<div style="line-height:1.7;color:#000000;font-size:14px;font-family:Arial">Hi,<br><br>FFmpeg has its native rtmp plugin, and also can use rtmpdump instead if enable-librtmp is chosen when building ffmpeg.<br><br>I
have reviewed rtmp specification, where client and server can notify
its peer of audio/video information via metadata message, and of
audio/video codec via connect command.<br><br>For live-streamming
application, what is the common way to get audio/video information, such
as bit rate, audio channel number, sample rate, and frame rate? Are
there some ffmpeg functions to get those information?<br><br>Thanks!<br><br>Regards<br><br>Andrew</div><br><br><span title="neteasefooter"><p> </p></span>
