#56 Common path are not recognized

def validateVideo(path):
    path = os.path.normpath(os.path.expanduser(path))
    if not os.path.exists(path):
        logger.error("No file found at path:", path)
        return False

Trying to upload a file containing `~` does not do what is expected: it does not expand to `/home/user`. I am not sure about other tools and other OS. I tried to add the following checks like so (in the end I think this would better be in a specific function). ```py def validateVideo(path): path = os.path.normpath(os.path.expanduser(path)) if not os.path.exists(path): logger.error("No file found at path:", path) return False ``` But doing so also print the backtrace when the log is printed so it is not readable for a standard user. Note: the heart of this code is `path = os.path.expanduser(path)`. This tells python to interpret the path like the shell does.
