What does Picture-in-picture mean?
Picture-in-picture is a supported interface mode that keeps video in a small floating window while the user performs other tasks. It requires platform and app implementation, so its presence in another video app does not prove the current player supports it.
Why it matters
The small window remains playback and can continue using data or an active connection. It is different from a static preview image and from full-screen mirroring to another device. Read the app’s documented entry and exit controls, and review permissions narrowly rather than enabling unrelated access to force the feature.
A practical example
For example, leaving a player with the home button may stop video, open a floating window or leave only audio, depending on implementation. State the observed behaviour precisely when asking for help instead of describing all three outcomes as the same multitasking issue.
