Here is a screenshot of a basic usage of peertube-viewer-rs. When launching you are prompted with a search input. Once a search is done, you can either select one of the results by writing the corresponding number or do another search by typing anything else. When you chose to play a video, it will be launched in a video player (mpv by default)
peertube-viewer-rs is a rewrite in rust of peertube-viewer. Though the implementation language doesn't matter for the end user, the name has been changed since breaking changes have been introduced, mainly in the configuration.
