what's the function of the hidden files in MediaPipeTasksCommon/frameworks

[gzhhong]

Hello,

After building the mediapipe framework for ios application by build_ios_framework.sh, there are some hidden files and subfolders in MediaPipeTasksCommon and MediaPipeTasksVision, i.e. in MediaPipeTasksVision or in MediaPipeTasksCommon, the folder structure include:

-rw-r--r--@ 1 zhihong staff 163 2 20 18:57 ._LICENSE
-rwxr-xr-x@ 1 zhihong staff 163 2 20 18:57 ._frameworks
-rw-r--r--@ 1 zhihong staff 12331 2 20 18:57 LICENSE
drwxr-xr-x@ 4 zhihong staff 128 2 20 18:57 frameworks

what's the purpose of the hidden files. When I copy the frameworks MediaPipeTasksVision and MediaPipeTasksCommon to Pods folder of iOS application project. If the hidden files not included, the performance of the frameworks seems not so good.

Regards,

James

Hi @gzhhong,

Could you please specify the hidden files you are referring to? Understanding their purpose will aid our investigation. We will update you after discussing this with our team.

Thank you!!

Hello Kuaashish, after building the ios framework by build_ios_frame.sh, there will be folders like MediaPipeTasksCommon in the target path. Then if you go to the MediaPipeTasksCommon folder and execute 'ls -al', you will find the hidden files like

-rw-r--r--@ 1 zhihong staff 163 2 20 18:57 ._LICENSE
-rwxr-xr-x@ 1 zhihong staff 163 2 20 18:57 ._frameworks

and in the MediaPipeTasksCommon/frameworks folder there are hidden files too, i.e. ls -al MediaPipeTasksCommon/frameworks get the result below:

-rwxr-xr-x@ 1 zhihong staff 163 2 25 18:46 ._MediaPipeTasksCommon.xcframework
-rwxr-xr-x@ 1 zhihong staff 163 2 25 18:46 ._graph_libraries
drwxr-xr-x@ 8 zhihong staff 256 2 25 18:46 MediaPipeTasksCommon.xcframework
drwxr-xr-x@ 6 zhihong staff 192 2 25 18:46 graph_libraries

If the developer copy the folder MediaPipeTasksCommon to the Pods folder of iOS application (i.e. hand landmarker), the hidden files will be missed. But the iOS application can still work, but the MediaPipe library seems not work in good performance, the jitter on landmarks is more than the application with library including the hidden files.
