roRtspStream

This is a simple media-streaming object that is passed to the roVideoPlayer.PlayFile() method. Use this object to play UDP, RTP, HLS, and HTTP streams. See the Video Streaming and IP Camera FAQs for more details. The JavaScript equivalent is to use <video> elements.

Object Creation: To play a stream, instantiate an roRtspStream object with a URL as its argument. Then pass it to the PlayFile() method as shown in the following example:

v = createobject("rovideoplayer")
r = createobject("rortspstream", "http://172.30.1.37/alldigital/1080p/playlist.m3u8")
v.playfile({rtsp:r})

The key in the passed associative array will always be "rtsp", no matter which streaming protocol is used.

ifRtspStream

GetUrl() As String

Retrieves the currently configured URL.

AddHeader(header As String, text As String)

Adds the specified header and header text to the streaming request. The ":" after the header and the "\r\n" after the header text are supplied automatically by the method. Headers only take effect when a stream is played; you cannot add more headers when a stream is playing (though these headers will be applied if the stream is played again).

ClearHeaders()

Removes headers that have been added using the AddHeader() method.

ifMessagePort

SetPort(port As roMessagePort)

Posts event messages to the attached message port. The event messages are of the type roRtspStreamEvent and will implement the ifInt interface.

ifUserData

SetUserData(user_data As Object)

Sets the user data that will be returned when events are raised.

GetUserData() As Object

Returns the user data that has previously been set via SetUserData(). It will return Invalid if no data has been set.
