Maybe related: MPEG2 video plays in 4:3 even though set to 16:9. Goes for both DVD-folders and MKV-remux.

Aspect ratio appears to be a recent addition, (last 1 or 2 releases) and I suspect it's never worked on LG.

 

@@hanand, have you seen anything movies that it works on?

 

@@Luke, i suspect that fit and cover have no effect on this platform

I assume that video file was cropped to remove black bars, and this wouldn't happen with a straight BD rip?

Yes, a lot of people and we're not able to reproduce the problem. That's why we're asking you to provide a sample video for testing. Is that possible?

I just ran into this issue with one specific file which plays correctly as 4:3 on my phone and on the web but is stretched to 16:9 on my LG TV.

It has a "Display Aspect Ratio" and "Original Display Aspect Ratio" though, and I'm not sure how to get rid of that. When I first went to watch it I assumed a bad aspect ratio flag so I remuxed it and had "Set aspect ratio" at "4/3", but that didn't work.

A similar problem has been observed in this post https://emby.media/community/index.php?/topic/43525-all-files-with-the-original-display-aspect-ratio-tag-play-at-wrong-resolution/

 

This probably explains it best : https://sourceforge.net/p/mediainfo/discussion/297610/thread/5c5de6d2/

 

From this, my interpretation is that there is a mismatch between the aspect ratio defined in the video stream compared to the container.

 

DAR is what is specified in the container

ODAR is what is specified in the original stream.

 

Normally if these are the same (they should be) then only one value DAR is reported.  When they are different, there is really a problem with the file

 

Actually, this problem should never happen. raw stream DAR should be always Container DAR. There is no reason to display 2 lines, simply because in theory container DAR is a copy, exact copy, of raw stream DAR.

So I display 2 values only when they are different, to warn the user there is a potential problem.

 

Some players will preference the DAR from the container, while others will use the DAR from the stream.  I expect this is why you are seeing a difference on different devices.

 

The question is why is the stream aspect ratio 16:9?
