captureAudio

屏幕共享时是否采集系统音频：

• true: 采集系统音频。
• false: （默认）不采集系统音频。

信息

• 受系统限制，采集系统音频仅适用于 Android API 级别为 29 及以上，即 Android 10 及以上。
• 为提高屏幕共享时采集系统音频的成功率，请确保你已调用 setAudioScenario 方法并设置音频场景为 AUDIO_SCENARIO_GAME_STREAMING。

captureVideo

屏幕共享时是否采集屏幕：

• true:（默认）采集屏幕。
• false: 不采集屏幕。

信息

受系统限制，采集屏幕仅适用于 Android API 级别为 21 及以上，即 Android 5 及以上。
