v1.1.1

[1.1.1] - 2021-12-29

Fixed

• A potential issue with the Lambda for generating thumbnails. Each time a video is uploaded the Lambda downloads the video into /tmp/. However, the Lambda assumed that /tmp/ would be empty each time it is called, which cannot be guaranteed as files from previous invocations can sometimes remain in temp storage. This fix makes the Lambda wipe the /tmp/ folder before processing a new video.
• Minor code refactoring
