Is seems like video is rotated but display resolution is not.

To me the web client looks like it is stretching the video.  Looking at those two images I would think the TV is correct 270degree image from like a phone.

Yes that one shows the opposite to me.  But will have to wait on one of the Samsung gurus to comment.

I think I can see why it is displaying it wrong, but as @Happy2Play has commented, something seems backwards. 
 

Since that looks like a short video, could you please share a copy of it with me via PM and I will see if I can work out what we need to do to make this display correctly.

The issue with this video is that it has a rotation set in the metadata, so players like vlc and modern browsers adjust the aspect ratio based on this rotation flag.

https://blog.addpipe.com/mp4-rotation-metadata-in-mobile-video-files/

22:40:51.129     Stream #0:1(eng): Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, smpte170m/bt470bg/smpte170m), 1080x1920, 12983 kb/s, SAR 1:1 DAR 9:16, Level 40, 30.09 fps, 90k tbr, 90k tbn, 180k tbc (default)
22:40:51.129     Metadata:
22:40:51.129       rotate          : 270
22:40:51.129       creation_time   : 2019-09-07T09:39:01.000000Z
22:40:51.129       handler_name    : VideoHandle
22:40:51.129     Side data:
22:40:51.129       displaymatrix: rotation of 90.00 degrees

In the Tizen app we don't see this rotation flag, so the rotation to the aspect ratio (9:16 -> 16:9) is not being applied.

To correct this, we would need the rotate metadata.  @Luke?  Does this sound correct?  I don't think there's any other way to handle this

I'm working on something that will help in the short term.  Hopefully in the next usb release.

I have the same issue. Aspect ratio of files is fine using DLNA but videos are stretched to fill the whole t.v. screen when using emby app, so app specific. Will await the USB release!

This sounds like a different issue.  Could you please post the mediainfo for a file?

Please can you give me steps on how to obtain it? It seems to be all the videos I've taken with my phone (Samsung s7)

Just copy and paste the media info section from the bottom of the web app detail screen.

Okay - got it!

I notice when I play via the webapp, with the settings dial on the right, its on Auto aspect ratio, and it plays fine (black on either side of video)

On the TV, its like its in "fill" mode.

So this should be display as portrait, (tall and narrow) instead of landscape.  Correct?

@Luke, is it possible to bring in the rotation parameter as part of the stream probe, or is that not likely to happen?  The issue is that these items have a rotation angle, and the html video player rotates the aspect ratio automatically based on this angle, but in the Tizen avplayer we will need to rotate this manually.   For the original case, adding the Fill option will resolve this as the video needs to go from portrait to landscape, but this example I suspect needs to go the other way, which is not so easy without the rotate angle

 Yes, it should - you are correct!

Just to confirm, the video itself is oriented correctly, in terms of that I took it in a portrait manner, but when its being played via emby, the video is being stretched/filled to the whole screen.

Thanks for confirming.  You are correct, the video is the right orientation, but the aspect ratio needs to rotate from 20:11 to 11:20.  Do do this, we need to know that it has a rotation factor.

Alright, we'll leave it in yours and the teams capable hands!

On a positive note, its only my second day of using emby and I'm very pleased with it otherwise! :)

@Eselter Can you please try the latest USB release?  It isn't resolved, but from the playback settings menu you can now change the Aspect ratio to Fill which will expand the video to full screen.  If you have the basic remote (not the smart remote) you can also press the Pic.Size button to toggle this.

It's not a complete solution, but should help for now.

Fill whole screen working fine but this only works fine with horizontal video with the same aspect ratio like TV.

The biggest problem now is vertical video witch is displaying horizontal on TV (instant of 9:16 is 16:9) and this solution don't help in this case.

Can you please attach a photo showing showing this?  Does it just need resizing, or does it need to be rotated as well?
