SubscribeStreamImage

Subcriber Image Capture

R5Stream.getStreamImage allows the user to capture a screenshot of the stream at any time.

Example Code

• BaseTest.swift
• SubscribeStreamImageTest.swift

Running the example

Begin by publishing to stream1 from a second device. stream1 is the default stream1 name that is used by this example. Select the SubscribeStreamImageTest option to open a subscriber view.

Touch the screen at any time while streaming to popup a temporary overlay containing the UIImage that is returned from the Red5 Pro SDK.

Using getStreamImage

R5Stream.getStreamImage returns a UIImage containing a screenshot of the current stream. The image dimensions match the incoming stream dimensions, and contain RGB data. Once streaming, simply call:

uiv!.image = self.publishStream?.getStreamImage();

SubscribeStreamImageTest.swift #56

The UIImage can be saved to disk, displayed with a UIImageView, or processed in any way that is needed.
