Agora supports setting the channel name used for generating a token as a wildcard character. The token generated can be used to join any channel if you use the same user id. In scenarios involving multiple channels, such as switching between different channels, using a wildcard token can avoid repeated application of tokens every time users joining a new channel, which reduces the pressure on your token server. See [Wildcard tokens](https://docportal.shengwang.cn/cn/live-streaming-premium-4.x/wildcard_token?platform=All%20Platforms). + +
All 4.x SDKs support using wildcard tokens.
+ +4. **Preloading channels** + + This release adds `preloadChannel` and `preloadChannelWithUserAccount` methods, which allows a user whose role is set as audience to preload channels before joining one.

See [Wildcard tokens](https://docportal.shengwang.cn/cn/live-streaming-premium-4.x/wildcard_token?platform=All%20Platforms). + +5. **Customized background color of video canvas** + + In this release, the `backgroundColor` member has been added to `VideoCanvas`, which allows you to customize the background color of the video canvas when setting the properties of local or remote video display. + + +#### Improvements + +1. **Improved camera capture effect** + + This release has improved camera capture effect in the following aspects: + + 1. Support for camera exposure adjustment + + This release adds `isCameraExposureSupported` to query whether the device supports exposure adjustment and `setCameraExposureFactor` to set the exposure ratio of the camera. + + 2. Optimization of default camera selection (iOS) + + Since this release, the default camera selection behavior of the SDK is aligned with that of the iOS system camera. If the device has multiple rear cameras, better shooting perspectives, zooming capabilities, low-light performance, and depth sensing can be achieved during video capture, thereby improving the quality of video capture. + + +2. **Virtual Background Algorithm Upgrade** + + This version has upgraded the portrait segmentation algorithm of the virtual background, which comprehensively improves the accuracy of portrait segmentation, the smoothness of the portrait edge with the virtual background, and the fit of the edge when the person moves. In addition, it optimizes the precision of the person's edge in scenarios such as meetings, offices, homes, and under backlight or weak light conditions. + + This version reduces the memory usage of the virtual background feature. Compared to the previous version, the memory consumption of the app during the use of the virtual background feature on low-end devices has been reduced by approximately 4% to 10% (specific values may vary depending on the device model and platform). + +3. **Screen sharing scenario optimization** + + This release also optimizes the video encoding configuration in screen sharing scenarios. When users customize the `width` and `height` properties of the video, the SDK rounds down the actual encoding resolution while maintaining the aspect ratio of the video and the screen, ensuring that the final encoding resolution does not exceed the user-defined encoding resolution, thereby improving the accuracy of billing for screen sharing streams. + +4. **Channel media relay** + + The number of target channels for media relay has been increased to 6. When calling `startOrUpdateChannelMediaRelay` and `startOrUpdateChannelMediaRelayEx`, you can specify up to 6 target channels. + +5. **Enhancement in video codec query capability** + + To improve the video codec query capability, this release adds the `codecLevels` member in `CodecCapInfo`. After successfully calling `queryCodecCapability`, you can obtain the hardware and software decoding capability levels of the device for H.264 and H.265 video formats through `codecLevels`. + + +**Other Improvements** + +This release includes the following additional improvements: + +- Optimizes the logic of handling invalid parameters.

This method can switch the audio route from a Bluetooth headphone to the earpiece, wired headphone or speaker in communication volume mode ([`MODE_IN_COMMUNICATION`](https://developer.android.google.cn/reference/kotlin/android/media/AudioManager?hl=en#mode_in_communication)). (Android) +- The SDK automacially adjusts the frame rate of the sending end based on the screen sharing scenario. Especially in document sharing scenarios, this feature avoids exceeding the expected video bitrate on the sending end to improve transmission efficiency and reduce network burden. +- To help users understand the reasons for more types of remote video state changes, the `remoteVideoStateReasonCodecNotSupport` enumeration has been added to the `onRemoteVideoStateChanged` callback, indicating that the local video decoder does not support decoding the received remote video stream. + +#### Issues fixed + +This release fixed the following issues: + +- Occasional failure of joining a channel when the local system time was not set correctly. +- When calling the `playEffect` method to play two audio files using the same `soundId`, the first audio file was somtimes played repeatedly. +- Calling `takeSnapshotEx` once receives the `onSnapshotTaken` callback for multiple times. +- When the host called the `startAudioMixing` method to play music, sometimes the host couldn't hear the music while the remote users could hear it.
