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/c...ong-resolution/

 

This probably explains it best : https://sourceforge....hread/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?

That, I do not know.  Is it just this file that has a problem?

 

You could try mkvmerge or ffmpeg to fix it https://superuser.co...ing-video-fileĀ

Remuxing it doesn't work, in either MkvToolNix or ffmpeg.

Whan you say remuxing, you will need to do more than move it to a new container.  You will have to try and change the aspect ratio on the video stream to 4:3 to match the container

It may not be possible to fix it without re-encoding the whole stream somehow

I have an OLED55C6V (2016) in the UK and an LED32610V (2017) and parents have 43UM6750PLA (2019)and aspect ratios are fine on 1.0.24 with H264 and MPEG2 content, if the content is encoded with correct flags (DAR).

 

So its not across all LG TVs, I suspect encoding of the material and its flags for aspect. What is it like on another LG or Samsung or ROKU or Web Player? Is the video shown incorrectly on those too?

Right, I have had two videos now were anamorphic flags were set and they play at 16:9 on everything BAR the LG player so I have changed my view to the original poster.

 

99.9% of the time the LG gets it right (they are all encoded in the same high level 4.0 interlaced video), but there are one or two and it ignores it and displays 4:3. I don't get the vertical stretching like the original poster showed, as the video is happily displayed at 4:3 or 16:9, I just prefer the 16:9 view.

movies 4k HDR are not in the right aspect ratio.

 

Hi, Can you please take a photo of what you see, and attach the server logs and provide the full MediaInfo for that item?  Thanks.

 

Can you please check that your TV settings are correct
