Description: LibMPEG3 decodes several MPEG standards into uncompressed data suitable for editing and playback.
libmpeg3 currently decodes:
MPEG-2 video
MPEG-1 video
mp3 audio
mp2 audio
ac3 audio
MPEG-2 transport streams
MPEG-2 program streams
MPEG-1 program streams
IFO files
The video output can be in many different color models and frame sizes. The audio output can be in twos compliment or floating point. Frame accurate seeking, normally impossible in transport streams, is possible in libmpeg3 through the use of a table of contents. MPEG-2 video in YUV-422 colorspace is decodable. Digital TV broadcasts and DVD s can be edited using libmpeg3. Libmpeg3 takes what is normally a last mile distribution format and makes it editable.
Because of these and other features libmpeg3 is not intended for consumer applications but serves users who are interested in high quality editing and footage acquisition.

Description: MONOGRAM MPEG Audio Encoder 0.9-after a while there’s yet another new encoder available :). I have created an MPEG Layer 2 encoder based on the libavcodec (ffmpeg) source code. Unluckily the libavcodec encoder lacks a nice psychoacoustic model so I’m considering taking a look at the TwoLame library. Until then please do some testing and if you find any problem with the filter please do report it. This filter is released under the GNU LGPL license.

Description: 基于核密度估计的背景减法算法，拥有命令行界面的C++源代码。-kernel density estimation based background subtraction algorithm [1] with a command line interface. this algorithm is a somewhat improved version of [2].
the kmovingobjdetector class within the project is originally written by birant orten who has graciously allowed me to use his code. i just modified it to suit my purposes. so, if you use any material from this program you should refer both [1] and [2] apart from this web-page.
if you compile with __OPENCV__ flag, you ll be able to open avi files. without this flag, you will be able to open just ppm images. the usage.txt explains the input specifications.
