You can use this page to visualize the behavior of the
playlist switcher under different network conditions. It
can helpful to understand how tweaks to the switching
logic will affect playback.

Flash security restrictions prevent this page from running

<h2>Parameters</h2>
<form id=parameters>
<ol class=network-timeline>
<li>
<label>
After <input name=time0 class=time type=number value=0 min=0> seconds,
</label>
<label>
the link capacity is <input name=bandwidth0 class=bandwidth type=number value=921600> bits per second
</label>
</li>
<li>
<label>
After <input name=time1 class=time type=number value=150 min=0> seconds,
</label>
<label>
the link capacity is <input name=bandwidth1 class=bandwidth type=number value=450560> bits per second
</label>
</li>
<li>
<label>
After <input name=time2 class=time type=number value=600 min=0> seconds,
</label>
<label>
the link capacity is <input name=bandwidth2 class=bandwidth type=number value=1843200> bits per second
</label>
</li>
</ol>
<p>
You can simulate more complex network conditions by
changing the bandwidth during the run. Start a new time
period and then define its starting time and link
capacity.
<button type=button class=add-time-period>Add time period</button>
</p>
<p>
If you've created a complex scenario you'd like to retry
later, run the simulation and then save the URL of this
page. All of the network conditions you specify are
saved into the URL fragment after the results of a
simulation run are displayed.
