New Windows 11 Emby Installation - Live TV Quality Issues

[bwlonsdale 0]

So my current setup(s):-

Emby version on all of these setups is 4.8.10.0

QNAP NAS 653D - Live TV, via my HDHomeRun is fine - Live TV quality is good, no breakup. All clients are OK (either by browser, Win 11 Emby client)

New Windows 11 Install - Live TV, via same HDHomeRun is abysmal - breaking up, pixellation, aspect ratio is ignored.

Native HDHomeRun App running on Windows 11 on another PC - Live TV Quality is good, no breakup.

i.e. there's no issue with the tuner hardware, or signal strength.

So where to start troubleshooting this, please? Do I need some other codecs installed on the new Win 11 install, I assumed FFMPEG handled the decode side of things?

I've tried turning Allow Hardware Transcoding on and off, makes no difference, that's pretty much the only option available.

Logs attached where Live TV was breaking up.

This fixed it - had RDP open while I was messing with stuff....doh.

Browser based Live TV still won't stick to the correct aspect ratio for some reason. None of the available options are 16:9, Emby Win App is fine still.

And none of the above display correctly.

This is affecting live TV SD channel broadcasts in a browser (Stats say it's 578i) - screenshots from Firefox - this is BBC One as an example, aspect ratio should be 16:9 - what I see happening is the aspect ratio starts out correctly for a few seconds, then it get jumps into squished ratio, which looks like 4:3. The option is on Auto. If I try Cover or Fill, then it does change the picture, but not for the better (see caps)

I am using  a 34" monitor monitor (3440 x 1440), same behaviour across Firefox, Edge and Chrome.

If I switch to a HD broadcast (1080i), it works fine - stays on correct aspect ratio.

SD TV content is normally 4:3, unless authored as widescreen, so unless you are manipulating the image it should look like the above picture which is 4:3 with black bars on the sides.
If you want it to use the full screen you could have your Emby client either stretch the image or zoom the image.

Carlo, please refrain from commenting on this. You clearly haven't got a clue what you're talking about.

OK we'll take a look at this. Thanks.

@Lukedo you see anything wrong here? The only thing IMHO that's wrong is the stretched videos distorting the aspect ratio.
The second two pictures are not displayed with a proper aspect ratio of 16:9, as they are stretched horizontally.
16:9 content displayed on a 21:9 aspect ratio (3440x1440) ultrawide monitor will use 76.2% (16/21) of the screen width, with roughly 24% of screen as black bars on the sides. 16:9 content displayed on a 34-inch (21:9) monitor should appear as if you're watching a 26-inch (16:9) monitor.

Aside from the distorted aspect ratio, the first picture of the SD content looks correct to me if the Display Aspect Ratio (DAR) was 4:3. However, if the DAR was 16:9, there should be approximately 4 inches of black bars on each side of the video. Assuming the resolution was 720x576i it could have a DAR of 4:3 or 16:9, but I've not seen Chrome or Edge get this wrong, hence my initial post saying it looks right to me (assuming 4:3 DAR).

Hi, we'll take a look at it. Thanks for reporting.
