IMA SDK uses Active View reporting to measure ad viewability.
Active View receives measurements on theVideoStreamPlayerinstance passed to theStreamDisplayContainer.
You can verify the SDK's ability to capture viewability signals by looking for network requests tohttps://pagead2.googlesyndication.com/pcs/activeviewand checking themtosparameter.
A sample stream is available for testing viewability using CMS ID "2556080" and video ID "tears-of-steel-omid".
The IMA SDK must be able to tell when ads are visible to users so that it can
send the correct signals back to the ad server. IMA usesActive View reportingto measure the viewability of ads. This guide explains how Active View
reporting works with IMA, as well as how to verify that the SDK is able to
correctly capture viewability signals.
Active View receives measurements on thatVideoStreamPlayer(getLocationOnScreenandgetGlobalVisibleRect).
Verifying that the SDK can measure ad viewability
To check whether that the SDK is able to capture viewability signals, look for
network requests sent tohttps://pagead2.googlesyndication.com/pcs/activeviewand check for themtosparameter. For more information, seeMonitor Active View measurement.
The following sample stream is available for viewability testing:
CMS ID: "2556080", video ID: "tears-of-steel-omid"
To test using this stream, first check the network logs forima-test-verification.jsto be downloaded and then a ping fired tohttps://pagead2.googlesyndication.com/pagead/gen_204at the start of ad
playback.

This involves creating a `StreamDisplayContainer` with a `VideoStreamPlayer`, enabling Active View to measure it using `getLocationOnScreen` and `getGlobalVisibleRect`. Verification involves checking `HTTP` requests for `active_view_vide_measurable_impression` and the `mtos` parameter. A test stream (CMS ID: \"2556080\", video ID: \"tears-of-steel-omid\") is provided; monitor network logs for `ima-test-verification.js` download and a ping to `https://pagead2.googlesyndication.com/pagead/gen_204`.\n"]]
