| 1025 | Screen sharing failed. Please use Android 5.0 or above if the device is on Android or use iOS 11.0 or above if the device is on iOS |
| 1026 | No permission to upstream substream |
| 1027 | Another user is upstreaming substream |
| 1028 | Screen sharing was stopped by the system |

| 1030 | Unsupported video resolution |
| 1031 | Failed to encode audio frames; for example, the SDK could not process the custom audio data passed in |
| 1032 | Unsupported audio sample rate |
