Considering the domain of media codecs is a patent minefield, the API should be designed around never having access to the actual contents of the frames, only that they exist. More than likely, just "here's a file or URL, go play it", plus some time-sync API and some hints on what type of audio it is, so system can route it to the correct speaker (headphones? bluetooth? loudspeaker?). Plus the converse recording. IMHO, just like the 2D graphics proposal, I think this is ill-advised as content for the C++ Standard Library. -- Thiago Macieira - thiago (AT) macieira.info - thiago (AT) kde.org Software Architect - Intel Open Source Technology Center -- You received this message because you are subscribed to the Google Groups "ISO C++ Standard - Future Proposals" group.
