<a name="gst-plugins-good-plugins-radioactv.description"></a><h2>Description</h2>
<p>RadioacTV does *NOT* detect a radioactivity. It detects a difference
from previous frame and blurs it.</p>
<p>RadioacTV has 4 mode, normal, strobe1, strobe2 and trigger.
In trigger mode, effect appears only when the trigger property is <a href="/usr/share/gtk-doc/html/glibglib-Standard-Macros.html#TRUE:CAPS"><code class="literal">TRUE</code></a>.</p>
<p>strobe1 and strobe2 mode drops some frames. strobe1 mode uses the difference between
current frame and previous frame dropped, while strobe2 mode uses the difference from
previous frame displayed. The effect of strobe2 is stronger than strobe1.</p>
