Collecting

Keyboard arrow key operations: → (right arrow) Terminate the current episode early; move on to the next episode. ← (left arrow) Cancel the current episode; record it again. ESC, stop immediately, encode the video, and upload the dataset.

After collection is complete, the dataset save directory
