XnView Software

Fixed in 1.3

Fixed in 1.3

We'll keep an eye for bugs, new SDKs tend to be unstable.

QtAV has not been maintained since January. Are there plans to switch to a different library?

The EXIF is not at fault since every other player displays the videos with the correct orientation.
This is an XnView bug.

Yup

XnView comes with some icons for common file types in C:\Program Files\XnViewMP\FileIcons

However, some file types like .svg and .ico are missing. Where can I find icons for those types?

Version 0.99.7 64bits (Jan 13 2022)
Bug still exists, workaround does not work.

XnView MP uses a component based on ffmpeg, and there is no way to manage orientation.

ffmpeg can definitely do a 180 degrees rotation of a video (or a combination of vertical and horizontal flips, which give the same end result).
See for example https://superuser.com/questions/578321/how-to ...

It's been almost 3 years since the problem has been reported. It happens both in XnView classic and Xnview MP, but not in VLC, Media Player, or any other player I tried.

What makes it so difficult to fix?

It's been over two years since this issue was reported (see viewtopic.php?f=62&t=37840).

Here's a screenshot:

When I tried it, videos stopped displaying at all. I got the controls but the video display area was blank.

Yes, apologies.

Note, this also happens on Xnview MP 0.98.4
