Monitor ExoPlayer

This documents integration instructions for Google's ExoPlayer library, version 2.x. ExoPlayer versions before 2.0 are not supported. As of version 3.0.0 of Mux's integration with ExoPlayer, only versions of ExoPlayer greater than or equal to 2.10.x are supported.

The Mux integration with ExoPlayer is built on top of Mux's core Java SDK, and the full code can be seen here: muxinc/mux-stats-sdk-exoplayer.

Features

The following data can be collected by the Mux Data SDK when you use the ExoPlayer SDK, as described below.

Supported Features:

• Engagement metrics
• Quality of Experience Metrics
• Available for deployment from a package manager
• Can infer CDN identification from response headers
• Custom Dimensions
• Average Bitrate metrics and renditionchange events
• Request metrics
• Customizable Error Tracking
• Custom Beacon Domain
• Extraction of HLS Session Data

Request Latency is not available.

1Install the Mux Data SDK

Add the Mux SDK to your project using one of the following approaches:

Add Gradle dependency on the Mux ExoPlayer SDK

Add the Mux Maven repository to your Gradle file:

repositories {
    maven {
        url "https://muxinc.jfrog.io/artifactory/default-maven-release-local"
    }
}

Next, add a dependency on the Mux Data ExoPlayer SDK. Supported versions of ExoPlayer are:

• r2.10.6
• r2.11.1
• r2.12.1
• r2.13.1
• r2.14.1
• r2.15.1
• r2.16.1
• r2.17.1
• r2.18.1
• amznPort (see below)

There is typically API compatibility within an ExoPlayer major-minor version, so you should be able to pair one of the versions listed above with any player sharing the same major-minor version (e.g., the ExoPlayer r2.12.1 version of the Mux ExoPlayer SDK works with ExoPlayer r2.12.0 and r2.12.2 equally well).

Add a dependency to your Gradle file using the Mux SDK version and an ExoPlayer version listed above in the following format:

api 'com.mux.stats.sdk.muxstats:MuxExoPlayer_(ExoPlayer SDK version with underscores):(Mux SDK version)'

Example using Mux ExoPlayer SDK 2.7.2 and ExoPlayer version r2.16.1:

api 'com.mux.stats.sdk.muxstats:MuxExoPlayer_r2_16_1:2.7.2'

Amazon ExoPlayer Port

In addition to the versions above, the Mux Data ExoPlayer SDK also supports Amazon's official ExoPlayer port for Amazon Devices. If you are monitoring ExoPlayer on an Amazon device, you can get that version with the following line:

api 'com.mux.stats.sdk.muxstats:MuxExoPlayer_amznPort:(Mux SDK version)'

For an example integration, you can see the demo application within muxinc/mux-stats-sdk-exoplayer which integrates Mux into the ExoPlayer demo application.

2Initialize the monitor with your ExoPlayer instance

Get your ENV_KEY from the Mux environments dashboard.

First, create the CustomerPlayerData and CustomerVideoData objects as appropriate for your current playback

val customerData = CustomerData().apply {
        customerVideoData = CustomerVideoData().apply {
          // Data about this video
          // Add or change properties here to customize video metadata such as title,
          //   language, etc
          videoTitle = "Mux ExoPlayer Android Example"
          // ExoPlayer doesn't provide an API to obtain this, so it must be set manually
          videoSourceUrl = videoUrl
        }
        customerViewData = CustomerViewData().apply {
          // Data about this viewing session
          viewSessionId = UUID.randomUUID().toString()
        }
        customerViewerData = CustomerViewerData().apply {
          // Data about the Viewer and the device they are using
          muxViewerDeviceCategory = "kiosk"
          muxViewerDeviceManufacturer = "Example Display Systems"
          muxViewerOsVersion = "1.2.3-dev"
        }
        customData = CustomData().apply {
          // Add values for your Custom Dimensions.
          // Up to 5 strings can be set to track your own data
          customData1 = "Hello"
          customData2 = "World"
          customData3 = "From"
          customData4 = "Mux"
          customData5 = "Data"
        }

Next, create the MuxStatsExoPlayer object by passing your Context (typically your Activity), your ENV_KEY, the ExoPlayer instance, and the customer data object you just created.

muxStatsExoPlayer = exoPlayer.monitorWithMuxData(
      context = requireContext(),
      envKey = "YOUR_ENV_KEY_HERE",
      playerView = playerView,
      customerData = customerData
    )

If you haven't set your playerView already, do so now. We recommend this in order to determine a number of viewer context values as well as track the size of the video player.

muxStatsExoPlayer.setPlayerView(simpleExoPlayerView.getVideoSurfaceView());

Finally, when you are destroying the player, call the MuxStatsExoPlayer.release() function.

muxStatsExoPlayer.release()

After you've integrated, start playing a video in your player. A few minutes after you stop watching, you'll see the results in your Mux data dashboard. Login to the dashboard and find the environment that corresponds to your env_key and look for video views.

Note For ExoPlayer v2.15 and below

On older supported versions of ExoPlayer, Mux prefers that you pass an instance of SimpleExoPlayer specifically, instead of any ExoPlayer. In the latter case, however, some metrics and errors may not be available, such as upscaling metrics. Updating to ExoPlayer r2.16.0 or higher will remove this limitation

muxStatsExoPlayer = exoPlayer.monitorWithMuxData(
      context = requireContext(),
      envKey = "YOUR_ENV_KEY_HERE",
      playerView = playerView,
      customerData = customerData
    )

or in java:

// Make sure to monitor the player before calling `prepare` on the ExoPlayer instance
muxStatsExoPlayer = new MuxStatsExoPlayer(this, "YOUR_ENV_KEY_HERE", player, playerView, customerData);

3Add Metadata

In the Java SDK, options are provided via the objects within the CustomerData object.

All metadata details are optional, however you'll be able to compare and see more interesting results as you include more details. This gives you more metrics and metadata about video streaming, and allows you to search and filter on important fields like the player version, CDN, and video title.

There is one caveat with ExoPlayer; ExoPlayer does not provide an API to retrieve the current source URL from the player. Due to this, CustomerVideoData has a method allowing you to set via CustomerVideoData.setVideoSourceUrl(String url). Setting this value will allow you to see the source URL as well as the dimension Source Hostname within the dashboard.

For more information, see the Metadata Guide.

4Advanced

Changing the video

There are two cases where the underlying tracking of the video view need to be reset. First, when you load a new source URL into an existing player, and second when the program within a singular stream changes (such as a program within a live stream).

Note: You do not need to change the video info when changing to a different source of the same video content (e.g. different resolution or video format).

New source

When you change to a new video (in the same player) you need to update the information that Mux knows about the current video. Examples of when this is needed are:

• The player advances to the next video in a playlist
• The user selects a different video to play

This is done by calling muxStatsExoPlayer.videoChange(CustomerVideoData) which will remove all previous video data and reset all metrics for the video view. See Metadata for the list of video details you can provide. You can include any metadata when changing the video but you should only need to update the values that start with video.

It's best to change the video info immediately after telling the player which new source to play.

New program (in single stream)

In some cases, you may have the program change within a stream, and you may want to track each program as a view on its own. An example of this is a live stream that streams multiple programs back to back, with no interruptions.

In this case, call muxStatsExoPlayer.programChange(CustomerVideoData). This will remove all previous video data and reset all metrics for the video view, creating a new video view. See Metadata for the list of video details you can provide. You can include any metadata when changing the video but you should only need to update the values that start with video.

Manually set when a video is being played full-screen

For most use cases, the SDK is capable of detecting whether or not a video is being played full-screen. Specifically, it can do so in the case where the player view is the same size as the device display (excepting ActionBars and other framework window decoration).

For other uses cases (non-overlaid controls, window decoration via plain Views, etc) you may need to tell the SDK when the user switches to full-screen.

If you are using SimplePlayerView or a similar ExoPlayer UI component, you can set the full-screen flag from the OnFullScreenModeChangedListener.

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)

    // If you are using SimplePlayerView, StyledPlayerView, etc
    playerView = findViewById(R.id.my_player_view)

    playerView.setFullscreenButtonClickListener { isFullScreen -> 
      // Set presentation based on which mode is requested
      if(isFullScreen) {
        muxStats.presentationChange(MuxSDKViewPresentation.FULLSCREEN)
      } else {
        muxStats.presentationChange(MuxSDKViewPresentation.NORMAL)
      }
      // Handle moving to fullscreen playback with your code
    }
  }

Error tracking

By default, Mux's integration with ExoPlayer automatically tracks fatal errors as thrown by ExoPlayer. If a fatal error happens outside the context of ExoPlayer and you want to track it with Mux, you can call muxStatsExoPlayer.error like this:

// Error code: integer value for the generic type of error that
// occurred.
// Error message: String providing more information on the error
// that occurred.
// For an example, the HTML5 video element uses the
// following: https://developer.mozilla.org/en-US/docs/Web/API/MediaError
// for codes and messages. Feel free to use your own codes and messages
val errorCode = 1
val errorMessage = "A fatal error was encountered during playback"
val errorContext = "Additional information about the error such as a stack trace"
val error = MuxErrorException(errorCode, errorMessage, errorContext)
muxStatsExoPlayer.error(error)

Note that muxStatsExoPlayer.error(MuxErrorException e) can be used with or without automatic error tracking. If your application has retry logic that attempts to recover from ExoPlayer errors then you may want to disable automatic error tracking like this:

muxStatsExoPlayer.setAutomaticErrorTracking(false)

Usage with Google Interactive Media Ads (IMA)

If you are using Google's IMA SDK to play back ads within your Android application, you can configure Mux to monitor the ad performance by passing your instance of AdsLoader to muxStatsExoPlayer.monitorImaAdsLoader(adsLoader).

ExoPlayer r2.12.x and Up

// For example, within the r2.12.x demo application
// PlayerActivity.getAdsLoader
adsLoader = ImaAdsLoader.Builder(context = this)
    /*
     * This replaces `monitorImaAdsLoader` method because in r2.12.x ImaAdsLoader
     * will create google.v3.AdsLoader on adRequest, which means that monitorImaAdsLoader
     * Will always receive null pointer and will be unable to recieve add events.
     */
    .setAdErrorListener(muxStats.getAdErrorEventListener())
    .setAdEventListener(muxStats.getAdEventListener())
    .build()

ExoPlayer pre-r2.12.x

// Within setting up the AdsMediaSource
sdkFactory = ImaSdkFactory.getInstance()
adsLoader = sdkFactory.createAdsLoader(this)
muxStatsExoPlayer.monitorImaAdsLoader(adsLoader)

As of version 1.3.0 and later, the Mux SDK for ExoPlayer supports firing an event when the playback orientation changes. You can trigger this by calling muxStatsExoPlayer.orientationChange(MuxSDKViewOrientation orientation), passing either MuxSDKViewOrientation.LANDSCAPE or MuxSDKViewOrientation.PORTRAIT depending on the current orientation of the player.

Java Build Compatibility

Java and Android Gradle Plugin Build Compatibility

Starting with version 2.6.0, the Mux SDK for ExoPlayer requires JDK 11 and version 7.0 or greater of the Android Gradle Plugin. This is only a requirement for build compatibility. The Mux SDK for ExoPlayer will remain bytecode-compatible with Java 1.8.

If you are updating from version 2.5.9 or lower, you may need to:

• Update Android Studio to version 2020.x or greater
• Update your dependency on the Android Build Tools plugin to 7.0.0 or greater
• Update Gradle in gradle-wrapper.properties to 7.0.2 or greater
• Ensure your Android Studio is using JDK 11:
  • Go to Android Studio Settings
  • Go Build, Execution and Deployment -> BuildTools -> Gradle
  • If the Gradle JDK option is not set to a Java 11 JDK, click the dropdown and select a Java 11 JDK. It should be the default on Studio 2020.x

v0.5.1

• Clean up demo application
• Allow disabling of Sentry reporting for exceptions.

v0.5.0

• Deprecated method muxStatsExoPlayer.getImaSDKListener in favor of muxStatsExoPlayer.monitorImaAdsLoader(adsLoader). The previous method will still work, but you should migrate to the new method as the deprecated method will be removed with the next major version.
• Fix an issue where Google IMA SDK was a hard requirement unintentionally.

• breaking change The signature for getAdaptiveMediaSourceEventListener and getExtractorMediaSourceEventListener has been changed. These methods are used to enable throughput metrics tracking for ExoPlayer versions before r2.8.0, and now require that the streaming protocol type is passed as the first parameter. The type is the same as is returned from this ExoPlayer API call.

v0.3.0

• breaking change The signature for the MuxStatsExoPlayer constructor has changed, and now requires an additional parameter (the first) to be and Android Context reference.
• abstract more core logic into mux-stats-sdk-java
• [build] rename and copy build artifacts

v0.2.2

• add back in previously missing methods to MuxStatsExoPlayer:
