Hi Vincent, It's an interesting capability to have on b2g. As a general comment, it might be better to minimize the modification to gonk(android) part as minimum as possible. Especially around stagefright. android's media framework tend to have platform vendor's customization.

Generally speaking, Miracast can project/mirror one screen (e.g. our cell phone) to another (e.g. TV). You can find a cool demo and a brief introduction in the following link: https://www.youtube.com/watch?v=NA3Opudj4VU&noredirect=1 Miracast, or "Wifi Display", is based on two important technologies: Wifi Direct and RTSP. With "Wifi Direct", two devices can connect to each other without an AP; RTSP is the protocol used to stream out the frames shown on our screen. We've already created a meta bug 925615 to keep track of the development, which contains several sub-tasks, such as Bug 811635 - B2G Wifi: Support Wifi Direct Bug 945569 - Support Wifi Display device discovery and group formation Bug 946110 - [B2G][WFD] Porting libstagefright_wfd to Necko Bug 947063 - Secreview: Support Wifi Display Bug 949901 - [B2G][WFD] Implementing WifiDisplayManager and its DOM counter part and the proposed design diagram: https://bug925615.bugzilla.mozilla.org/attachment.cgi?id=8347062 The biggest design decision we haven't made is what process RTSP server should reside. Does anyone have any suggestion on this as well as the overall design? Thanks :) Many Thanks, Vincent Chang, Software Engineer of Mozilla Taiwan _______________________________________________ dev-b2g mailing list [email protected] https://lists.mozilla.org/listinfo/dev-b2g _______________________________________________ dev-media mailing list [email protected] https://lists.mozilla.org/listinfo/dev-media
