title: LibVLC: Is a filter like v360:fisheye from ffmpeg available in LibVLC?
body: <p>I'm having problem playing fisheye(180) videos panoramically on the fly
  using LibVlcSharp in a WinForms appliction.</p>
  <p>More specifically: what I want to do is filtering video with libvlcsharp in a WinForms application(c#) with the same effect like</p>
  <pre><code>-vf v360=fisheye:e:ih_fov=180:iv_fov=180:pitch=90
  </code></pre>
  <p>from ffmpeg.</p>
  <p>FYI: this will not make the video tagged with equirectanglar projection, the v360=fisheye filter dewarps the video and the video stays rectanglar.</p>
  <p>The input video is like this:</p>
  <p><a href="https://i.stack.imgur.com/4vzCa.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/4vzCa.jpg" alt="enter image description here" /></a></p>
  <p>And the the expected output should be like:</p>
  <p><a href="https://i.stack.imgur.com/DO9KC.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/DO9KC.jpg" alt="output video" /></a></p>
  <p>This can be achieved by:</p>
  <pre><code>./ffmpeg -i input.mov  -vf v360=fisheye:e:ih_fov=180:iv_fov=180:pitch=90,crop=in_w:in_h/2:in_w:in_h/2 output.mov
  </code></pre>
  <p>but I need to do this with LibVLC and on the fly.</p>
  <p>Can I achieve this with LibVLC's video filter?</p>
  <p>Or I need to develop my own filter and make a wrapper for c#?</p>
