CMIOExtensionStream direction CMIOExtensionStreamDirectionSink

Question

_streamSinkIn = [[CMIOExtensionStream alloc] initWithLocalizedName:localizedName
streamID:streamInputID 
direction:CMIOExtensionStreamDirectionSink clockType:CMIOExtensionStreamClockTypeHostTime
source:self];

Attempting to publish a CMIOExtensionStream with the 'sink' direction (i.e. print-to-tape) as alluded to in Brad Ford's presentation. Any attempt to create such a stream yields and invalid argument exception and if you examine the header files all the init methods are described as returning stream instances that source data (ie camera publishers).

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Invalid argument'

Well, it's an example of setting up the sink stream. It doesn't do anything with it yet - I'm still working that part out.

@DrXibber and @Amallik and @MarkBessey I posted a full example of how to declare a source and sink streams, and how to feed the sink sample buffers from the main app.

Answer 5

@Idenoue , Thanks for sample code. Your code working fine . I have one query, can we do something like , when our App running at that time only its shows in Third party App like quicktime. When I close my App it Remove from device list of third party App.

We have to install/uninstall only one time.
