- public
- Privilege:
- http://tizen.org/privilege/mediastorage
- Privilege:
- http://tizen.org/privilege/externalstorage
- Remarks:
- If you want to access only internal storage by using this function, you should add privilege http://tizen.org/privilege/mediastorage.
Or if you want to access only external storage by using this function, you should add privilege http://tizen.org/privilege/externalstorage.
If you want to access both storage, you must add both privileges.
- Parameters:
-
[in] editor The media editor handle [in] path The content location to add [in] layer_id The layer ID to add clip [in] start The starting position of path clip which is placed in timeline (in milliseconds)
If this is less than 0, clip will be added to the end of layer. i.e. it will be set to layer's duration[in] duration The duration that the clip is in effect for in the timeline (in milliseconds)
It should be lesser than or equal to clip's duration. If not, error will be occurred in runtime.
The clip should have enough internal content greater than duration.[in] in_point The initial offset of path clip to use internally when outputting content (in milliseconds) [out] clip_id The ID of added clip. It'll be used when you want to delete this clip.
