The video file ./assets/apple.mp4 could be potentially corrupted

Hello,
Thank you for your great work.
I was trying to run to the gradle demo and attempted to try on the apple video located under assets, which could not be loaded.When attempting to do local playback, it did not play at all.
Please check it out.

Start by running the Gradle demo and attempting local playback of assets/apple.mp4, then inspect whether the repository copy is readable. Done means determining whether the asset is corrupted and documenting or addressing the reproducible playback failure.
