[f009801] | 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 can
|
---|
| 34 | also acquire from a live audio/video source. Designed to be intuitive, the
|
---|
| 35 | command-line interface (<command>ffmpeg</command>) tries to figure out all the
|
---|
| 36 | parameters, when possible. <application>FFmpeg</application> can also convert
|
---|
| 37 | from any sample rate to any other, and resize video on the fly with a high
|
---|
| 38 | quality polyphase filter. <application>FFmpeg</application> can use a
|
---|
| 39 | video4linux compatible video source and any Open Sound System audio
|
