Overlaying alpha images on a video using ffmpeg
<p>I have the following ffmpeg-cli command which does not produce the described effect in documentation. Could this be a bug, or I have something wrong with the command. </p>

<pre><code>ffmpeg \
    -y \
    -i small.mp4 \
    -i monkey/monkey_%04d.png \
    -filter_complex "[0:v][1:v]overlay=enable='between(t,1,5)'[out1]" \
    -map '[out1]' \
    output.mp4
</code></pre>

<p>I expect it to overlay the #1 stream on top of #0 between seconds 1 and 5.</p>

<p>You may download the test tarball from this link:</p>

</ul>

<p>It includes assets for the test case.</p>

<p>The build I tried with:</p>

<ul>
<li>ffmpeg-3.0.2-64bit-static (available online)</li>
</ul>
