avconv

avconv

In March 2011 some of the FFmpeg developers forked the project under the name "Libav".

Libav is a complete, cross-platform solution to record, convert and stream audio and video. It includes libavcodec - the leading audio/video codec library. One of the components of libav is avconv, a fast open source video and audio converter that can also grab from a live audio/video source. The command-line tool can also convert between arbitrary sample rates and resize video on the fly with a high quality polyphase filter.

Besides avconv, the libav-tools package offers the avplay multimedia player, the avserver streaming server, and the avprobe stream analyzer. The tooks support most existing file formats (AVI, MPEG, OGG, Matroska, ASF...) and encoding formats (MPEG, DivX, MPEG4, AC3, DV...).
