Video pause reason
A video stream can be paused for various reasons, such as a user choosing to pause the video or the camera being disabled.
For both 1-to-1 calls and group calls, the reason for video pause is delivered in the event callbacks when video is paused. The PlanetKitVideoPauseReason enum defines the following reasons for video pause.
| Enum constant | Description |
|---|---|
user | When a peer calls pauseMyVideo() |
interrupt | When the app enters background status |
enableVideoResponse | (Only for 1-to-1 calls) The user's video is paused after the peer enabled a video call. For more information, refer to Enable video call from audio call. |
cameraInactive | When the camera device is being disabled |
hold | When a peer calls hold(). For more information, refer to Hold. |
Interface changes
The following changes have been made to the APIs related to the video pause event.
| SDK version | 1-to-1 call | Group call |
|---|---|---|
| PlanetKit 4.4 or higher | peerVideoDidPausepeerVideoDidResume | peersVideoDidUpdate |
| PlanetKit 4.3 | evtPeerVideoPausedevtPeerVideoResumed | evtPeerVideoPausedevtPeerVideoResumed |
| PlanetKit 4.2 or lower | evtPeerUpdated | evtPeerUpdated |
Up to PlanetKit 4.3, in a group call, the shareVideoPause property (default value is true) in the conference parameter must be set to false to disable sharing the user's own video pause status with others. The shareVideoPause property has been removed since PlanetKit 4.4.
