The current library targets Google's Default Media Receiver (message format and available operations).

However it would be nice if additional apps with their own protocol could be supported.

My idea would be something like this:

• Allow the ChromeCastClient client to use different controller implementations
• Register controller implementations along with their respective AppId
• Let ChromeCastClient automatically load the right controller for the current app

@Tapanila what do you think?

Also have a look at home-assistant-libs/pychromecast#101 (here I implemented a controller for DS Audio)

I'm having difficulty following the logic in ReceiverChannel.

• Why is await ConnectToApplication(Client.ChromecastApplicationId); called upon every ChromecastStatusResponse?
• Is it possible to have one ChromecastClient.ChromecastApplication(Id) that is updated upon receiving a ChromecastStatusResponse instead of manually setting it after launching an app? That way the currrent application id would always be filled with an up-to-date value.
• The need for two similar variables (Client.ChromecastApplicationId vs ChromecastClient.RunningApplication.AppId) confuses me

It would be nice if you would create feature branches and merge them to the dev branch, so that it is clear what is being worked on and so that each branch has a focus.

I have a question, how can I put the title movie in the metadata object, but i dont have the mediatype numbers

GENERIC
Generic template suitable for most media types. Used by chrome.cast.media.GenericMediaMetadata.
MOVIE
A full length movie. Used by chrome.cast.media.MovieMediaMetadata.
TV_SHOW
An episode of a TV series. Used by chrome.cast.media.TvShowMediaMetadata.
MUSIC_TRACK
A music track. Used by chrome.cast.media.MusicTrackMediaMetadata.
PHOTO
Photo. Used by chrome.cast.media.PhotoMediaMetadata.

the MovieMetadata object need a int, do you know the numbers in int?

Hey,

first big thx for this SDK it works nice. I hope it´s just my bad, cause i can´t connect to the chromecast.

I have a listbox with all Chromecast and this works well:

` private async void getChromecasts()
{
DeviceLocator deviceLocator = new DeviceLocator();
var cancellationTokenSource = new CancellationTokenSource();
cancellationTokenSource.CancelAfter(5000);
chromecasts = await deviceLocator.LocateDevicesAsync(cancellationTokenSource.Token);

        if(chromecasts.Count > 0)
        {
            foreach (Chromecast chromcast in chromecasts)
            {
                chromecastListBox.Items.Add(new ListBoxItem { Content = chromcast.FriendlyName, Tag = chromcast.DeviceUri });
            }
        }
        else
        {
            chromecastListBox.Items.Add(new ListBoxItem() { IsEnabled = false, Name = "noDevice", Content = "Keine Geräte gefunden" });
        }
        chromecastListBox.Items.Remove(search);
    }`

After that i can push the button to connect to the chromecast:

private void ConnectChromecast(object sender, RoutedEventArgs e) { ListBoxItem selectedChromecast = (ListBoxItem)chromecastListBox.SelectedItem; Testo.Text = selectedChromecast.Tag.ToString(); client.ConnectChromecast(chromecasts.Last().DeviceUri); }

I´ve also tried to set the DeviceUri manuell, but no way. Pls help me ;)

There is 3 different errors:

• https://developers.google.com/cast/docs/reference/messages#LoadFailed
• https://developers.google.com/cast/docs/reference/messages#LoadCancelled
• https://developers.google.com/cast/docs/reference/messages#InvalidRequest

Currently it builds Portable, .net45 and Universal into same folder and same name. This causes multiple problems and should be fixed.

• Check discovering chromecast

.

• Check discovering chromecast
• Check connecting to chromecast

This is because of SSL error on socket (Chromecast uses self signed certificates)

My uwp app crash when i try connect to chromecast.
I select device and try to connect then ( Uri and friendlyName is correct).
Error message : (CoreCLR: CoreCLR_UWP_Domain) : Chargé 'Anonymously Hosted DynamicMethods Assembly'.

thanks
PS, sorry for my english :(

For some reason I get a nullReferenceException when running the Simple app and sending a message (by changing the volume or clicking play/pause).

Reproduction:

• run a song in DS Audio on Chromecast
• run the SharpCaster.Simple app
• click in the volume slider or click play/pause

Symptoms:

• Volume slider is zero
• Volume updates are not received
• NullReferenceException: _socket is null in ChromecastSocketService.cs (in SharpCaster.UniversalWindows) - this is on line 54 in Write(byte[] bytes)

If application is already open instead of creating a new session of the application join it.

I receive this error when calling

_controller = await ChromecastService.ChromeCastClient.LaunchSharpCaster();

How do I fix this?

Two issues:

• When I reference the nuget package (0.1.5) from a blank UWP app then the protobuf-net library is not copied or referenced. Because of that I couldn't build my app with only the nuget package.
• Besides that I think it is not a good practice to put dll's in git. Is there maybe a Nuget version of the protobuf library available?

Google is working on one but that one seems to only support the proto3 version. Protobuf-net is also a nuget package but it seems there is some issue with the chosen target framework.

MusicTrackMediaMetadata does not display (album)artist

VB.NET:
metadata = New MusicTrackMediaMetadata() With { .albumArtist = artist, .artist = artist, .songName = song, .title = song }

Both "artist" and "song" have a value, the song is getting displayed on my screen correctly but the artist isn't.

I'm currently looking for an idea/suggestion for an app that would be leveraging the SharpCaster library

There is an issue to choose right network when there is multiple virtual network cards.

How to get current video on chromecast, title and poster of the video, cast is started by other app!?

Hi, can sharpcaster supporting caption or subtitles? I cant find MediaTracks option just CustomData,

Im a C# .net develop and xamarin too, im looking to cast witth captions or subtitles, i see that you using json to send to chromecast messages, should be good send the subtitle url there too, i have been using Google Services Cast but i dont like it, I like your develop to using in xamarin, but i need captions too. thanks for your work, can you tell me where or a suggestion to add subtitles to the sharpcaster?

I plan to start hosting a build agent with access to chromecast. That way we can always run automated test suite to make sure all the features keep working.

Features that should be tested:

• Connecting to a chromecast
• Launching application
• Rejoining existing application session
• Closing application
• Load media
• Seek
• Play/Pause
• Stop
• Verify metadata after load media
• Playback working (Check that playback starts after load media)
• Error handling (Need way to produce them and then make sure we catch them)

Make it easier to consume this library by creating a nuget package definition and use appvoyer to publish it.

Hey!
I'm trying to extend the MediaPlayer in a Windows 10 UWP App with SharpCaster to a Chromecast.

I have built a custom receiver app, that communicates via a channel with my app. On Android, this works perfectly but I can't find how to open app channels with SharpCaster, Creating a channel with the ChromecastChannel(client, "NS") does not work for me... My code:

chromecastClient.ApplicationStarted += (sender, application) =>
{
     var ch = new ChromecastChannel("*myappchannel*");
     ch.MessageReceived += (o, args) =>
     {
          Debugger.Break(); //Never triggered
     };
     var msg = new CastMessage { PayloadUtf8 = "{\"type\": \"MOVIE\", \"url\": \"myurl\"}" };
     await ch.Write(msg);
};

Sometimes the chromecast sends closed to tell the client to disconnect.

• Document creating new Controller
• Document creating new Channel
• Document all existing Controllers and Channels
• Document all LoadMedia parameters (example metadata, duration, streamtype and etc)

I installed the latest SharpCaster nuget package on a Windows 10 IOT background task project.
On ChromecastService.Current.StartLocatingDevices I get the following error:

Could not load file or assembly 'Rssdp.Portable, Version=2.0.0.1, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

The Rssdp.Portable.dll which is distributed in Rssdp-sharpcaster is version 1.0.0.12

Hi,

I stumbled upon your great project while researching options on supporting chromecast in windows apps.

A suggestion for future work would be to use already existing portable abstractions of UDP and TCP sockets (e.g. https://github.com/rdavisau/sockets-for-pcl which i've bee successfully working with)

I'm looking forward to future features.

Greetings

There has been few requests to cast a webpage.
This would probably need to build custom receiver which you can control to open web page

With Android & Chromecast its possible to play .mp4 files. But if i try to load a mp4 file nothing happens.

client.Connected += async delegate { await client.LaunchApplication("B3419EF5"); }; client.ApplicationStarted += async delegate { await client.LoadMedia("http://www.w3schools.com/html/mov_bbb.mp4"); }; client.ConnectChromecast(new Uri(selectedChromecast.Tag.ToString()));

I still just see "SharpCaster demo receiver" :/

I hope you can help me.

Dear
Lukas

SDK should enable killing of the application. Chromecast calls this stop

To understand how this library is used sample application is needed

Hello,

I have a problem using this application, and I am almost sure that I'm missing something really trivial.
I use the nuget command to add SharpCaster, all is great, it installs and adds SharpCaster and Newtonsoft Json, all good.

Now I want to reference it at the top of my application, like: Using Sharpcaster.... But I am not able to find it... It would be a huge relief if you could help.

SDK needs to support mute and unmute

User needs to be able to mute, unmute and set volume levels on UI.

They are just causing too much trouble and do not really work when using the nuget package.

So just move them to sample project

Create templated control of Cast Dialog that implements Chromecast Design Checklist
https://developers.google.com/cast/docs/design_checklist#cast-menu

• Cast dialog, not connected (receivers available)
• Cast dialog, connected but not casting
• Cast dialog, while casting

This is more of a question!

I was looking at #50 and just out of curiosity, not directly pointed at @Wind-rider, what do Plex command have to do with Chomecast?

Wouldn't this pollute the project? I myself am a fan of having projects do one thing, and do it good... Having al kinds of features usually makes it hard to maintain, and e.g. a plex change would make other people upgrade the library without the need. Would the Plex stuff work when it was removed from the project into a different one?

Nothing against the functionality... keep up the good work!

Current data model does not really support setting any metadata when loading media

https://blogs.msdn.microsoft.com/dotnet/2016/09/26/introducing-net-standard/

The library and all dependencies seem to be .net 2.0 compatible according to ApiPort.
So once 2.0 is out I will switch to target that one

Add timeline to sample where user can see how far into the media clip they are and use it to seek to different part of the media clip.

http://www.auctor.tv/Archivos/0/Media1/0/1.vtt this url dont work with the captions or subtitles, if you put it in the subtitles, dont work, i think that its a chromecast problem, im not sure what is happening, im not sure if is by using "https" protocol, because a http protocol to put subtitiles dont work.

Hi,

Is it possible to control many chromecasts from the same application ?

It seams that your lib is built "single chromecast", but I would like to drive two or three from the same application...

There maybe other but instance property like this is not thread safe. Because of this possible race condition you might create multiple instances if it's called from multiple threads.

public static ChromecastService Current => _instance ?? (_instance = new ChromecastService());

use this instead

private static Lazy<ChromecastService> _current = new Lazy<ChromecastService>(() => new ChromecastService());  
public static ChromecastService Current { get { return _current .Value; } }

Now there are two solutions (one general one and one for CI).

It would be better to have only one only one .sln file.

I think this can be done in the following way:

• Use the solution configuration manager to create a specific "solution configuration" for CI
• Within that solution configration, uncheck "build" for all sample projects
• Configure AppVeyor to use the CI solution configuration instead of "Debug" or "Release". See https://www.appveyor.com/docs/build-configuration#build-matrix

I have no AppVeyor account so I couldn't test it, but I think that should work.

hi, how can i implement a custom controller to stream a wpf application window?

It would be nice to release your dev branch as pre-release nuget versions so that people can try new features quicker
