Wrong video orientation

[Opi]

Subject: 0.93: Videos taken in portrait mode play in 180° orientation

XnView: MP 0.93.1 - 64 bit
OS: Windows 10 64bit


Actual behaviour: Videos taken in portrait mode with smartphones (tested with huawei p20 and xiaomi mi 9t) in mp4 container with h.264 codec have an rotation tag. XnView MP seems to read this tag, but turns the video in the wrong direction. If I play the same videos in VLC Player it's right.

The Problem is also described for the classic version of XnViev viewtopic.php?t=38328.
In the Classic version the orientation is ignored completely.

The same with IPhone Videos

Because nobody cares about it, the problem still exists in year 2021 in version 0.98.
Same procedure as in year 2019, I uninstalled the software and use Darktable instead.

Please try to use installed codec

Code: Select all

useInternalVideoPlayer=false

When I make that change many of my phone camera mpg and mov videos refuse to play.

do you have installed codecs like 'Klite codec pack'?

No, I had bad experiences with such packages years ago and avoid them.
