鸿蒙系统ijk开源播放器

# ijkplayer ## 简介 > ijkplayer是OpenHarmony环境下可用的一款基于FFmpeg的视频播放器。 ## 演示 <img src="screenshot/ijkplayer-zh.gif" width="100%"/> ## 编译运行 1、通过IDE工具下载依赖SDK，Tools->SDK Manager->OpenHarmony SDK 把native选项勾上下载，API版本>=9 2、开发板选择RK3568，[ROM下载地址](http://ci.openharmony.cn/workbench/cicd/dailybuild/dailylist). 选择开发板类型是rk3568，请使用最新的版本 3、使用git clone下载源码，不要直接通过gitee网页的方式下载 ## 下载安装 ```shell ohpm install @ohos/ijkplayer ``` ## 使用说明 ``` import { IjkMediaPlayer } from "@ohos/ijkplayer"; import type { OnPreparedListener } from "@ohos/ijkplayer"; import type { OnVideoSizeChangedListener } from "@ohos/ijkplayer"; import type { OnCompletionListener } from "@ohos/ijkplayer"; import type { OnBufferingUpdateListener } from "@ohos/ijkplayer"; import type { OnErrorListener } from "@ohos/ijkplayer"; import type { OnInfoListener } from "@ohos/ijkplayer"; import type { OnSeekCompleteListener } from "@ohos/ijkplayer"; import { LogUtils } from "@ohos/ijkplayer"; ``` ### 在UI中配置XComponent控件 ``` XComponent({ id: 'xcomponentId', type: 'surface', libraryname: 'ijkplayer_napi' }) .onLoad((context) => { this.initDelayPlay(context); }) .onDestroy(() => { }) .width('100%') .aspectRatio(this.aspRatio) ``` ### 播放 ``` let mIjkMediaPlayer = IjkMediaPlayer.getInstance(); // 设置XComponent回调的context mIjkMediaPlayer.setContext(this.mContext); // 设置debug模式 mIjkMediaPlayer.setDebug(true); // 初始化配置 mIjkMediaPlayer.native_setup(); // 设置视频源 mIjkMediaPlayer.setDataSource(url); // 设置视频源http请求头 let headers = new Map([ ["user_agent", "Mozilla/5.0 BiliDroid/7.30.0 (bbcallen@gmail.com)"], ["referer", "https://www.bilibili.com"] ]); mIjkMediaPlayer.setDataSourceHeader(headers); // 使用精确寻帧 例如，拖动播放后，会寻找最近的关键帧进行播放，很有可能关键帧的位置不是拖动后的位置，而是较前的位置.可以设置这个参数来解决问题 mIjkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "enable-accurate-seek", "1"); // 预读数据的缓冲区大小 mIjkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "max-buffer-size", "102400"); // 停止预读的最小帧数 mIjkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "min-frames", "100"); // 启动预加载 mIjkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "start-on-prepared", "1"); // 设置无缓冲，这是播放器的缓冲区，有数据就播放 mIjkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "packet-buffering", "0"); // 跳帧处理,放CPU处理较慢时，进行跳帧处理，保证播放流程，画面和声音同步 mIjkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "framedrop", "5"); // 最大缓冲cache是3s， 有时候网络波动，会突然在短时间内收到好几秒的数据 // 因此需要播放器丢包，才不会累积延时 // 这个和第三个参数packet-buffering无关。 mIjkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "max_cached_duration", "3000"); // 无限制收流 mIjkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "infbuf", "1"); // 屏幕常亮 mIjkMediaPlayer.setScreenOnWhilePlaying(true); // 设置超时 mIjkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_FORMAT, "timeout", "10000000");

} } mIjkMediaPlayer.setOnErrorListener(mOnErrorListener); mIjkMediaPlayer.setMessageListener(); mIjkMediaPlayer.prepareAsync(); mIjkMediaPlayer.start(); ``` ### 暂停 ``` mIjkMediaPlayer.pause(); ``` ### 停止 ``` mIjkMediaPlayer.stop(); ``` ### 重置 ``` mIjkMediaPlayer.reset(); ``` ### 释放 ``` mIjkMediaPlayer.release(); ``` ### 快进、后退 ``` mIjkMediaPlayer.seekTo(msec); ``` ### 倍数播放 ``` mIjkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "soundtouch", "1"); mIjkMediaPlayer.setSpeed("2f"); ``` ### 屏幕常亮 ``` mIjkMediaPlayer.setScreenOnWhilePlaying(true); ``` ### 循环播放 ``` mIjkMediaPlayer.setLoopCount(true); ``` ### 设置音量 ``` mIjkMediaPlayer.setVolume(leftVolume, rightVolume);
