Summary
Functions
| Name | Description |
|---|---|
| OH_AVBuffer * OH_AVBuffer_Create (int32_t capacity) | Creates an OH_AVBuffer instance. The caller must call OH_AVBuffer_Destroy to manually release the OH_AVBuffer instance returned. |
| OH_AVErrCodeOH_AVBuffer_Destroy (OH_AVBuffer *buffer) | Releases an OH_AVBuffer instance. |
| OH_AVErrCodeOH_AVBuffer_GetBufferAttr (OH_AVBuffer *buffer, OH_AVCodecBufferAttr *attr) | Obtains the high-frequency attribute of a data buffer. |
| OH_AVErrCodeOH_AVBuffer_SetBufferAttr (OH_AVBuffer *buffer, const OH_AVCodecBufferAttr *attr) | Sets the high-frequency attribute for a data buffer. |
| OH_AVFormat * OH_AVBuffer_GetParameter (OH_AVBuffer *buffer) | Obtains the frame parameter of a data buffer. |
| OH_AVErrCodeOH_AVBuffer_SetParameter (OH_AVBuffer *buffer, const OH_AVFormat *format) | Sets the frame parameter for a data buffer. |
| uint8_t * OH_AVBuffer_GetAddr (OH_AVBuffer *buffer) | Obtains the virtual address of a data buffer. |
| int32_t OH_AVBuffer_GetCapacity (OH_AVBuffer *buffer) | Obtains the capacity of a data buffer. |
| OH_NativeBuffer * OH_AVBuffer_GetNativeBuffer (OH_AVBuffer *buffer) | Obtains the pointer of an OH_NativeBuffer instance. |
