Hi edwards.

I think you want to have ffmpeg that supporting rtmp input. Previously I had an experience with rtmpdump; piping it's output to the VLC; then VLC could play it. maybe ffmpeg also work as this. Also I am so excited to receive rtmp stream directly by ffmpeg. I'll follow this post. 

kind regards;

Hey Mortiz,

Thanks a lot for your help.

To be more specific, I had already compiled ffmpeg. I wanted to recompile
ffmpeg with rtmpdump support.

I apologize for my inexperience regarding ffmpeg. I have rtmpsump already
compiled and installed.

How should I clean up my librtmp installation?

Best Regards.
