<title>Introduction to FFmpeg</title>
|
|
|
|
<para><application>FFmpeg</application> is a solution to record, convert and
|
|
stream audio and video. It is a very fast video and audio converter and it can
|
|
also acquire from a live audio/video source. Designed to be intuitive, the
|
|
command-line interface (<command>ffmpeg</command>) tries to figure out all the
|
|
parameters, when possible. <application>FFmpeg</application> can also convert
|
|
from any sample rate to any other, and resize video on the fly with a high
|
|
quality polyphase filter. <application>FFmpeg</application> can use a
|
|
video4linux compatible video source and any Open Sound System audio
|
|
source.</para>
|
|
<para>The developers of this package do not make releases very often, so you
|
|
may wish to use a snapshot instead of this release. If you do that, you must
|
|
expect the acceptable <command>configure</command> switches, and the
|
|
dependencies, to change.</para>
