Contributor guide

Research direction
Investigate how javacv sets the packet duration when encoding audio for RTMP. Focus on the frame size and sample rate settings. Check if the output packet duration is determined by the encoder configuration or the input stream properties. Look for relevant FFmpeg options like 'frame size' or 'packet size' that might be exposed via javacv.
