x264 What is x264: x264 is a free library for encoding H264/AVC video streams. The code is written by Laurent Aimar, Eric Petit(OS X), Min Chen (vfw/nasm), Justin Clay(vfw), Måns Rullgård and Loren Merritt from scratch. It is released under the terms of the GPL license.

Properly dealing with adaptive interlacing in all cases takes lots of code. x264 doesn't support interlacing.There are a few other features not supported..."

It is designed for easy use & as a non-restrictive development playback platform for 3rd parties to license.     TCPMP for PalmOS 可以说是PlamOS 上面最好的媒体播放器，支持MPEG1、MPEG4、MP3、MP4、M4A、MKV、OGG、MJPEG、ADPCM、ALaw、MuLaw、MPC、3GP、WMV、AC3 音频、Sony HHE GE2D、Zodiac ATI 2D 加速、FFmpeg 媒体库等等。 http://corecodec.org/projects/tcpmp FFMPEG-PHP http://ffmpeg-php.sourceforge.net/index.php     ffmpeg-php is an extension for PHP that adds an easy to use, object-oriented API for accessing and retrieving information from video and audio files. It has methods for returning frames from movie files as images that can be manipulated using PHP's image functions. This works well for automatically creating thumbnail images from movies. ffmpeg-php is also useful for reporting the duration and bitrate of audio files (mp3, wma...). ffmpeg-php can access many of the video formats supported by ffmpeg (mov, avi, mpg, wmv...) FFMPEG http://ffmpeg.mplayerhq.hu/index.html     FFmpeg is a complete solution to record, convert and stream audio and video. It includes libavcodec, the leading audio/video codec library. FFmpeg is developed under Linux, but it can compiled under most operating systems, including Windows.     The project is made of several components: ffmpeg is a command line tool to convert one video file format to another. It also supports grabbing and encoding in real time from a TV card. ffserver is an HTTP (RTSP is being developped) multimedia streaming server for live broadcasts. Time shifting of live broadcast is also supported. ffplay is a simple media player based on SDL and on the FFmpeg libraries. libavcodec is a library containing all the FFmpeg audio/video encoders and decoders. Most codecs were developped from scratch to ensure best performances and high code reusability. libavformat is a library containing parsers and generators for all common audio/video formats. GStreamer http://gstreamer.freedesktop.org/     GStreamer is a library that allows the construction of graphs of media-handling components, ranging from simple Ogg/Vorbis playback to complex audio (mixing) and video (non-linear editing) processing.     Applications can take advantage of advances in codec and filter technology transparently. Developers can add new codecs and filters by writing a simple plugin with a clean, generic interface.     GStreamer is released under the LGPL. pthreads-win32 pthreads-win32是windows下的pthread库，和linux下一模一样，很不错的 windows下的pthread库：pthreads-win32 官方网站是：http://sourceware.org/pthreads-win32/ 官方FTP是：ftp://sources.redhat.com/pub/pthreads-win32/
