perf(local): avoid duplicate parsing of VideoThumbPos (#7812)

Browse Source 
* feat(local): support percent for video thumbnail

The percentage determines the point in the video (as a percentage of the total duration) at which the thumbnail will be generated.

* feat(local): support both time and percent for video thumbnail

* refactor(local): avoid duplicate parsing of VideoThumbPos
