Since: 11
Related module: AVPlayer
Summary
Structs
| Name | Description |
|---|---|
| struct AVPlayerCallback | (Deprecated) Contains the set of the OH_AVPlayerOnInfo and OH_AVPlayerOnInfo callback function pointers. To ensure the normal running of OH_AVPlayer, you must register the instance of this struct with the OH_AVPlayer instance and process the information reported by the callback functions. |
Types
| Name | Description |
|---|---|
| typedef enum AVPlayerState AVPlayerState | Defines an enum for the AVPlayer states. |
| typedef enum AVPlayerSeekMode AVPlayerSeekMode | Defines an enum for the seek modes of the AVPlayer. |
| typedef enum AVPlaybackSpeed AVPlaybackSpeed | Defines an enum for the playback speeds of the AVPlayer. |
| typedef enum AVPlayerOnInfoType AVPlayerOnInfoType | Defines an enum for the types of messages received by the AVPlayer. |
| typedef enum AVPlayerBufferingType AVPlayerBufferingType | Defines the types of buffer messages of the AVPlayer. |
| typedef void(* OH_AVPlayerOnInfo) (OH_AVPlayer *player, AVPlayerOnInfoType type, int32_t extra) | (Deprecated) Defines the callback invoked when the AVPlayer receives a message. |
| typedef void(* OH_AVPlayerOnInfoCallback) (OH_AVPlayer *player, AVPlayerOnInfoType type, OH_AVFormat *infoBody, void *userData) | Defines the callback invoked when the AVPlayer receives a message. If this callback is successfully set, the OH_AVPlayerOnInfo function will not be invoked. |
| typedef void(* OH_AVPlayerOnError) (OH_AVPlayer *player, int32_t errorCode, const char *errorMsg) | (Deprecated) Defines the callback invoked when an error occurs in the AVPlayer. This type is available in API version 9 or later. |
| typedef void(* OH_AVPlayerOnErrorCallback) (OH_AVPlayer *player, int32_t errorCode, const char *errorMsg, void *userData) | Defines the callback invoked when an error occurs in the AVPlayer. If this callback is successfully set, the OH_AVPlayerOnError function will not be invoked. |
| typedef struct AVPlayerCallback AVPlayerCallback | Defines all the callback function pointers of an OH_AVPlayer instance. |
