Summary
Functions
| Name | Description |
|---|---|
| OH_AVCodec * OH_AudioEncoder_CreateByMime (const char *mime) | Creates an audio encoder instance based on a Multipurpose Internet Mail Extension (MIME) type. |
| OH_AVCodec * OH_AudioEncoder_CreateByName (const char *name) | Creates an audio encoder instance based on an encoder name. |
| OH_AVErrCode OH_AudioEncoder_Destroy (OH_AVCodec *codec) | Clears the internal resources of an audio encoder and destroys the encoder instance. |
| OH_AVErrCode OH_AudioEncoder_SetCallback (OH_AVCodec *codec, OH_AVCodecAsyncCallback callback, void *userData) | Sets an asynchronous callback so that your application can respond to events generated by an audio encoder. |
| OH_AVErrCode OH_AudioEncoder_Configure (OH_AVCodec *codec, OH_AVFormat *format) | Configures an audio encoder. Typically, you need to configure the description information about the audio track to be encoded. |
| OH_AVErrCode OH_AudioEncoder_Prepare (OH_AVCodec *codec) | Prepares internal resources for an audio encoder. |
| OH_AVErrCode OH_AudioEncoder_Start (OH_AVCodec *codec) | Starts an audio encoder after it is prepared successfully. |
| OH_AVErrCode OH_AudioEncoder_Stop (OH_AVCodec *codec) | Stops an audio encoder. |
| OH_AVErrCode OH_AudioEncoder_Flush (OH_AVCodec *codec) | Clears the input and output data in the internal buffer of an audio encoder. |
| OH_AVErrCode OH_AudioEncoder_Reset (OH_AVCodec *codec) | Resets an audio encoder. |
| OH_AVFormat * OH_AudioEncoder_GetOutputDescription (OH_AVCodec *codec) | Obtains the description information about the output data of an audio encoder. |
| OH_AVErrCode OH_AudioEncoder_SetParameter (OH_AVCodec *codec, OH_AVFormat *format) | Sets dynamic parameters for an audio encoder. |
| OH_AVErrCode OH_AudioEncoder_PushInputData (OH_AVCodec *codec, uint32_t index, OH_AVCodecBufferAttr attr) | Notifies the audio encoder that the input data has been written to the buffer identified by index. |
| OH_AVErrCode OH_AudioEncoder_FreeOutputData (OH_AVCodec *codec, uint32_t index) | Frees an output buffer of an audio encoder. |
| OH_AVErrCode OH_AudioEncoder_IsValid (OH_AVCodec *codec, bool *isValid) | Checks whether an audio encoder instance is valid. This function is used to check the encoder validity when the background recovers from a fault or an application is switched from the background. |
