Arguments

label	Label for the current page (character scalar).
prompt	Prompt to be displayed above the response choices. Can be either a character scalar (e.g. "What is 2 + 2?") or an object of class "shiny.tag", e.g. shiny::tags$p("What is 2 + 2?").
choices	Character vector of choices for the participant. If unnamed, then these values will be used both for button IDs and for button labels. If named, then values will be used for button IDs and names will be used for button labels.
url	URL to the video. Can be an absolute URL (e.g. "http://mysite.com/video.mp4") or a URL relative to the /www directory (e.g. "video.mp4").
labels	Optional vector of labels for the NAFC choices. If not NULL, will overwrite the names of choices. This vector of labels can either be a character vector or a list of Shiny tag objects, e.g. as created by shiny::HTML().
type	Video type (e.g. 'mp4'). Defaults to the provided file extension.
save_answer	Whether or not to save the answer.
on_complete	Optional function to execute on leaving the page (after successful validation). The argument list should include ..., and any of: state, the participant's state object; answer, the participant's most recent answer; input, the current page's Shiny input object; session, the current Shiny session object; opt, the test's option list as created by test_options().
video_width	Video width, as passed to HTML (e.g. '50px').
arrange_choices_vertically	Whether to arrange the response buttons vertically (the default) as opposed to horizontally.
wait	Whether to wait for the video to finish before displaying the response buttons.
loop	Whether the video should loop.
admin_ui	Optional UI component for the admin panel.
btn_play_prompt	Text to display as a prompt for starting the audio. Ordinarily the participant will not see this, but it might appear if the internet connection is poor, or if the participant refreshes the page. Only used if show_controls is FALSE.
show_controls	Whether or not to show audio controls to the participant, so that they can control audio playback.
allow_download	Whether the participant is given a button to download the audio file; only relevant if show_controls is TRUE.
