LGTM, but needs a rebase due to resolve the conflict caused by your other PR. I currently lost track of all the contributions that are part of courses at universities. Please let me know if you are an ANU student for internal statistics and because I am writing my master thesis about open source contributions as part of learning computer science and computer science education at university. |

Description of the changes in your PR
Youtubes api seems to have VERY rarely "broken" preview storyboards i.e. storyboards that are too small for the given amount of frames on the x axis and width of frames. In the linked issue only the width seems to be affected but i assume the same could happen to the height.
As an example for this video https://www.youtube.com/watch?v=sxl4DJXCDzA (jumpscare/loud sound warning) the api returns this storyboard https://i.ytimg.com/sb/sxl4DJXCDzA/storyboard3_L2/M0.jpg?sqp=-oaymwENSDfyq4qpAwVwAcABBqLzl_8DBgiPyu6jBg==&sigh=rs$AOn4CLD0HwvNS2nXMr9JYlzeuRbC1ubbtg which should have 5 160 pixel wide frames (which is 800 pixels). The image is only 795 pixels wide so it breaks at some point when trying to create a bitmap for the preview.
For this video https://www.youtube.com/watch?v=CH50zuS8DD0 the storyboard is correctly sized: https://i.ytimg.com/sb/CH50zuS8DD0/storyboard3_L2/M0.jpg?sqp=-oaymwENSDfyq4qpAwVwAcABBqLzl_8DBgikqp23Bg==&sigh=rs$AOn4CLBG_KgXP0R2Z1DI9hg-Ntn7xCnrXA.
Seems to be a youtube sided thing, i don't see any issues on the extractor side (but I could be wrong about that of course). The only "solution" i found was to catch these cases and "manually" and adjust the bounds of the preview, even though i am not super happy with that approach. There seems to be no pattern (same video length for example) behind this behaviour but this statement comes with a very small sample size so I might have missed something.
