2. JVC Protocol: JPEG Streaming
2.1. Basic Procedures
1) The client establishes a TCP connection to port number 80.
2) The client sends out API.
Example
to get JPEG stream encoded by first channel of the camera
GET /api/video?encode=jpeg(1)&framerate=5&server_push=on HTTP/1.1<CRLF>
Host: 192.168.0.2<CRLF><CRLF>
Note <CRLF> denotes the line feed code (
0x0D, 0x0A
).
3) The camera returns HTTP response and JPEG stream.
JPEG files in boundary structure will be sent out continuously after HTTP response. Each Content-Length is the
size of each JPEG data. Using the size, reading the whole data of each JPEG is possible. HTTP Response and
JPEG data sent out by the camera are as follows.
HTTP Response
JPEG (No. 1)
