPEG-2: API improvements. Library users can simply call x264_param_default_preset_mpeg2() to setup MPEG-2 encoding. Other API functions will not overwrite any mandatory settings. Also modify the CLI so that the --mpeg2 and --no-mpeg2 options work however the binary is called
  • MPEG-2: Prefix level names.
  • MPEG-2: Change lookahead QP. 1 was chosen because its qscale is comparable to QP 12 for H.264. Improves PSNR/SSIM a tiny bit.
  • Merge remote-tracking branch 'x264/master';
  • Fix reading of uninitialised parameter when encoding from the CLI.;
  • MPEG-2: Update copyright;
  • MPEG-2: Initial interlaced encoding support. Uses VSAD to detect interlaced macroblocks. Currently limited to 4:2:0 only..

Media Player Classic, svn 114 (eng) (x86)
11.04.2011 02:29

Media Player Classic — свободно-распространяемый проигрыватель аудио- и видео-файлов для операционной системы Windows. Программа имеет интерфейс, аналогичный Windows Media Player версии 6.4, однако основан на совершенно другой кодовой базе и по функциональным возможностям значительно его превосходит.

 

Media Player Classic looks just like Windows Media Player 6.4, but has many additional features. It has a built in DVD player with real-time zoom, support for AVI subtitles, QuickTime and RealVideo support (requires QuickTime and/or Real Player); built-in MPEG2/SVCD/DVD codec 

 

Изменения/Changes:

  • update svn ignore list;
  • add the needed DirectX include files and ddraw.lib;
  • add the atl include files;
  • add VS2008 project/solution files (quickly updated from VS2005 files with the minimum needed changes to com, English, German, Hungarian, Polish, Russian, Spanish.
