Playback cessation modes

Playback Cessation Modes says what ends playback in a video placement: the ad finishing or the viewer stopping it, the player leaving the viewport, or the player detaching into a floating unit when scrolled away. Sellers send one value in Video.playbackend, a field OpenRTB 2.5 introduced alongside Video.placement.

How to use it

The value tells buyers whether an ad that starts can be expected to finish in view. It matters most for web and in-app players inside scrolling content; on CTV and full-screen placements the player never leaves the screen, so the answer is 1. The three values have not changed since OpenRTB 2.5, and the field is still current in 2.6 even though its companion Video.placement is deprecated.

Common mistakes

Sending 1 for an article player that pauses when scrolled out of view. That behavior is 2.
Sending one value for a player that floats on some devices and not on others. The value should describe the player that will render this impression.

Validation

On OpenRTB 2.6 snapshots, RTBlint reports a value outside this list as openrtb.value.invalid. Paste a request into the tester to check the values you send.
