#771: RAOP streams are delayed ---------------------+------------------------------------------------------ Reporter: takkat | Owner: coling Type: defect | Status: new Milestone: | Component: module-raop-* Resolution: | Keywords: streaming airport express ---------------------+------------------------------------------------------
Comment(by coling): What it's labelled as really has no bearing whatsoever so feel free to call it what you want :) It is fully intensional that the silence is transmitted as without it, the APEX gets into a strange state and we can no longer reconnect to it without restarting PA. Even unloading and reloading the module isn't enough. It's all rather strange. So sending silence keeps the connection open and thus allows us to use it. Also the timing methodology is totally basic. It uses the buffer of the APEX itself to implement flow control where as we should really be feeding it data in real time. This is all complex stuff. There is also a much more accurate timing model available in the Airtunes v2 protocol, but it's not fully understood or reverse engineered yet. Some work has been done to get it working but the results still cause choppy sound at present. It's all work in progress, but as a lot of it is guess work it's a very slow process. If you'd like to help out with reverse engineering the protocol and such like, please let me know and I'll put you in touch with the right people. -- Ticket URL: <http://pulseaudio.org/ticket/771#comment:5> PulseAudio <http://pulseaudio.org/> The PulseAudio Sound Server _______________________________________________ pulseaudio-tickets mailing list pulseaudio-tickets@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-tickets
