I have a flexdashboard that has a runtime of shiny. I’m looking to allow the user to select an input and for an associated mp4 file to play. All videos are stored within the working directory of the .Rmd file. The current code I have identifies theres a video to play but cant play. In the inspect element selection I get the following error: Failed to load resource: the server responded with a status of 404 (Not Found)
