BergWave

Description:

BergWave is a wavelet based video de/en-coding solution.

The BergWave package currently consists of three parts :

- libbw: the main video de-/encoding library
- test: a simple example programm
- vfw: video for windows interface

BergWave is working in yv12 colorspace. Color conversion functions where XviD taken from the XviD project, a open source MPEG 4 video codec (www.xvid.org).
At the moment BergWave doesn’t support delta frames, but that’s on the doto list. To compress the yv12 image BergWave uses 5,3 wavelet transform with run length encoding.

ffvfw 20031028

Description:

Video for Windows and DirectShow codec based on VFW code from XviD project and using libavcodec library from ffmpeg project for compression. Few other compression libraries are supported too.
Latest unofficial versions also supports other compressions like WMW, MPEG1, MPEG2.

various compression methods: MPEG 4 compatible (Xvid, DivX 4, DivX 5) using libavcodec or XviD; Divx 3 compatible, MSMPEG4v2, MSMPEG4v1; WMV1/7, WMV2/8; H263, H263+; HuffYUV in YV12 colorspace; MJPEG; MPEG 1; Theora (not for regular use, format isn’t stabilized yet); MPEG 2 by using mpeg2enc code from MJPEGtools project; all Windows Media Video 9 supported encoders with output to asf/wmv file or AVI
- all common encoding modes: constant bitrate, fixed quantizer, fixed quality, two pass encoding (depends on compressor features)
- for libavcodec and XviD detailed selection of motion estimation method
- minimum and maximum I frames interval
- minimum and maximum quantizer selection, quantizer type and trellis quantization selection for libavcodec
- adaptive quantization (aka. masking) for libavcodec and XviD, single coefficient elimination
- selectable compression of starting and ending credits
- two curve compression algorithms for second pass of two pass encoding – thanks to XviD developers
- second pass simulation: although not very precise, still helpful for tweaking advanced curve compression parameters
- ability to use libavcodec internal two pass code
- image preprocessing with ffdshow image filters (latest ffdshow version must be installed)
- graph during encoding: if your encoding program doesn’t provide one
- B frames support: from one to eight consecutive B frames
- support for MPEG 4 quarterpel and GMC
- selectable interlaced encoding
- decompression.

CoreVorbis Decoder

Description:

CoreVorbis is a DirectShow-Decoder for the Vorbis audio codec. It allows you to play files containing Vorbis-audio in many players, for example Windows Media Player, Media Player Classic or The Core Media Player.

Vorbis is a fully open, non-proprietary, patent-and-royalty-free, general-purpose compressed audio format for mid to high quality (6kHz-96kHz, 16+ bit, polyphonic) audio and music at fixed and variable bitrates from 2 to 256 kbps/channel. This places Vorbis in the same competitive class as audio representations such as MPEG-4 (AAC), and similar to, but higher performance than MPEG-1/2 audio layer 3 (MP3), TwinVQ (VQF), WMA and PAC.

Changes from CoreVorbis 1.0 to CoreVorbis 1.1

• Notes:
- Better mediatype change handling.
- Compiled with last version of the vorbis library.
• Changes:
- Better mediatype change handling.
- Compiled with last version of the vorbis library.
