KJBasePlayerView播放器视图基类，播放器控件父类

/* 长按手势反馈 */
- (void)kj_basePlayerView:(KJBasePlayerView*)view longPress:(UILongPressGestureRecognizer*)longPress;

/* 亮度手势反馈，是否替换自带UI，范围0 ～ 1 */
- (BOOL)kj_basePlayerView:(KJBasePlayerView*)view brightnessValue:(float)value;

KJPlayerType

枚举文件夹和公共方法管理

  • KJPlayerState：播放器状态
  • KJPlayerCustomCode：错误code
  • KJPlayerGestureType：手势操作
  • KJPlayerPlayType：播放类型
  • KJPlayerDeviceDirection：手机方向
  • KJPlayerVideoGravity：播放器充满类型
  • KJPlayerVideoFromat：视频格式

DBPlayerDataInfo

主要包括两部分，数据库模型和增删改查等工具
数据库结构

dbid：唯一id，视频链接去除scheme然后md5
videoUrl：视频链接  
saveTime：存储时间戳
sandboxPath：沙盒地址
videoFormat：视频格式
videoTime：视频时间
videoData：视频数据

数据库工具

方法 功能
kj_insertData:Data: 插入数据，重复数据替换处理
kj_deleteData: 删除数据
kj_addData: 新添加数据
kj_updateData:Data: 更新数据
kj_checkData: 查询数据，传空传全部数据
kCheckAppointDatas 指定条件查询

KJResourceLoader

中间桥梁作用，把网络请求缓存到本地的临时数据传递给播放器

KJPlayer - AVPlayer播放器内核

工作流程：
1、获取视频类型，根据网址来确定，目前没找到更好的方式（知道的朋友可以指点一下）

/// 根据链接获取Asset类型
NS_INLINE KJPlayerAssetType kPlayerVideoAesstType(NSURL *url){
    if (url == nil) return KJPlayerAssetTypeNONE;
    if (url.pathExtension.length) {
        if ([url.pathExtension containsString:@"m3u8"] || [url.pathExtension containsString:@"ts"]) {
            return KJPlayerAssetTypeHLS;
        }
    }
    NSArray * array = [url.path componentsSeparatedByString:@"."];
    if (array.count == 0) {
        return KJPlayerAssetTypeNONE;
    }else{
        if ([array.lastObject containsString:@"m3u8"] || [array.lastObject containsString:@"ts"]) {
            return KJPlayerAssetTypeHLS;
        }
    }
    return KJPlayerAssetTypeFILE;
}

2、处理视频，这里才用队列组来处理，子线程处理解决第一次加载卡顿问题

dispatch_group_async(group, dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
    if ([weakself kj_dealVideoURL:&tempURL]) {
        if (![tempURL.absoluteString isEqualToString:self->_videoURL.absoluteString]) {
            self->_videoURL = tempURL;
            [weakself kj_initPreparePlayer];
        }else{
            [weakself kj_playerReplay];
        }
    }
});

3、处理视频链接地址，这里分两种情况，使用缓存就从缓存当中读取

/* 判断当前资源文件是否有缓存，修改为指定链接地址 */
- (void)kj_judgeHaveCacheWithVideoURL:(NSURL * _Nonnull __strong * _Nonnull)videoURL{
    self.locality = NO;
    KJCacheManager.kJudgeHaveCacheURL(^(BOOL locality) {
        self.locality = locality;
        if (locality) {
            self.playError = [DBPlayerDataInfo kj_errorSummarizing:KJPlayerCustomCodeCachedComplete];
        }
    }, videoURL);
}

获取数据库当中的数据

/* 判断是否有缓存，返回缓存链接 */
+ (void(^)(void(^)(BOOL),NSURL * _Nonnull __strong * _Nonnull))kJudgeHaveCacheURL{
    return ^(void(^locality)(BOOL),NSURL * _Nonnull __strong * _Nonnull videoURL){
        NSArray<DBPlayerData*>*temps = [DBPlayerDataInfo kj_checkData:kPlayerIntactName(*videoURL)];
        BOOL boo = NO;
        if (temps.count) {
            DBPlayerData *data = temps.firstObject;
            NSString *path = data.sandboxPath;
            if (data.videoIntact && [KJCacheManager kj_haveFileSandboxPath:&path]) {
                //移出之前的临时文件
                NSString *tempPath = [path stringByAppendingPathExtension:kTempReadName];
                [[NSFileManager defaultManager] removeItemAtPath:tempPath error:NULL];
                *videoURL = [NSURL fileURLWithPath:path];
                boo = YES;
            }
        }
        kGCD_player_main(^{
            if (locality) locality(boo);
        });
    };
}

4、判断地址是否可用，添加下载和播放桥梁

PLAYER_WEAKSELF;
if (!kPlayerHaveTracks(*videoURL, ^(AVURLAsset * asset) {
    if (weakself.useCacheFunction && !weakself.localityData) {
        weakself.state = KJPlayerStateBuffering;
        weakself.loadState = KJPlayerLoadStateNone;
        NSURL * tempURL = weakself.connection.kj_createSchemeURL(*videoURL);
        weakself.asset = [AVURLAsset URLAssetWithURL:tempURL options:weakself.requestHeader];
        [weakself.asset.resourceLoader setDelegate:weakself.connection queue:dispatch_get_main_queue()];
    }else{
        weakself.asset = asset;
    }
}, self.requestHeader)) {
    self.ecode = KJPlayerCustomCodeVideoURLFault;
    self.state = KJPlayerStateFailed;
    [self kj_destroyPlayer];
    return NO;
}

5、播放准备操作设置playerItem，然后初始化player，添加时间观察者处理播放

self.timeObserver = [self.player addPeriodicTimeObserverForInterval:CMTimeMakeWithSeconds(_timeSpace, NSEC_PER_SEC) queue:dispatch_queue_create("kj.player.time.queue", NULL) usingBlock:^(CMTime time) {
    NSTimeInterval sec = CMTimeGetSeconds(time);
    if (isnan(sec) || sec < 0) sec = 0;
    if (weakself.totalTime <= 0) return;
    if ((NSInteger)sec >= (NSInteger)weakself.totalTime) {
        [weakself.player pause];
        weakself.state = KJPlayerStatePlayFinished;
        weakself.currentTime = 0;
    }else if (weakself.userPause == NO && weakself.buffered) {
        weakself.state = KJPlayerStatePlaying;
        weakself.currentTime = sec;
    }
    if (sec > weakself.tryTime && weakself.tryTime) {
        [weakself kj_pause];
        if (!weakself.tryLooked) {
            weakself.tryLooked = YES;
            kGCD_player_main(^{
                if (weakself.tryTimeBlock) weakself.tryTimeBlock();
            });
        }
    }else{
        weakself.tryLooked = NO;
    }
}];

6、处理视频状态，kvo监听播放器五种状态

  • status：监听播放器状态
  • loadedTimeRanges：监听播放器缓冲进度
  • presentationSize：监听视频尺寸
  • playbackBufferEmpty：监听缓存不够的情况
  • playbackLikelyToKeepUp：监听缓存足够

大致流程就差不多这样子，Demo也写的很详细，可以自己去看看
