问题描述
大家好:-)
我正在检查二进制文件。我知道,里面有很多jpeg文件。我想找到这些jpeg文件的字节。
当我查看二进制文件的原始字节时,我发现很多
SOI-marker(Hex D中的FF D8)没有以下JFIF标签(FF E0 00 10 4A 46 49 46 00 01十六进制)。 (但其他人有以下JFIF标签)。
我也看到以下内容:在出现EOI标记之前有许多SOI标记。 (例如:SOI ...... SOI ...... EOI ...... EOI)
我认为这些是jpeg的缩略图,它们位于jpeg本身。
谁能告诉我,这些没有JFIF标签的FF D8是什么意思?
欢迎任何尝试提供帮助: - )
Hi all:-)
I am inspecting a binary file. I know, that there inside are many jpeg-files. I want to find the bytes of these jpeg-files.
When i look at the raw bytes of the binary file, i find many
SOI-marker (FF D8 in Hex) which do not have a following JFIF-tag (FF E0 00 10 4A 46 49 46 00 01 in Hex). (But others have a following JFIF tag).
Also i see the following: There are many SOI-marker before a EOI-marker appears. (eg.: SOI... SOI ... EOI...EOI)
I think that these are thumbnails of the jpeg, which are in the jpeg itself.
Can anyone tell me, what these FF D8 without a following JFIF-tag mean?
Any try to help is welcome:-)
