Request: Implement video trimming feature in editor playback

[destin55]

Am trying to implement an instance where a clip's start_time and end_time should affect its playback duration.
The clip should only play from its provided start_time and complete at its provided end_time even if the start time is more than 0 and the end time is less than the actual duration of the clip.

Can anyone guide me how i would successfully achieve that. Am only currently focusing on the playback and not export.
