Hi,

FFmpeg has its native rtmp plugin, and also can use rtmpdump instead if enable-librtmp is chosen when building ffmpeg.

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.

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?

Thanks!

Regards

Andrew
