It's not always time-dependent. Standalone image processing, for example, is not. My understanding is that the different abstraction layers such as data structures (pixel, sample, audio/video frame), algorithms (conversion, resampling, scaling, etc) and higher level tools (timing, pipeline/graph, multithreading, I/O) should be as decoupled as possible. > Should we build a library that does more than sound? I think the pipeline/graph framework is orthogonal to audio or whatever media processing, although can be employed for these tasks as well. Think of a generic framework like in TBB. That, however, does not immediately help audio/video processing as the sample/pixel/frame and DSP layers are still missing and, IMHO, would be a very useful addition even without the graph framework. -- You received this message because you are subscribed to the Google Groups "ISO C++ Standard - Future Proposals" group.
