<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">Nginx-rtmp-module is an open-source Nginx module implementing support for RTMP, HLS and MPEG-DASH streaming protocols. The module makes use of Nginx's asynchronous event model providing high performance. RTMP is great for serving live content. When RTMP is paired with FFmpeg, streams can be converted into various qualities.</span></span></div>

After you've added the above, you can customize settings such a video bitrate, audio bitrate and resolution. These changes will only be applied to the lower quality stream. To add more qualities, copy and paste the exec ffmpeg line and change the settings. You'll also need to create a new application. You can do this by copying and pasting the live360 example that has been included. Don't forget to update the exec ffmpeg line with the address of the new application. You can do this by changing the final RTMP address in the exec ffmpeg line.</div>
