Summary
Functions
| Name | Description |
|---|---|
| OH_AVCodec * OH_AudioCodec_CreateByMime (const char *mime, bool isEncoder) | Creates an audio codec instance based on a Multipurpose Internet Mail Extension (MIME) type. |
| OH_AVCodec * OH_AudioCodec_CreateByName (const char *name) | Creates an audio codec instance based on a codec name. |
| OH_AVErrCode OH_AudioCodec_Destroy (OH_AVCodec *codec) | Clears the internal resources of an audio codec and destroys the codec instance. |
| OH_AVErrCode OH_AudioCodec_RegisterCallback (OH_AVCodec *codec, OH_AVCodecCallback callback, void *userData) | Sets an asynchronous callback so that your application can respond to events generated by an audio codec. This function must be called prior to Prepare. |
| OH_AVErrCode OH_AudioCodec_Configure (OH_AVCodec *codec, const OH_AVFormat *format) | Configures the audio description. The audio codec is usually configured based on the audio description. |
| OH_AVErrCode OH_AudioCodec_Prepare (OH_AVCodec *codec) | Prepares internal resources for an audio codec. |
| OH_AVErrCode OH_AudioCodec_Start (OH_AVCodec *codec) | Starts an audio codec after it is prepared successfully. |
| OH_AVErrCode OH_AudioCodec_Stop (OH_AVCodec *codec) | Stops an audio codec. |
| OH_AVErrCode OH_AudioCodec_Flush (OH_AVCodec *codec) | Clears the input and output data in the internal buffer of an audio codec. |
| OH_AVErrCode OH_AudioCodec_Reset (OH_AVCodec *codec) | Resets an audio codec. The configured parameters and input and output data are cleared. To continue encoding or decoding, you must call Configure to configure the codec again. |
| OH_AVFormat * OH_AudioCodec_GetOutputDescription (OH_AVCodec *codec) | Obtains the description information about the output data of an audio codec. |
| OH_AVErrCode OH_AudioCodec_SetParameter (OH_AVCodec *codec, const OH_AVFormat *format) | Sets dynamic parameters for an audio codec. |
| OH_AVErrCode OH_AudioCodec_PushInputBuffer (OH_AVCodec *codec, uint32_t index) | Notifies the audio codec that the input data has been written to the buffer identified by index. |
| OH_AVErrCode OH_AudioCodec_FreeOutputBuffer (OH_AVCodec *codec, uint32_t index) | Frees an output buffer of an audio codec. |
| OH_AVErrCode OH_AudioCodec_IsValid (OH_AVCodec *codec, bool *isValid) | Checks whether an audio codec instance is valid. This function is used to detect the codec status when a background fault is rectified or an application is switched from the background. |
| OH_AVErrCode OH_AudioCodec_SetDecryptionConfig (OH_AVCodec *codec, MediaKeySession *mediaKeySession, bool secureAudio) | Sets the decryption information. |
