Comparison with EGL

When using EGLStreams, there is never any need to explicitly deal with synchronization objects. They are present in the NVIDIA EGL implementation, but require no action on the application's part. This is possible because the producer and consumer rendering libraries connect directly to an EGLStream and are able to coordinate synchronization setup themselves through the stream without the user being aware of it. In the NvSciStream model, the rendering libraries do not access the stream. Resources must be transferred between them and the stream. Therefore, these additional steps are required to initialize synchronization.
