use a slider to look at certain frames when the video has been paused.
To create a server connection set the URL in the menu Preferences → Video Server. Video
server's URL has the format
http://ip-address:port-number/path
for example:
http://192.168.0.100:8080/video.cgi
The values depend on your video server. If you run the server in the same computer the address is
127.0.0.1. Only the basic authentication is supported, but it should be enough for the most IP
cameras.
Motion JPEG (M-JPEG) video is supported only. It is an informal name for a class of video formats
where each video frame is separately compressed as a JPEG image. Originally developed for
multimedia PC applications, where more advanced formats have displaced it, M-JPEG is now used
by many portable devices with video-capture capability, such as digital cameras. Many network-
enabled cameras provide M-JPEG streams that network clients can connect to.
HTTP streaming separates each image into individual HTTP replies on a specified marker. For M-
JPEG streams the JPEG data is sent to the client with a correct HTTP-header. The TCP
connection is not closed as long as the client wants to receive new frames and the server wants to
provide new frames.
There exist network-enabled M-JPEG cameras with a build-in HTTP server. Still it may be easier
and less expensive to have an USB web cam and server software running in the same computer.
VLC requires quite a lot CPU power. In general you have to find out the correct balance between
the picture quality (size, frames/sec) and the available CPU power. Appendix 5 has more
information about how to set up a video server.
Note: This is not a substitute for a real referee camera! A cheap static camera most probably
misses all the action details. Competitors are either too small or out of the picture. However, if
somebody takes care of the shooting this feature may have some entertainment value for the
audience and even referees may use it in less important tournaments that are not equipped with
real cameras.
