XnViewMP 0.92: portrait videos playing upside down
XnView: MP 0.92
OS: Windows 10 1803 64bit
KLite Mega Codec Pack 14.6.0
XnViewMP plays portrait videos upside down both on the preview an on the built-in player. Works fine with MPC-HC. Happens to multiple files. XnViewMP was installed from scratch.

Thanks for your help,

The issue of video playing upside down is still continuing.
Is there any possibility of a fix being issued ?

Re: XnViewMP 0.92: portrait videos playing upside down
If you record a movie with your camera or smartphone, an orientation information is saved within the movie file (rotation information).
Standard video player (VLC, mpc player, etc.) can use on the fly rotation, to fix the problem.
There are a few video tools, which can change the orientation/rotation information within the video file.
Sometimes it works, on some it does not work.
Try to look on google to find such a tool. I think ffmpeg can do the job.

Re: XnViewMP 0.92: portrait videos playing upside down
This issue for me is on Windows (latest build) anyway.
The thumbnails don't match either. But I guess that would involve reading the metadata info and slow things down a bit.
I think it's the way XnView reads the metadata of the rotation.
See the screenshot where I've corrected it for XnView but in all other programs, the rotation is wrong.
If I revert the file back to work in File Explorer Preview or PotPlayer, then XnView is wrong.
I can only assume that FileExplorer and PotPlayer are both correct.

Re: XnViewMP 0.92: portrait videos playing upside down
Why don't you use the latest XnviewMP 0.98.4 version?
It contains the latest video decoder/filters!
I tested some mp4 video files from smartphone (Samsung S10) and with XnViewMP 0.98.4 the playback is fine!
A few thumbnails are upside down the same way you decribed and do not use the correct orientation information from the video file.

Re: XnViewMP 0.92: portrait videos playing upside down
I'm using that version.
Re: XnViewMP 0.92: portrait videos playing upside down
In this forum somebody changed the video file orientation information with the exiftool.

Re: XnViewMP 0.92: portrait videos playing upside down
Tried that. It didn't have any effect.
All players as I stated in the first post I tried playing, played the video correctly. XnViewMp did not.

Re: XnViewMP 0.92: portrait videos playing upside down
I confirm a bug in xnviewmp with rotation value in exif. Using Linux.
I tested different rotations via exiftool. You can try it with:
exiftool -Rotation=0 file.mp4
exiftool -Rotation=90 file.mp4
exiftool -Rotation=180 file.mp4
exiftool -Rotation=270 file.mp4
Result is: Rotation=0 and Rotation=180 work correctly in xnviewmp. But 90 and 270 are interpreted inverted in xnviewmp. e.g 90 rotates left instead of right. And 270 rotates right instead of left.
That's definitely a bug.

Re: XnViewMP 0.92: portrait videos playing upside down
It's been over two years since this issue was reported (see viewtopic.php?f=62&t=37840).
[ Edit: almost three years: viewtopic.php?t=38328 ]
What makes it so difficult to fix?

Re: XnViewMP 0.92: portrait videos playing upside down
XnView MP uses a component based on ffmpeg, and there is no way to manage orientation. You can try the system player by editing your xnview.ini
useInternalVideoPlayer=false
