libwlmedia

跨平台播放器wlmedia现在已经支持了鸿蒙(Harmony)平台了，SDK插件地址：libwlmedia

一、接入SDK

1.1 导入SDK

ohpm i @ywl5320/libwlmedia

1.2 添加权限（可选）

如果需要播放网络视频，需要添加网络权限

#module.json5
"requestPermissions": [{"name": "ohos.permission.INTERNET"}
]

1.3 设置XComponentController

let wlPlayer: WlPlayer = new WlPlayer();
let wlComponentController: WlComponentController = new WlComponentController(this.wlPlayer);
...
XComponent({type: XComponentType.SURFACE,controller: this.wlComponentController}).width('100%').height('100%')
...

1.4 基础调用代码

@Entry
@Component
struct Index{private wlPlayer: WlPlayer | null = null;private wlComponentController: WlComponentController | null = null;aboutToAppear(): void {this.wlPlayer = new WlPlayer();this.wlPlayer.setOnMediaInfoListener({onPrepared: (): void => {// 异步准备好后回调，这里调用 wlplayer.start() 开始播放this.wlPlayer?.start();},onTimeInfo: (currentTime: number, bufferTime: number): void => {// 时间进度回调 },onComplete: (wlCompleteType: WlCompleteType, msg: string): void => {if (wlCompleteType == WlCompleteType.WL_COMPLETE_EOF) {// 正常播放完成} else if (wlCompleteType == WlCompleteType.WL_COMPLETE_ERROR) {// 播放出错，原因为：msg 字段} else if (wlCompleteType == WlCompleteType.WL_COMPLETE_HANDLE) {// 主动调用 wlPlayer.stop() 会回调此类型} else if (wlCompleteType == WlCompleteType.WL_COMPLETE_NEXT) {// 正在播放中，切换了新的数据源，会回调此类型} else if (wlCompleteType == WlCompleteType.WL_COMPLETE_TIMEOUT) {// 播放超时，会回调此接口} else if (wlCompleteType == WlCompleteType.WL_COMPLETE_LOOP) {// 循环播放中，每开始新的一次循环，会回调此接口}},onLoadInfo: (loadStatus: WlLoadStatus, progress: number, speed: number): void => {// 加载状态回调if (wlLoadStatus == WlLoadStatus.WL_LOADING_STATUS_START) {// 开始加载} else if (wlLoadStatus == WlLoadStatus.WL_LOADING_STATUS_PROGRESS) {// 加载进度} else if (wlLoadStatus == WlLoadStatus.WL_LOADING_STATUS_FINISH) {// 加载完成}},onFirstFrameRendered: (): void => {// seek 完成回调},onSeekFinish: (): void => {// seek 完成回调},onAudioInterrupt: (type: WlAudioInterruptType, hint: WlAudioInterruptHint) => {// 音频打断，和系统一致}this.wlComponentController = new WlComponentController(this.wlPlayer);this.wlPlayer.setClearLastVideoFrame(this.wlComponentController.getUniqueNum(), false);}// 退出 销毁资源onBackPress(): boolean | void {this.wlPlayer?.release()}build() {Column() {XComponent({type: XComponentType.SURFACE,controller: this.wlComponentController}).onLoad((event) => {// 加载完成后就开始播放this.wlPlayer?.setSource(this.filesDir + "/huoying_cut.mkv");this.wlPlayer?.prepare();}).width('100%').height('100%')}}
}

二、效果展示

三、注意事项

• 模拟器播放需要设置解码类型为soft，因为模拟器测试不支持硬解码。

this.wlPlayer.setCodecType(WlCodecType.WL_CODEC_SOFT)

四、更多功能
