IPCamera

[Brunz]

Could you create an IPCamera type accessory? I didn't understand how to do it

[Bouke]

That's a good question actually. It seems we don't have the proper accessories / services / characteristics to do that. Those types are generated from a framework, but on my machine (latest Catalina), those types aren't present or we're not looking in the right place.

[Brunz]

Actually there are some in the framework, but I couldn't understand why they are not imported by hap-update. I created them manually, I see the video window on homekit, but I have problems starting the video. Maybe I don't correctly insert the bytes (tlv8).
Sorry for my English.

[Brunz]

This is an example of what is found in "plain-metadata.config" and which is not imported:
<key>camera-rtp-stream-management</key> <dict> <key>Characteristics</key> <dict> <key>Optional</key> <array> <string>active</string> </array> <key>Required</key> <array> <string>selected-stream-configuration</string> <string>setup-stream-endpoint</string> <string>streaming-status</string> <string>supported-audio-stream-configuration</string> <string>supported-rtp-configuration</string> <string>supported-video-stream-configuration</string> </array> </dict> <key>DefaultDescription</key> <string>Camera Stream Management</string> <key>LocalizationKey</key> <string></string> <key>ShortUUID</key> <string>00000110</string> </dict>

We only emit the characteristics that are actually in use by a service. You can remove && whitelistedCharacteristics.contains(name) on this line, so at least you get all the characteristics:

HAP/Sources/HAPUpdate/Inspector.swift

Line 458 in 82f6811

if !blacklistedCharacteristics.contains(name) && whitelistedCharacteristics.contains(name) {

However you still wouldn't have a pre-made accessory and service, as those are not listed in that framework. Can you share what your configuration looks like so far, to get them listed in the Home app?

[Brunz]

Great Bouke!
"camera-rtp-stream-management" is a Service and YES this is in the "BlacklistFromApplications".
I make a change to the inspector and try to import again.

The test implementation is attached to the message.
Camera.swift.zip

[Brunz]

ok, I have removed camera-rtp-stream-management from blacklistAppServices

if var index = blacklistAppServices.firstIndex(where: {$0 == "camera-rtp-stream-management"}){ blacklistAppServices.remove(at: index) }

..and now I have Service and Characteristics into Generated.swift

After I modified the file "CharacteristicValueType" in this way:

extension Data: CharacteristicValueType, JSONValueTypeConvertible { public init?(value: Any) { //fatalError("How does deserialization of Data work?") if let v = value as? String, let vd = Data(base64Encoded: v){ self = vd } return nil } static public let format = CharacteristicFormat.data public var jsonValueType: JSONValueType { //fatalError("How does serialization of Data work?") return self.base64EncodedString() } }

and now I'm at the point of before :) But it's much cleaner

[Bouke]

Out of curiosity; what does your code look like now to initialize the camera accessory?

[Brunz]

this:
acc.append(Accessory.RTPCamera(info: Service.Info(name: "Camera", serialNumber: "00012")))
Append the accessory "RTPCamera" in Device.accessories array

And intercept "resource" in router func, for send camera snapshot to controller:
func router(_ routes: [Route]) -> Responder {
return { connection, request in
if(request.url.path == "/resource"){
...

The preview is ok now, the streaming rtsp still no.

[Brunz]

But maybe I make some mistakes, because the controller should send me a response to the configuration of the Camera, but I don't see. If you want I can send the project, but it is compiled only on iOS.

@Brunz Did you ever get this to work?

[Brunz]

Hi @joshsnelling ,

I implemented all the missing piece of protocol but I was unable to send the video in the correct format. I have also tried using ffmpeg for iOS to configure RTS streaming, but there are too many properties to configure and I am not an expert.

@Brunz Hi! Any progress with camera accessory implementation?
