VTCLab Media Analyzer — 支持的文件头
以下是本解析器支持的全部容器格式、视频编解码器、音频编解码器和字幕格式。点击带有详细数据的格式，即可查看逐元素的解析详情。
每个元素都带有标签，用于标示本系统的支持级别。共有 5 个级别：
| 不支持 | 即解析器不会显示该元素内的任何属性，甚至可能根本不识别该元素 | |
| 部分支持 | 解析器会识别该元素，并显示其中部分属性，但并非全部 | |
| 支持，无说明 | 解析器会显示元素的所有属性，但仅以数值形式呈现 | |
| 支持，含部分说明 | 解析器会以数值形式显示元素的所有属性，并为部分字段附加文字说明。 例如，MPEG-TS Program Map Table 中 'stream_type' 字段的数值 '4' 会附带文字 'ISO/IEC 13818-3 Audio' | |
| 支持，含完整说明 | 对于标准定义了额外释义的属性，会按对应的释义形式显示 |
如果发现您关注的某个元素尚未完全支持，或者根本没有列出，欢迎发邮件至 analyzer@vtclab.com （在新标签页打开），或在我们的 GitHub 仓库 （在新标签页打开） 中提交 issue。
