Kolor Eyes Desktop - Video decoding

Video decoding

You can change video plugin through the category « Video Plugin » in the menu.

By default, Kolor Eyes will choose the best default video plugin according to your OS and if you are using an Oculus or not. Default video plugins according to OS are listed here.

Changing the video plugin will directly affect Kolor Eyes video decoding abilities. Kolor Eyes will use a different video backend according to this setting. Available backends will depends on the platform.


Change video plugin



Windows

There are three video backends available on Windows platform : VLC, WMF (Windows Media Foundation) and DirectShow.

Use of Directshow is deprecated but we still allow you to use it.


VLC

This backend uses libVLC to decode video. You should never encounter errors with backend.

VLC on Windows does not support video hardware decoding by default for now and so high resolutions, as 4K, can be jerky.
Hardware decoding allows to decode a video more efficiently than software decoding. So on the same computer, hardware decoding gives the opportunity to have a smooth video playback when software decoding failed (jerky playback).

Note : when using Oculus Rift on Windows, we are forced to use OpenGL graphics framework and so we loose hardware decoding with WMF. That is why VLC is the default when using Oculus Rift on Windows.

You can enable/disable hardware video decoding by moving the cursor


WMF

It is the default video backend of Windows, it means that if Windows Media Player can't read a video Kolor Eyes can't too.

Note that Windows 8 has native codecs which decode 4K video and so Kolor Eyes will be able to decode 4K video without installing any codec on Windows 8. It is not the same for Windows 7 (or previous Windows versions) which do not have native codecs to decode 4K video.


DirectShow

You will need to have codecs that use DirectShow filters like MainConcept codecs. If you have Autopano Video installed on your machine you also have MainConcept codecs installed.



Mac

There are three video backends available on Mac platform : VLC, AVF and Quick Time 7.


VLC

This backend uses libVLC to decode video. You should never encounter errors with backend.

VLC on Mac supports video hardware decoding and so it gives the best video performances.
Hardware decoding allows to decode a video more efficiently than software decoding. So on the same computer, hardware decoding gives the opportunity to have a smooth video playback when software decoding failed (jerky playback).

You can enable/disable hardware video decoding by moving the cursor


AVF

It is the default video backend of Mac, it means that if Quick Time Player can't read a video Kolor Eyes can't too.

We recommend you to use AVF because this backend allows Kolor Eyes to use video hardware decoding and so it gives the best video performances.


Quick Time 7

Legacy video backend of Mac.

Image decoding

You can use Kolor Eyes to visualize your 360 pano whatever the pano size.

If the pano is too large, it will be downsized according to your graphic card capabilities.
