Summary
Structs
| Name | Description |
|---|---|
| OH_AVCodecBufferAttr | Defines the buffer attributes of an OH_AVCodec instance. |
| OH_AVCodecAsyncCallback | Defines a collection of asynchronous callback functions for an OH_AVCodec instance. You must register this struct instance for an OH_AVCodec instance and process the information reported through these callbacks to ensure the normal running of the instance. |
Types
| Name | Description |
|---|---|
| OH_AVCodecBufferFlags | Enumerates the buffer flags of an OH_AVCodec instance. |
| OH_AVCodecBufferAttr | Defines the buffer attributes of an OH_AVCodec instance. |
| OH_AVCodecOnError) (OH_AVCodec *codec, int32_t errorCode, void *userData) | Defines the function pointer that is called to report error information when an error occurs during the running of an OH_AVCodec instance. |
| OH_AVCodecOnStreamChanged) (OH_AVCodec *codec, OH_AVFormat *format, void *userData) | Defines the function pointer that is called to report the attributes of the new stream when the output stream changes. Note that the lifecycle of the pointer to the OH_AVFormat instance is valid only when the function pointer is being called. Do not access the pointer to the instance after the function pointer is called. |
| OH_AVCodecOnNeedInputData) (OH_AVCodec *codec, uint32_t index, OH_AVMemory *data, void *userData) | Defines the function pointer that is called, with a new buffer to fill in new input data, when new input data is required during the running of an OH_AVCodec instance. |
| OH_AVCodecOnNewOutputData) (OH_AVCodec *codec, uint32_t index, OH_AVMemory *data, OH_AVCodecBufferAttr *attr, void *userData) | Defines the function pointer that is called, with a buffer containing new output data, when the new output data is generated during the running of an OH_AVCodec instance. Note that the lifecycle of the pointer to the OH_AVCodecBufferAttr instance is valid only when the function pointer is being called. Do not access the pointer to the instance after the function pointer is called. |
| OH_AVCodecAsyncCallback | Defines a collection of asynchronous callback functions for an OH_AVCodec instance. You must register this struct instance for an OH_AVCodec instance and process the information reported through these callbacks to ensure the normal running of the instance. |
| OH_MediaType | Enumerates the media types. |
| OH_AVCProfile | Enumerates the AVC profiles. |
| OH_AACProfile | Enumerates the AAC profiles. |
