In the Twitter Player Card implementation
-
The video thumbnail is not showing. This was done as
meta(name=“twitter:image”, content="#{videoThumb}")
and video html5 poster in the iframe share intent:
video(width='720', height='1280', src='#{videoStreamingUrl}', poster="#{videoThumb}", type='video/mp4')
Note. Look at the player icon, it seems it has been rotated of -90°.
