关于获取章节信息

zdw19840929 commented 3 months ago

大佬，问一个问题，我看log里面打印是有章节信息的，如果有的话是在IJKFFMoviePlayerController里面的traverseIJKMetaData这个方法里面解析吗？

已经实现了，调用：

NSArray *chapteArr = self.player.monitor.chapterMetaArr;
NSLog(@"video chapters:%@",chapteArr);

结果

video chapters:(
        {
        end = 60000;
        id = 0;
        start = 0;
        title = "Chapter 1";
    },
        {
        end = 120000;
        id = 1;
        start = 60000;
        title = "Chapter 2";
    },
        {
        end = 150000;
        id = 2;
        start = 120000;
        title = "Chapter 3";
    }
)

代码将会在下个版本发布。
