encode For specifying compression format. For example, specify as encode=mpeg4 to get MPEG-4.
ptz_info To add pan/tilt/zoom information before MPEG-4 VOP data. Specify on or off. Even if ptz_info=off,
pan/tilt/zoom information is stored in JPEG comment segemnt.
2.3. Response
When API is successfully received
VN-V686 will return 200 OK. The x-vnv686_response line indicates actual parameter.
Example
HTTP/1.1 200 OK<CRLF>
Connection: close<CRLF>
Content-Type: video/mp4v-es<CRLF>
Date: Tue, 02 Oct 2007 07:33:12 GMT<CRLF>
Server: JVC VN-V686 Network Camera<CRLF>
x-vnv686_response:
encode=mpeg4&framerate=30&framesize=vga&ptz_info=off<CRLF><CRLF>
MPEG-4 framerate can be changed by Web page or API. When MPEG-4 framerate is changed, the framerate of
current stream is changed also.
2.4. Restrictions
Access restriction
VN-V686 has access restriction feature that enables to deny access from a specific IP address. If MPEG-4 is
requested from the IP address of access restriction, VN-V686 disconnects the TCP connection after API is sent.
Restriction by maximum bitrate of VN-V686
The maximum bitrate of VN-V686 is about 20 Mbps.
Number of clients
The maximum number of clients that can get MPEG-4 stream depends on encode settings and JPEG clients. Refer the
instruction manual for detailed information.
2. MPEG-4 Stream Format Sent Out by VN-V686
MPEG-4 stream from VN-V686 is MPEG-4 Part 2(ISO/IEC 14496-2) compliant, level 3 of simple profile. It is a
sequence of I-VOPs, or I-VOPs and P-VOPs.
I-VOP: Intra frame compressed data
