I’m saying is that one should have the ability to turn on/off a poster.
Currently once the poster has been made invisible by the UA, there is no way to
turn it back on. So if I wanted to turn it back on after the video has ended, I
can’t and I think people should have that choice?</span></p>

This makes sense, we should spec this so that the poster <i>must</i> be visible
until its played, otherwise the poster attribute can't be relied upon by
authors.<br>

<p class="MsoNormal"><br>
Aesthetically, I feel we shouldn't show the poster once the video has finished.
Authors could script this behaviour if they wanted it. The spec as it's written
forbids showing the poster after a video frame has been shown.<br>

<pre> </pre><pre>I don't see why this is necessary.</pre>
<p class="MsoNormal"><br>
I also don't see why this is necessary. The poster attribute is only useful if
it's enabled, it's not useful if it isn't. Having an attribute to denote
whether the poster attribute is enabled seems like duplication of state to me.<br>

<pre> </pre><pre>to restore, if you like. (In browsers that implement dataset, which</pre><pre>is apparently only WebKit so far. But you can easily store the</pre><pre>original value someplace else, although not quite as elegantly.)</pre>

<p class="MsoNormal"><br>
The specification for poster [1] implies that we should handle dynamic changes
to the poster attribute. I can imagine authors may want to cycle through a
chain of poster images for a given video, and this can (theoretically) be
easily implemented by changing the poster attribute in a timer.<br>
