RTSP URI Format
A Uniform Resource Identifiers (URI) is a compact string of characters used to identify or name
a resource on the Internet. The main purpose of this identification is to enable interaction with
representations of the resource over a network, typically the World Wide Web, using specific
protocols. A URI is defined in schemes defining a specific syntax and associated protocols.
General Structure
The URI is built of stream specifications. Each stream specification contains a keyword that
identifies the type of the stream (by which stream handlers are registered in the application), and
optionally a list of parameters that modify the default behavior of the stream.
rtsp://ip.address/keyword[?param1[=value1][&param2[=value2]…].]/keyword…
A more detailed example of the RTSP URI format is as follows:
rtsp://ip_address/?multicast{&param1{=val1}{&param2{=val2}...}}/video_media{?param1{=val1}
{&param2{=val2}...}}/audio_media{?param1{=val1}{&param2{=val2}...}}
Note: Curly braces indicate optional parameters
Where ip_address is the address of the board.
multicast section is optional if the user wants multicast streaming (otherwise streaming is regular
unicast).
The user can specify a stream of
video_media
and/or a stream of
audio_media
.
video_media can be “mjpeg”, or “h264”.
audio_media can be “pcma”, “pcmu” for audio. PCMA and PCMU are G.711 A-Law and μ-Law,
respectively.
Param, val: A list of parameters separated by ‘&’. Some parameters appear on their own, others
have a value. In that case they appear as param=value. Except as noted, any parameter not
specified in the URI takes its default value from the Web page settings.
The default values given in the following tables are the initial factory settings. With the exception
of “cam” and “mic”, they may all be changed in the Web menu.
