<p>The current setup is:</p>

<pre><code>   ______________
  | Computer     |
  |______________|
 DVI |        | HDMI
     |        |
HDMI |        | HDMI
  ___|____   _|_________
 | Video  | | 2560x1080 |
 |Streamer| | monitor   |
 |________| |___________|
 eth |
</code></pre>

<p>So, basically I just have an ultrawide monitor running at 2560x1080 connected to a PC. I also want to stream a clone of what is displayed on that ultrawide monitor so I can see what's happening over LAN. I use an external streaming hardware box (Antrica brand) for that, and have no problems using resolutions lower than 2560x1080.</p>

<p>The problem is that my streaming hardware (and many other external video hardware) supports only resolutions up to 1920x1080. </p>

<p>So I need to downscale, resize and/or crop the cloned video output of the computer which goes to the streamer. This leads to my actual question: how to do that?</p>

<p>Ideally, there would be some kind of a hardware video downscaler box between the computer and streamer. The box should accept 2560x1080 input. Even more ideally I would have an option to choose whether to downscale or crop the inputted video. Do such boxes exist? Or are there other ways to achieve this?</p>

Does it have to be a hardware solution? ffmpeg could do this in software.

Preferably yes, because I want to avoid performance impacts of software solutions. However, I could try this out. Could you please help me getting started in doing this with ffmpeg?
