This isn't really an issue, just a problem I had and a fix for it - if someone else encounters it!

TL;DR

Someone at Samsung thought it was a good idea to make the Developer settings UI direction the same as the TV language, resulting with an RTL UI if your TV language is configured to an RTL language (Hebrew, Arabic, etc..)

This means that If you put the IP address in the settings like this:

192	168	1	2

It would result with the actual IP: 2.1.168.192

So in order to put the correct IP address, you need to put:

2	1	168	192

Which would be the correct address: 192.168.1.2

I've tried to install Jellyfin on my Samsung TV but I was unsuccessful, and kept trying for a couple of weeks - but nothing really worked.

No matter what I've tried to do, I wasn't able to connect to my TV - not with Tizen Device Manager, not with sdb.exe, not with this docker image.

Error from Tizen Device Manager:

"error: failed to connect to remote target ..."

Error from sdb.exe:

"failed to connect to ..."

There is no connected target.

Finally today I was able to find the problem, I saw that the docker image is querying the TV model name from some HTTP server on the TV I checked the whole response:

curl -s http://192.168.1.89:8001/api/v2/ | jq

Unrelated things are redacted

There it was, the IP is reversed - I immediately knew this was an RTL issue because I'm used to it so much from other things.

Fix

Either:

Reverse the IP
Change your TV language to English (Recommended)

Georift / install-jellyfin-tizen

RTL layout in developer settings #30
