KTVHTTPCache

KTVHTTPCache is a powerful media cache framework. It can cache HTTP request, and very suitable for media resources. 感谢开源 , 此版本兼容m3u8视频缓存

  • 添加对m3u8的支持 请使用此方法
  • 支持同局域网 airplay
    __weak ViewController * weakself = self;
    [KTVHTTPCache proxyURLWithOriginalURL:item.URLString complete:^(NSURL *url) {
        
        NSLog(@"absoluteString === %@",url.absoluteString);
        MediaViewController *vc = [[MediaViewController alloc] initWithURLString:url.absoluteString];
        [weakself presentViewController:vc animated:YES completion:nil];
    }];

下载m3u8视频 的脚本

# 预下载，获取m3u8文件，读出ts链接，并写入文档

  # m3u8链接
  url = m3u8Url
  # 当ts文件链接不完整时，需拼凑
  # 大部分网站可使用该方法拼接，部分特殊网站需单独拼接

  # print(base_url)

      # 一定要先写文件，因为线程的下载是无序的，文件无法按照
      # 123456。。。去顺序排序，而文件中的命名也无法保证是按顺序的
      # 这会导致下载的ts文件无序，合并时，就会顺序错误，导致视频有问题。

Usage

  • Start proxy.
[KTVHTTPCache proxyStart:&error];
  • Generated proxy URL.
NSURL *proxyURL = [KTVHTTPCache proxyURLWithOriginalURL:originalURL];
AVPlayer *player = [AVPlayer playerWithURL:proxyURL];
  • Get the complete cache file URL if existed.
NSURL *completeCacheFileURL= [KTVHTTPCache cacheCompleteFileURLWithURL:originalURL];
  • Set the URL filter processing mapping relationship.
[KTVHTTPCache encodeSetURLConverter:^NSURL *(NSURL *URL) {
    return URL;
}];
  • Download Configuration
// Timeout interval.
[KTVHTTPCache downloadSetTimeoutInterval:30];

// Accept Content-Type.
[KTVHTTPCache downloadSetAcceptableContentTypes:contentTypes];

// Set unsupport Content-Type filter.
[KTVHTTPCache downloadSetUnacceptableContentTypeDisposer:^BOOL(NSURL *URL, NSString *contentType) {
    return NO;
}];

// Additional headers.
[KTVHTTPCache downloadSetAdditionalHeaders:headers];

// Whitelist headers.
[KTVHTTPCache downloadSetWhitelistHeaderKeys:headers];
  • Log.
// Console.
[KTVHTTPCache logSetConsoleLogEnable:YES];

// File.
[KTVHTTPCache logSetRecordLogEnable:YES];
