upnp

问题 I'm writing a UPnP AV/DLNA DMS which needs to send and receive SSDP messages. In response to some M-SEARCH packets I need to send a reply with the URL of a resource (in this case a HTTP server), which I've chosen to bind to INADDR_ANY ( 0.0.0.0 ). Of course this address is meaningless to the sender of the M-SEARCH packet: The address of the interface on which the M-SEARCH was received is most appropriate. How can I determine the appropriate address to send in the reply packet? Some ideas I've

问题 Am I right in thinking that if I'm DLNA 1.5 compliant, I've implemented UPnP AV? What does DLNA get me besides specifying minimum format requirements? Isn't DLNA built on top of UPnP? I know for sure that DLNA device discovery is completely based on SSDP (UPnP's device discovery protocol). Does DLNA add something in the content discovery or content delivery specification? For example, Boxee and XBMC both support UPnP - don't they work with all DLNA devices? 回答1: Looking at the DLNA and UPnP

问题 I'm new at SSDP/UPNP/Sockets and all that jazz. I'm playing around with it a bit and I just want to see what a generic SSDP search on my network will bring up. Using this SSDP Sniffer app, I get a lot of results so I'm attempting to recreate this. I'm using the following code, which I've found various versions of, but all the tweaking I do doesn't appear to bring back any results. I pretty much at a loss here and would appreciate any guidance. thanks! private const string SSDP_IP = "239.255

问题 Please help! I am trying to build a parser to parse SSDP messages as defined in the UPnP protocol. (see "Discovery" section) Basically it's a header of HTTP OK, followed by name: value pairs, and finally a blank line. After roughly 5000 combinations, this is the one that I most think "should" work: * class SsdpParser() extends JavaTokenParsers { def fulldoc: Parser[SsdpMessage] = header ~ nameValuePairs <~ "\r\n" ^^ { case header ~ values => SsdpMessage(header, values) } def nameValuePairs

问题 I created a small program to test UPnP Multicast (Visual C# 2010 Express, running on Windows 7 Professional 64 Bit). I can receive the UPnP NOTIFY Messages from UPnP Devices in my Network. But when i send the M-SEARCH Message, i get no Answers. I have tested the same code on a iOS environment (Monotouch for iOS, running on a iPhone simulator on a Mac). There it runs fine and i get all the search responses from my UPnP devices. I can also see the M-SEARCH message from my windows program. It

问题 I am new to DLNA And UPNP Technology. I am building one app to cast videos(specially Live Streaming formats: .M3U8 & .RTMP) and audios to smartTVs(Samsung, LG, Sony, Panasonic, Toshiba, Sharp and Philips). I searched a lot about DLNA/UPNP and also found some helpful resources but confused at some points. Can we cast Live Streaming Videos? How to test app with all brand smart TVs as I don't have any smart TV. 3). Which library is better to use in swift? And also suggest me Good tutorials and

问题 I'm attempting to interact with a UPnP printer on my network. I can discover the printer, get the available services on it, and even get the list of actions available for a service. However, this is where I'm stuck. For example, there is an action GetPrinterAttributes and I know I need to create a http POST to send an envelop requesting the action, but I do no know what that looks like. I'm hoping someone can help point me to documentation or anything to get me going again. Based on other

问题 I have an embedded system that gets UTF-8 encoded data to display via UPNP. The display device has the ability to display characters. I need a way to convert the UTF-8 data I recieve via UPNP to unicode. The display is on a PIC, and it is sent data via a UPNP bridge running linux. Is there a simple way to do the conversion before I send it to the display board in linux? 回答1: If you have a real operating system and hosted C environment at your disposal, the best approach would be to simply

问题 I'm trying to communicate with dlna compliant devices using a C#.net application, using the UPnP protocol. I'm using the default Visual studio UPnP library("UPnP 1.0 type library (control point)"). I list all rendering devices using UPNPDeviceFinder.FindByType. All works fine... Now I get the AVTransport service using the function: public UPnPService GetAVTransport(UPnPDevice mediaDevice) { foreach (UPnPService service in mediaDevice.Services) { Debug.Print(service.ServiceTypeIdentifier); if

问题 I am having a small problem when using the upnpx library. I have downloaded the library and opened the upnpdemo workspace. I created in the same workspace a new project to try to create a simple app with this library. I set the parameters like a demo project, but XCode returns 21 errors: Apple Mach-O Linker Error Undefined symbols for architecture i386: "std::string::find(char const*, unsigned long) const", referenced from: 回答1: In your new project's build settings, set the C++ Language
