this.catchMedia []; this.mediaSize 0; // 代理MediaSource方法 this.proxyMediaSourceMethods(); // 监控XMLHttpRequest和Fetch API this.interceptNetworkRequests(); } proxyMediaSourceMethods() { // 重写MediaSource的addSourceBuffer方法 const originalAddSourceBuffer MediaSource.prototype.addSourceBuffer; MediaSource.prototype.addSourceBuffer function(mimeType) { const sourceBuffer originalAddSourceBuffer.call(this, mimeType); // 监控sourceBuffer的appendBuffer操作 this.monitorSourceBuffer(sourceBuffer); return sourceBuffer; }; } }流媒体解析技术对于HLSm3u8和DASHmpd等流媒体协议猫抓内置专门的解析器。js/m3u8.js文件实现了完整的m3u8解析逻辑// m3u8解析核心逻辑 function parseM3U8(content, url) { const lines content.split(\n); const result { version: null, targetDuration: null, mediaSequence: 0, segments: [], key: null, iv: null }; for (let i 0; i lines.length; i) { const line lines[i].trim(); if (line.startsWith(#EXT-X-VERSION:)) { result.version parseInt(line.split(:)[1]); } else if (line.startsWith(#EXT-X-TARGETDURATION:)) { result.targetDuration parseInt(line.split(:)[1]); } else if (line.startsWith(#EXT-X-KEY:)) { result.key parseKey(line); } else if (line.startsWith(#EXT-X-MEDIA-SEQUENCE:)) { result.mediaSequence parseInt(line.split(:)[1]); } else if (line.startsWith(#EXTINF:)) { const duration parseFloat(line.split(:)[1].split(,)[0]); const segmentUrl lines[i 1].trim(); if (segmentUrl !segmentUrl.startsWith(#)) { result.segments.push({ duration: duration, url: new URL(segmentUrl, url).href }); } } } return result; }图2猫抓m3u8解析器界面支持TS分片下载、解密和合并功能配置实践7个高效工作流方案方案1智能过滤规则配置通过js/options.js中的配置系统用户可以自定义资源过滤规则。以下是高级过滤配置示例// 自定义扩展名过滤 const extFilters { video: { ext: [.mp4, .m4v, .mov, .avi, .mkv, .flv, .webm], operator: include, size: 10MB }, audio: { ext: [.mp3, .wav, .aac, .flac, .ogg], operator: include, size: 1MB }, image: { ext: [.jpg, .jpeg, .png, .gif, .webp], operator: exclude, size: 500KB } };
