PCast™ Express

The PCast™ Express extends the PCast™ API to provide a single-step configuration based API for:

Publishing local media
Subscribing to published streams

This API is intended to be used as a supplement to the Room Express although it can be used to stream all on its own.

Initializing

Swift
import PhenixSdk

let pcastExpressOptions = PhenixPCastExpressFactory.createPCastExpressOptionsBuilder()
    .withAuthenticationToken("DIGEST:eyJhc...")
    .buildPCastExpressOptions()

let pcastExpress = PhenixPCastExpressFactory.createPCastExpress(pcastExpressOptions)

PhenixPCastExpressOptionsBuilder

Name	Type	Default	Description
withAuthenticationToken (required)	NSString		The authentication token generated using the Phenix EdgeAuth library.
withUnrecoverableErrorCallback (optional)		PhenixPCastExpressUnrecoverableErrorCallback	Function to be called when authentication fails or a failure occurs that is unrecoverable.
withPCastUri (optional)	NSString		Allows overriding default PCast™ URI.
withPCastInitializationOptions (optional)	PhenixPCastInitializeOptions		Use custom options when initializing PCast™.
buildPCastExpressOptions	none		Builds the `PhenixPCastExpressOptions`

Publishing Local Media

Publish local user media:

Camera
Microphone

Swift
import PhenixSdk

let pcastExpress: PhenixPCastExpress = ...  // previously obtained

let userMediaConstraints = PhenixUserMediaOptions()
userMediaConstraints.video.enabled = true
userMediaConstraints.video.capabilityConstraints[PhenixDeviceCapability.facingMode.rawValue] =
    [PhenixDeviceConstraint.initWith(PhenixFacingMode.user)]
userMediaConstraints.audio.enabled = true
userMediaConstraints.audio.capabilityConstraints[PhenixDeviceCapability.audioEchoCancelationMode.rawValue] =
    [PhenixDeviceConstraint.initWith(PhenixAudioEchoCancelationMode.on)]

let publishOptions = PhenixPCastExpressFactory.createPublishOptionsBuilder()
    .withStreamToken("DIGEST:eyJhc...")
    .withMediaConstraints(userMediaConstraints)
    .buildPublishOptions()

pcastExpress.publish(publishOptions) { (status: PhenixRequestStatus, publisher: PhenixExpressPublisher?) in
  if status == .ok {
    // Do something with publisher
  } else {
    // Handle error
  }
}


// Create a publisher with an automatically started preview renderer
let renderLayer: CALayer = ...  // previously obtained
let publishOptionsWithPreview = PhenixPCastExpressFactory.createPublishOptionsBuilder()
    .withStreamToken("DIGEST:eyJhc...")
    .withMediaConstraints(userMediaConstraints)
    .withPreviewRenderer(renderLayer)
    .buildPublishOptions()

pcastExpress.publish(withPreview: publishOptionsWithPreview) {
    (status: PhenixRequestStatus, publisher: PhenixExpressPublisher?, preview: PhenixRenderer?) in
  if status == .ok {
    // Do something with publisher and preview renderer
  } else {
    // Handle error
  }
}

Notes:

The preview renderer will already have been started by the time it is received by your callback
The publisher will remain active for as long as you keep a reference to it

Subscribing to Published Media

Subscribe to streams published with the Phenix platform

Swift
import PhenixSdk

let pcastExpress: PhenixPCastExpress = ...  // previously obtained
let renderLayer: CALayer = ...  // previously obtained

let subscribeOptions = PhenixPCastExpressFactory.createSubscribeOptionsBuilder()
    .withStreamId("us-west#us-west1-b.zzzzzzzz.20000000.xxxxxxxx")
    .withStreamToken("DIGEST:eyJhc...")
    .withRenderer(renderLayer)
    .buildSubscribeOptions()

pcastExpress.subscribe(subscribeOptions) { (status: PhenixRequestStatus, subscriber: PhenixExpressSubscriber?, renderer: PhenixRenderer?) in
  if status == .ok {
    // Do something with subscriber

    if let renderer = renderer {
      // Returned if `withRenderer...` option was enabled - Do something with renderer
    }
  } else {
    // Handle error
  }
}

Notes:

The renderer will already have been started by the time it is received by your callback
If a renderer is provided, your PhenixExpressSubscriber will be kept alive for as long as you are referencing that renderer. There is no need to also store a reference to the subscriber in that case
Once subscriber and renderer references have been released, the renderer and subscription will automatically be stopped

callback (required)	function	Callback for error/success handling

Name	Type	Default	Description
withStreamId (required)	NSString		The stream ID of the published stream
withStreamToken (required)	NSString		The subscribe token generated using the Phenix EdgeAuth library.
withRenderer (optional)	CALayer		Render layer on which to display stream. If none of the `withRenderer...` methods are called, no renderer will be instantiated.

Monitor

Note: On iOS, the monitor options are currently ignored, but the callbacks for stream setup and stream ended will be triggered.

Monitor callbacks and options can be passed to subscribe and publish options builders. The first callback gets invoked only when we internally fail to setup a stream. The second callback gets invoked whenever a stream ends, whether it is due to failure or not. The retry PhenixOptionalAction allows you to retry publishing or subscribing the failed stream. You must test first whether there is a retry action present by calling isPresent as it may not be possible to retry the stream (example: a stream that ended normally cannot be retried). You may call dismiss on the retry action, but you do not have to (the action is automatically dismissed when no longer referenced). You also may defer invoking the retry action.

Example Monitor for subscribing

Swift
import PhenixSdk

let monitorOptions = PhenixPCastExpressFactory.createMonitorOptionsBuilder().buildMonitorOptions();

let subscribeOptions = PhenixPCastExpressFactory.createSubscribeOptionsBuilder()
    .withStreamId("us-west#us-west1-b.zzzzzzzz.20000000.xxxxxxxx")
    .withStreamToken("DIGEST:eyJhc...")
    .withMonitor({ (status: PhenixRequestStatus, retry: PhenixOptionalAction?) in
          // Stream failed to setup, check if retry is a possibility:
          if let retry = retry, retry.isPresent() {
            if determineWhetherToRetry() {
              retry.perform()
            } else {
              // Not technically necessary, but here for clarity
              retry.dismiss()
            }
          }
        },
        { (reason: PhenixStreamEndedReason, description: String?, retry: PhenixOptionalAction?) in
          // Stream has ended, check if due to failure
          if let retry = retry, retry.isPresent() {
            if reason == .failed {
              retry.perform()
            } else {
              // Not technically necessary, but here for clarity
              retry.dismiss()
            }
          }
        },
        monitorOptions)
    .buildSubscribeOptions()

PhenixOptionalAction

Name	Signature	Returns	Description
perform	()	void	Performs the action. This will cause a failure if `isPresent` is false.
dismiss	()	void	Dismisses the action (if any). Can be called multiple times, will result in `isPresent` to return false. Dropping reference to PhenixOptionsAction has same effect.
isPresent	()	bool	Indicates whether an action can be performed.

PhenixMonitorSetupFailedCallback Callback Arguments

Name	Type	Description
status	PhenixRequestStatus	The status of the operation.
retry	PhenixOptionalAction	Optionally allow retrying the failed stream.

PhenixMonitorStreamEndedCallback Callback Arguments

Name	Type	Description
reason	PhenixStreamEndedReason	Reason for stream ended.
description	NSString	Optional additional ended reason description. Carries custom message.
retry	PhenixOptionalAction	Optionally allow retrying the failed stream. For normally ended streams `isPresent` will always return false.

Express Get User Media

Get local user media. For now this is merely a wrapper around Get Local User Media.

Swift
import PhenixSdk

let pcastExpress: PhenixPCastExpress = ...  // previously obtained

let userMediaOptions = PhenixUserMediaOptions()

pcastExpress.getUserMedia(userMediaOptions) { (status: PhenixRequestStatus, userMedia: PhenixUserMediaStream?) in
  if status == .ok {
    // Do something with user media stream
  } else {
    // Handle error
  }
}

Express Get User Media Parameters

Name	Type	Description
options (required)	PhenixUserMediaOptions	User media options
callback (required)	function	Callback for error/success handling

Express Get User Media Callback Arguments

Name	Type	Description
status	PhenixRequestStatus	The status of the operation.
userMedia	PhenixUserMediaStream	User media stream

Get PCast

Get the underlying instance of the PCast™. This is preferred to creating another instance as this will introduce more overhead.

Swift
import PhenixSdk

let pcastExpress: PhenixPCastExpress = ...  // previously obtained

let pcast = pcastExpress.pcast

Clean up

Subscribers and publishers are kept alive for as long as they are being referenced in your app. PhenixPCastExpress will only shutdown once it is no longer being referenced.

Process Raw Frames with Frame Ready API

The Frame Ready API allows access to raw unencoded audio and video frames on the publisher as well as subscriber side. This enables use cases such as the following:

Injection of raw frames from a custom source
Composition of raw frames (e.g. for applying watermarks, or stickers)
Application of effects (e.g. changing audio volume, applying video filters)
Controlling playback (e.g. temporary slow-motion, pause)

Please note: Any processing needs to keep up with the incoming frame rate; otherwise some of the incoming frames will be dropped to compensate.

Process Raw Frames Publisher side

The API is attached to PhenixUserMediaStream and called setFrameReadyCallback. A track needs to be passed in to indicate for which frames to receive notifications.

PhenixUserMediaStream (via its contained PhenixMediaStream) provides access to the currently available tracks via getVideoTracks and getAudioTracks.

Example Code for processing video raw frames

Swift
import PhenixSdk

let userMediaStream: PhenixUserMediaStream = ... // previously obtained

// Assume there is at least one video track:
let videoTrack = userMediaStream.mediaStream.getVideoTracks()[0]

// 1) Example showing how read incoming video frame and produce and outgoing one:
userMediaStream.setFrameReadyCallback(videoTrack) { (frameNotification: PhenixFrameNotification?) in
  frameNotification?.read { (inputFrame: CMSampleBuffer?) in
    let pixelBuffer: CVPixelBuffer = CMSampleBufferGetImageBuffer(inputFrame!)!

    // Process, manipulate pixel buffer
    // ...

    // Assume we generate an output CVPixelBuffer, which may or may not be based
    // on the incoming frame:
    let outputPixelBuffer: CVPixelBuffer = ...

    // Assemble an output frame using the same timestamps as the input sample buffer:
    let presentationTimeStamp = CMSampleBufferGetPresentationTimeStamp(inputFrame!)
    let duration = CMSampleBufferGetDuration(inputFrame!)

    var sampleTimingInfo = CMSampleTimingInfo.init(
        duration: duration,
        presentationTimeStamp: presentationTimeStamp,
        decodeTimeStamp: CMTime.invalid)

    var formatDescription: CMFormatDescription? = nil
    CMVideoFormatDescriptionCreateForImageBuffer(
        allocator: kCFAllocatorDefault,
        imageBuffer: outputPixelBuffer,
        formatDescriptionOut: &formatDescription)

    var outputFrame: CMSampleBuffer? = nil
    CMSampleBufferCreateReadyWithImageBuffer(
        allocator: kCFAllocatorDefault,
        imageBuffer: outputPixelBuffer,
        formatDescription: formatDescription!,
        sampleTiming: &sampleTimingInfo,
        sampleBufferOut: &outputFrame)

    frameNotification?.write(outputFrame)
  }
}

// 2) Example showing how we can just directly write output frames from a custom source without the need to
//    read the incoming frame:
userMediaStream.setFrameReadyCallback(videoTrack) { (frameNotification: PhenixFrameNotification?) in
  // Assume we have a custom source that is able to provide CMSampleBuffer:
  let outputFrame: CMSampleBuffer? = ...

  frameNotification?.write(outputFrame)
}

// 3) Example showing how we can stop frames from getting propagated by instructing the notification
//    to drop them:
userMediaStream.setFrameReadyCallback(videoTrack) { (frameNotification: PhenixFrameNotification?) in
  // We want to prevent frames from getting propagated further:
  frameNotification?.drop()
}

// 4) Example showing how to read and convert incoming frames to a specific pixel format:
userMediaStream.setFrameReadyCallback(videoTrack) { (frameNotification) in
  frameNotification?.read(with: .BGRA) { (inputFrame: CMSampleBuffer?) in
    let bgraPixelBuffer: CVPixelBuffer = CMSampleBufferGetImageBuffer(inputFrame!)!

    // ...
  }
}

Example Code for processing audio raw frames

Swift
import PhenixSdk

let userMediaStream: PhenixUserMediaStream = ... // previously obtained

// Assume there is at least one audio track:
let audioTrack = userMediaStream.mediaStream.getAudioTracks()[0]

// 1) Example showing how read incoming audio frame and produce and outgoing one:
userMediaStream.setFrameReadyCallback(audioTrack) { (frameNotification: PhenixFrameNotification?) in
  frameNotification?.read { (inputFrame: CMSampleBuffer?) in
    let blockBuffer = CMSampleBufferGetDataBuffer(inputFrame!)

    var totalLength = Int()
    var lengthAtOffset = Int()
    var dataPointer: UnsafeMutablePointer<Int8>? = nil

    guard CMBlockBufferGetDataPointer(
        blockBuffer!,
        atOffset: 0,
        lengthAtOffsetOut: &lengthAtOffset,
        totalLengthOut: &totalLength,
        dataPointerOut: &dataPointer) == kCMBlockBufferNoErr && lengthAtOffset == totalLength else {
      // Handle error, unexpected buffer length
      return
    }

    // Verify audio format:
    guard let formatDescription: CMAudioFormatDescription =
        CMSampleBufferGetFormatDescription(inputFrame!) else {
      return
    }
    guard let audioStreamBasicDescription =
        CMAudioFormatDescriptionGetStreamBasicDescription(formatDescription) else {
      return
    }
    guard (audioStreamBasicDescription.pointee.mFormatFlags & kAudioFormatFlagIsSignedInteger)
            == kAudioFormatFlagIsSignedInteger &&
          audioStreamBasicDescription.pointee.mBitsPerChannel == 16 else {
      return
    }

    // Raw samples are contained in `dataPointer` as Int16 values
    ...

    // Assume we generate an output CMBlockBuffer, which may or may not be based
    // on the incoming audio frame, and which as the same audio format and same
    // length as the incoming frame:
    let outputAudioBuffer: CMBlockBuffer = ...

    let presentationTimeStamp = CMSampleBufferGetPresentationTimeStamp(inputFrame!)
    let numberOfSamples =
        totalLength /
        Int(audioStreamBasicDescription.pointee.mChannelsPerFrame * audioStreamBasicDescription.pointee.mBitsPerChannel / 8)

    var outputFrame: CMSampleBuffer? = nil
    CMAudioSampleBufferCreateReadyWithPacketDescriptions(
        allocator: kCFAllocatorDefault,
        dataBuffer: outputAudioBuffer,
        formatDescription: formatDescription,
        sampleCount: numberOfSamples,
        presentationTimeStamp: presentationTimeStamp,
        packetDescriptions: nil,
        sampleBufferOut: &outputFrame)

    frameNotification?.write(outputFrame)
  }
}

// Other examples would look very similar to video

Frame Ready Callback Arguments

This callback gets invoked for each frame that is passing through.

Name	Type	Description
frameNotification	PhenixFrameNotification	Object representing the current frame

Frame Notification

Represents the current frame. Allows for reading, writing, and dropping.

Name	Signature	Returns	Description
read	(ReadFrameCallback)	void	Retrieves current raw frame in form of a CMSampleBufferRef
readWithFormat	(PhenixMediaFormat, ReadFrameCallback)	void	Retrieves current raw frame in form of a CMSampleBufferRef
write	(CMSampleBufferRef)	void	Writes back a processed or newly generated frame. The frame can have a different resolution and timestamps (the buffer attributes are expected to be set correctly)
drop	()	void	Instructs stream to drop the current frame

Read Frame Callback Arguments

Receives the current raw frame.

Name	Type	Description
frame	CMSampleBufferRef	The raw audio or video frame

Media Format

Strategy	Description
PhenixMediaFormatI420	FourCC planar pixel format YUV-I420, corresponds to Apple kCVPixelFormatType_420YpCbCr8Planar
PhenixMediaFormatNV12	FourCC planar pixel format YUV-NV12, corresponds to Apple kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange
PhenixMediaFormatBGRA	FourCC pixel format RGB-ARGB, corresponds to Apple kCVPixelFormatType_32BGRA

Process Raw Frames Subscriber side

The Frame Ready API on the subscriber side can be accessed via the renderer, which offers an analoguous setFrameReadyCallback method to the Publisher Side.

When using the Express API, you can access the stream tracks directly via the Express Subscriber. Otherwise, tracks can be accessed via the PhenixMediaStream object.

The example code is somewhat abbreviated as the contents of the Frame Ready callbacks would look the same as for the Publisher Side.

Example Code for hooking up frame-ready callback with a PhenixMediaStream object

Swift
import PhenixSdk

let mediaStream: PhenixMediaStream = ... // previously obtained
let renderer: PhenixRenderer = ... // previously obtained

// Assume there is at least one video track:
let videoTrack = mediaStream.getVideoTracks()[0]

renderer.setFrameReadyCallback(videoTrack, ...
// Remainder of code identical to Publish Side

Example Code for hooking up frame-ready callback with a PhenixExpressSubscriber object

Swift
import PhenixSdk

let expressSubscriber: PhenixExpressSubscriber = ... // previously obtained
let renderer: PhenixRenderer = ... // previously obtained

// Assume there is at least one video track:
let videoTrack = expressSubscriber.getVideoTracks()[0]

renderer.setFrameReadyCallback(videoTrack, ...
// Remainder of code identical to Publish Side

Limit Bandwidth

The outgoing or incoming video bandwidth can be limited on the publisher and subscriber side.

Limit Bandwidth Publisher side

The published video bitrate can be limited temporarily if needed. The returned disposable allows to control for how long the limitation should stay in effect. If limitBandwidth is called multiple times before any of the previous disposables are released, then only the most recent override will remain in effect until its disposable is released. Relasing any of the disposables from earlier limitBandwidth calls will have no effect.

Example Code for limiting video bandwidth with a PhenixPublisher object

Swift
import PhenixSdk

// Previously obtained
let publisher: PhenixPublisher = ...

// Limit video bitrate to 200kbps for 10 seconds
var disposable = publisher.limitBandwidth(200000)

DispatchQueue.main.asyncAfter(deadline: .now() + 10) {
  // Dropping the disposable will undo the bandwidth limitation
  disposable = nil
}

Example Code for limiting video bandwidth with a PhenixExpressPublisher object

Swift
import PhenixSdk

// Previously obtained
let expressPublisher: PhenixExpressPublisher = ...

// Limit video bitrate to 200kbps for 10 seconds
var disposable = expressPublisher.limitBandwidth(200000)

DispatchQueue.main.asyncAfter(deadline: .now() + 10) {
  // Dropping the disposable will undo the bandwidth limitation
  disposable = nil
}

Parameters

Name	Type	Description
bandwidthLimitInBps (required)	UInt64	Maximum bitrate limit in bps for video

Limit Bandwidth Subscriber side

Invoking limitBandwidth on a subscriber will inform the publishing side to lower the video bandwidth to try to match the requested value. The API is attached to PhenixMediaStreamTrack. The semantics with regards to the disposable returned by the API are identical to the publisher side.

Notes:

Whether a publisher is able to meet the requested bandwidth also depends on the stream capabilities for the given publisher. For MBR (multi-bitrate publisher capability enabled) the publisher will be able to fairly closely match the requested bitrate. With SBR (without multi-bitrate capability) the bit rate received by the subscriber may not match as well.
The video bitrate will not immediately change after limitBandwidth has been invoked. Similarly, once the disposable has been released, it may take several seconds for the bitrate to recover.

Example Code for limiting video bandwidth with a PhenixMediaStream object

Swift
import PhenixSdk

// Previously obtained
let subscriber: PhenixMediaStream = ...

// Limit video bitrate to 200kbps for 10 seconds
// We assume there is at least one video track on this stream
var disposable = subscriber.getVideoTracks()[0].limitBandwidth(200000)

DispatchQueue.main.asyncAfter(deadline: .now() + 10) {
  // Dropping the disposable will undo the bandwidth limitation
  disposable = nil
}

Example Code for limiting video bandwidth with a PhenixExpressSubscriber object

Swift
import PhenixSdk

// Previously obtained
let subscriber: PhenixExpressSubscriber = ...

// Limit video bitrate to 200kbps for 10 seconds
// We assume there is at least one video track on this stream
var disposable = subscriber.getVideoTracks()[0].limitBandwidth(200000)

DispatchQueue.main.asyncAfter(deadline: .now() + 10) {
  // Dropping the disposable will undo the bandwidth limitation
  disposable = nil
}

Parameters

Name	Type	Description
bandwidthLimitInBps (required)	UInt64	Maximum bitrate limit in bps for video
