When using library with .net 4.5.1 I sometimes get same device multiple times,

var devices = await new Ssdp().SearchUPnPDevices("SsdpSearch:all");

Hi @kakone !

While i'm searching my media render devices I found my Philips hue gate!! 😄 😄

I've found an extremely weird issue; it's reproducible when you compile UWP app with .NET Native tool chain only and (probably) with Hisense TV sets (without native tool chain everything works fine!). Also, it's happened for videos (mp4 etc.) only, image/jpeg content is working fine. It's a really strange!

Here are packets captures from WireShark (in readable text form, binary attachment below):

"bad" packet (getting "Internal Server Error"):

"good" packet (correct response, playback is good - this one was made without compiling with native tool chain)

Instead of/in addition to .NET Portable.

a great job, but I have trouble testing it.

I created a solution (UWP 10) with reference to your project (Figure 1)
when I start and try to test it (I added a try catch) the app goes wrong (Figure 2)

the method or operation is not implemented

Hi Stéphane, sorry for disturbing you again but maybe you can provide some suggestions.

My current TV set, Hisense Smart TV, has one weird "feature" (previous TV set, Panasonic Viera, accidentally broken, worked fine): between two PlayAsync I need to call StopAsync (otherwise I'm getting exception) but TV switches quickly from DLNA renderer screen to the current input. This behavior is kinda annoying, especially for the pics slideshow.

I tried to add additional commands to AVTransportControlPoint: SetNextUriAsync, NextAsync and PreviousAsync but looks like SetNextUriAsync is not working (see attached sources), I'm getting an exception.

Stéphane, what you can recommend for the seamless slideshow experience?

AVTransport.zip

Unable to get MD5 checksum for the key file "key.pfx"Could not find file....

even with your suggestion :( I recreated UWP class library with your sources but Ssdp.cs does not compile, UWP has different socket.SendToAsync and socket.ReceiveAsync implementations.

Could you please help with UWP code?

Thanks a lot!

I'm really sorry, Stéphane, but I don't have your email to ask a few more questions so I'm using github "Issues" :) BTW, you may treat this as a feature request... Or you may simple junk it or close this issue (I do understand).

So, my first question is: is it possible to add custom "banner" for AVTransportControlPoint class, to be displayed on the DLNA renderer (i.e. TV)? Theoretically, AFAIK, it's possible; casting by using Windows.Media.Casting API do have a custom banner - instead of the raw file name TV got custom string (like "Media from <your_app_name>"). Will be good to add this feature to the project!

My second question isn't related to your project: could you please recommend me some UWP HTTP server implementation, good enough to work as DLNA media source server (i.e. HTTP 1.1 server which supports sending large files with additional processing of HTTP headers - in case of seeking/scrubbing in mp4 video)? I tried a few github hosted projects but all of 'em are ... can't blame open sources devs but these servers are too simple and have minimal set of functionality (yes, they are good to send short strings with JSON or XML but definitely not ready for sending large mp4's).
