</div>As Denis already pointed out, a dedicated input thread will be required, with<br>
its own demuxer and video decoder instances. It wouldn't be the trivial matter<br>
of inserting a video filter in the existing playlist input thread: such a filter<br>
can only access pictures just before they are output.<br>
<br>
With a dedicated input, there are at least three different ways to model it:<br>
1/ a stream output plugin,<br>
2/ a video filter with the dummy video output behind it,<br>
3/ a video output.<br>
But with just that, you will need to decode the whole video track. as<br>
explained by Denis.<br>

<br>
</div>There is the image_handler, maybe. But that's the least of concerns, I think.<br>

<br>
</div>That belongs in the component that will control your dedicated input. That<br>
does not really fit in any existing abstraction.<br>
<br>
<br>
That being said, where is this feature provided currently? I somehow suspect<br>
that it is normally being precomputed offline and passed to the media player as<br>
some meta-data associated with the media file.<br>
