title: Vimeo: How to activate captions by default?
body: <p>We have embedded player on our site.<br />
  VTT French captions were been uploaded.</p>
  <p>We need the captions to be activated by default.</p>
  <p>Currently its not happening. The captions are available, <code>CC</code> button is there, and we can switch them ON while playing. But we do want the captions to show automatically.</p>
  <p>The embed code is as follows:<br />
  <code>&lt;iframe class=&quot;embed-responsive-item&quot; src=&quot;https://player.vimeo.com/video/[videoid]?texttrack=fr&quot; frameborder=&quot;0&quot; allow=&quot;autoplay&quot; allowfullscreen&gt;&lt;/iframe&gt;</code></p>
  <p>According to <a href="https://vimeo.zendesk.com/hc/en-us/articles/360027818211-Enabling-Captions-and-Subtitles-in-Embeds-by-Default" rel="nofollow noreferrer">Vimeo' docs</a> <strong>texttrack=fr</strong> is what should make the captions to show automatically.</p>
  <p>The video has language set to <code>English</code>.</p>
  <p>Any idea on how to solve our problem?</p>
