adtf dat文件-流和结构类型 [英] Adtf dat files - streams and structure types
问题描述
ADTF dat文件包含数据流.在.dat文件中，只有一个流名称.要找到流的结构，必须先通过DDL .description文件.
ADTF dat file contains streams of data. In the .dat file there is only a stream name. To find the structure of the stream one has to go through DDL .description file.
有时.description文件不完整或缺少从流名称到相应结构的链接.
Sometimes the .description files are incomplete or are missing link from stream name to corresponding structure.
.dat文件本身中隐藏了一些有关结构名称的附加信息吗? (或者我的理解是完全错误的?)
Is there some additional information about structure name hidden in the .dat file itself? (Or my understanding is completely wrong?)
推荐答案
ADTF 2.x和ADTF 3.x及其(adtf)dat文件结构之间必须有所区别.
You must differ between ADTF 2.x and ADTF 3.x and their (adtf)dat file structure.
ADTF 2.x:
是的，您只能使用ddl解释数据.流必须指向媒体描述中描述的结构.
You are right, you can only interpret data with ddl. The stream must point to a structure described in Media Description.
有时.description文件不完整或缺少链接 从流名称到相应的结构.
Sometimes the .description files are incomplete or are missing link from stream name to corresponding structure.
您可以通过在硬盘记录器中启用选项创建媒体描述来避免这种情况.然后，*.dat.description将存储在同名的* .dat文件旁边，该文件包含正确的流和结构引用，因为它在记录期间可用.
You can avoid this by enable the Option Create Media Description in Harddisk Recorder. Then a *.dat.description will be stored next to the same-titled *.dat file, which contains the correct stream and structure reference, because it was available during recording.
.dat文件本身中是否隐藏有一些有关结构名称的其他信息?
Is there some additional information about structure name hidden in the .dat file itself?
否，它只是流名称.因此，您需要了解背后的数据结构进行解释.如果您有标头(c-struct)，则还可以转换为ddl并进行引用.
No, it is only the stream name. So you need to know the data structure behind to interpret. If you have the header (c-struct), you can also convert to ddl and refer to that.
ADTF 3.x:
为避免不可用或不正确的描述文件而出现这些问题，DDL现在存储在ADTF 3.x的* .adtfdat文件中
To avoid these problems for not available or incorrect description files, the DDL is now stored in the *.adtfdat file in ADTF 3.x
