Es gibt eine neue Version zum runterladen: ffmpeg-0.4.6
Die meisten Leute werden zwar sowieso immer den aktuellsten Snapshot holen oder aus CVS auschecken.. aber da die letzte Release über ein Jahr her ist muß dieses "Ereignis" schon etwas breitgetreten werden ;)

Hier die Projektinformation und die Änderungsliste von deren Homepage http://ffmpeg.sourceforge.net/
(Die Changelogs zwischen 0.4.6 und 0.4.7 sind anscheinend die Änderungen die bis heute im CVS eingepflegt sind, bis zum 0.4.7 Release dürften da noch einige dazukommen..)

Project Description
FFmpeg is a complete solution to record, convert and stream audio and video. It includes libavcodec, the leading audio/video codec library. FFmpeg is developped under Linux, but it can compile under most OSes, 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.
* 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.

FFmpeg is currently ALPHA software. Read the Online FFmpeg Documentation to learn about the supported formats, codecs and features. Read the Online FFserver Documentation to learn about ffserver usage.
