Description
An OS X and iOS app might use appsink to get resulting GstBuffers from a pipeline containing applemedia elements. Furthermore, it can wish to access (and retain) the underlying CMSampleBufferRef or CMPixelBufferRef, as they're needed:
-
to work with AVFoundation, Core Video and Core Image
-
for GL rendering done by app
How can we expose some of the applemedia stuff (e.g. coremediabuffer.h) as API?
