RaspiMJPEG Error: Could not open main PIPE

{2017/07/07 21:39:02} RaspiMJPEG Version 5.8.03
{2017/07/07 21:39:02} recommended video buffer size 65536
{2017/07/07 21:39:02} h264 size set to 131072
{2017/07/07 21:39:02} recommended video buffers 1
{2017/07/07 21:39:02} h264 buffers set to recommended 1
{2017/07/07 21:39:02} Error: Could not open main PIPE

RaspiMJPEG fails in opening pipes. This error can occur if the designated pipes do NOT exist or the permission to the pipes is NOT appropriate. 

1. Check what pipes are required in /etc/raspimjpeg
2. Create pipes

For instance,
$ sudo mknod /var/www/.../FIFO p
$ sudo chmod 666 /var/www/.../FIFO
