Express SDK provides you with a series of interfaces to enable and disable related devices. The specific descriptions are as follows:

Device	Interface	Description	Precautions
Camera	`enableCamera`	Enable or disable the camera on your (local device).	`enableCamera` will truly switch the camera device, so frequent use is not recommended. When you need to release the camera device, you can call this interface.
Video Screen	`mutePublishStreamVideo`	When pushing stream, whether to send video data. true means not to send.	When the broadcaster does not want to publish their own screen, you can call this interface. This interface will not truly switch the device, nor will it truly stop pushing stream.
Video Screen	`mutePlayStreamVideo`	When playing stream, whether to play video data in a certain stream. true means not to play.	- When the audience does not want to see a certain person's screen, you can call this interface.- This interface will not truly stop playing stream.
Microphone	`enableAudioCaptureDevice`	Enable or disable the microphone on your (local device).	The difference from `muteMicrophone` is that this interface will truly enable or disable the microphone device. If you need to switch frequently, it is recommended to use the `muteMicrophone` interface.
Audio	`muteMicrophone`	Whether to mute your (local device) microphone.	The difference from `enableAudioCaptureDevice` is that `muteMicrophone` does not truly turn off the microphone, but only replaces the audio data collected by the device with silent data.
	`mutePublishStreamAudio`	When pushing stream, whether to send audio data. true means not to send.	When the broadcaster does not want to publish their own voice, you can use this interface. This interface will not truly switch the device, nor will it truly stop pushing stream.
	`mutePlayStreamAudio`	When playing stream, whether to play audio data in a certain stream. true means not to play.	- When the audience does not want to hear a certain person's voice, you can use this interface.- This interface will not truly stop playing stream.
Speaker/Headphone	`muteSpeaker`	Whether to mute your (local device) speaker/headphone.	After muting, all sounds from the SDK will not be played, including stream pulling, media player, etc.
