Functions
| Name | Description |
|---|---|
| OH_AVScreenCapture_Create (void) | Creates an OH_AVScreenCapture instance. |
| OH_AVScreenCapture_Init (struct OH_AVScreenCapture *capture, OH_AVScreenCaptureConfig config) | Initializes parameters related to an OH_AVScreenCapture instance. |
| OH_AVScreenCapture_StartScreenCapture (struct OH_AVScreenCapture *capture) | Starts screen capture and collects original streams. After calling this function, the application can use the callback listeners OH_AVScreenCaptureOnAudioBufferAvailable and OH_AVScreenCaptureOnVideoBufferAvailable to check whether streams are generated. |
| OH_AVScreenCapture_StopScreenCapture (struct OH_AVScreenCapture *capture) | Stops screen capture. This function is used in pair with OH_AVScreenCapture_StartScreenCapture. After calling this function, the application stops screen capture or screen share and releases the microphone. |
| OH_AVScreenCapture_StartScreenRecording (struct OH_AVScreenCapture *capture) | Starts screen recording and collects encoded streams. NOTE: This function is reserved and will be provided in later versions. |
| OH_AVScreenCapture_StopScreenRecording (struct OH_AVScreenCapture *capture) | Stops screen recording. This function is used in pair with OH_AVScreenCapture_StartScreenRecording. NOTE: This function is reserved and will be provided in later versions. |
| OH_AVScreenCapture_AcquireAudioBuffer (struct OH_AVScreenCapture *capture, OH_AudioBuffer **audiobuffer, OH_AudioCaptureSourceType type) | Obtains an audio buffer. When calling this function, the application must allocate the memory of the corresponding struct size to the audio buffer. |
| OH_AVScreenCapture_AcquireVideoBuffer (struct OH_AVScreenCapture *capture, int32_t *fence, int64_t *timestamp, struct OH_Rect *region) | Obtains a video buffer. An application can call this function to obtain information such as the video buffer and timestamp. |
| OH_AVScreenCapture_ReleaseAudioBuffer (struct OH_AVScreenCapture *capture, OH_AudioCaptureSourceType type) | Releases an audio buffer. |
| OH_AVScreenCapture_ReleaseVideoBuffer (struct OH_AVScreenCapture *capture) | Releases a video buffer. |
| OH_AVScreenCapture_SetCallback (struct OH_AVScreenCapture *capture, struct OH_AVScreenCaptureCallback callback) | Sets a callback to listen for available video buffers and audio buffers and errors that occur during the function calling. |
| OH_AVScreenCapture_Release (struct OH_AVScreenCapture *capture) | Releases an OH_AVScreenCapture instance. This function is used in pair with OH_AVScreenCapture_Create. |
| OH_AVScreenCapture_SetMicrophoneEnabled (struct OH_AVScreenCapture *capture, bool isMicrophone) | Enables or disables the microphone. |
