Summary
Functions
| Name | Description |
|---|---|
| OH_AVCodec * OH_AudioDecoder_CreateByMime (const char *mime) | Creates an audio decoder instance based on a Multipurpose Internet Mail Extension (MIME) type. |
| OH_AVCodec * OH_AudioDecoder_CreateByName (const char *name) | Creates an audio decoder instance based on a decoder name. |
| OH_AVErrCode OH_AudioDecoder_Destroy (OH_AVCodec *codec) | Clears the internal resources of an audio decoder and destroys the decoder instance. |
| OH_AVErrCode OH_AudioDecoder_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 decoder. |
| OH_AVErrCode OH_AudioDecoder_Configure (OH_AVCodec *codec, OH_AVFormat *format) | Configures an audio decoder. Typically, you need to configure the audio description information that can be extracted from the container. |
| OH_AVErrCode OH_AudioDecoder_Prepare (OH_AVCodec *codec) | Prepares internal resources for an audio decoder. |
| OH_AVErrCode OH_AudioDecoder_Start (OH_AVCodec *codec) | Starts an audio decoder after it is prepared successfully. |
| OH_AVErrCode OH_AudioDecoder_Stop (OH_AVCodec *codec) | Stops an audio decoder. |
| OH_AVErrCode OH_AudioDecoder_Flush (OH_AVCodec *codec) | Clears the input and output data in the internal buffer of an audio decoder. |
| OH_AVErrCode OH_AudioDecoder_Reset (OH_AVCodec *codec) | Resets an audio decoder. To continue decoding, you must call Configure to configure the decoder again. |
| OH_AVFormat * OH_AudioDecoder_GetOutputDescription (OH_AVCodec *codec) | Obtains the description information about the output data of an audio decoder. |
| OH_AVErrCode OH_AudioDecoder_SetParameter (OH_AVCodec *codec, OH_AVFormat *format) | Sets dynamic parameters for an audio decoder. |
| OH_AVErrCode OH_AudioDecoder_PushInputData (OH_AVCodec *codec, uint32_t index, OH_AVCodecBufferAttr attr) | Notifies the audio decoder that the input data has been written to the buffer identified by index. |
| OH_AVErrCode OH_AudioDecoder_FreeOutputData (OH_AVCodec *codec, uint32_t index) | Frees an output buffer of an audio decoder. |
| OH_AVErrCode OH_AudioDecoder_IsValid (OH_AVCodec *codec, bool *isValid) | Checks whether an audio decoder instance is valid. This function is used to check the decoder validity when the background recovers from a fault or an application is switched from the background. |
