32 | <para><application>FFmpeg</application> is a solution to record, convert and

33 | stream audio and video. It is a very fast video and audio converter and it
|
---|
34 | can also acquire from a live audio/video source. Designed to be intuitive,
|
---|
35 | the command-line interface (<command>ffmpeg</command>) tries to figure out
|
---|
36 | all the parameters, when possible. <application>FFmpeg</application> can
|
---|
37 | also convert from any sample rate to any other, and resize video on the fly
|
---|
38 | with a high quality polyphase filter. <application>FFmpeg</application> can
|
---|
39 | use a video4linux compatible video source and any Open Sound System audio
|

187 | <application>FFmpeg</application> comes with code to compile decoders for

188 | almost every codec you could think of. The only reason to enable a specific

189 | codec (and make <application>FFmpeg</application> link to the prerequisite
|
---|
190 | shared library installed on your system) is to make ffmpeg compile an
|
---|
191 | <emphasis>encoder</emphasis> for that codec. Encoding video is a
|
---|
192 | specialist job. If that is what you want to do with
|
---|
193 | <command>ffmpeg</command>, study the output of <command>configure
|
---|
194 | --help</command>. Remember, the dependencies all install their own encoders
|
---|
195 | (that are often better than <application>FFmpeg</application>'s).
|
---|
196 | <application>FFmpeg</application> is an excellent collection of decoders.
|
---|
197 | If you just want to use <application>FFmpeg</application> to watch video or
|
---|
198 | listen to music (via other applications like
|
---|
199 | <application>Gstreamer</application>) then you will not benefit from

200 | linking it to another library.</para>
