Samsung SmartTV. Playback interrupts and lags

Is it all files, or just this one that has the issue?

yesterday it was "Aladdin" (corresponding log attached)

early there were another files. it's hard to point to the one file.

You mean TV reset, not restart - yes, go ahead.

Did you try this?

Did you try a different WiFi channel? Any way that you can test with a cabled connection, even a temporary test?

as I said earlier, now I practice pre-rebooting TV, but sometimes my family members watch TV and they don't know about pre-rebooting.

yes, yesterday Aladdin was watched after the channel change.

There is no option to make TV wired. now I'm searching the web to purchase good quality wi-fi to ethernet bridge to exclude internal Wi-Fi chip.

Just remember that the LAN port is only 100Mbit so doesn't need to be too good.

I use one of these and have no issues with up to 80Mb/s files on my 2017 Samsung TV.

how fast does it boots up? I've got VONETS bridge that need about 120 seconds to boot. USB port in my Samsung TV is not always on so every time TV starts without network and I need to wait about 2 minutes before I can use Emby or anything else that needs network connectivity.

Good idea! Like SAmES wrote.

We're not guessing, it's your network or your media or your TV.  You need to work out which one it is by trial and error.

As I wrote previously: It could be also only the TV that have an issue with the connexion even if your network works fine. Especially if it just happens to this one TV.

Try LAN port before if possible.

I leave it on all the time, doesn't use much power.

Back to your files, for Aladdin, does it always stop at the same places? Is it ever possible to watch it without any issues? For example, if you reboot the TV, can you then play it all the way without issues, or does Aladdin always have an issue?  I'm trying to understand if it could possibly be a file/compatibility issue?

no, it doesn't - it's always random. I'll make clean test.

sure! my wife loves this movie and watched it through Plex many-many times before .

It could be also

the Sun radiation, UFO first contact, the Moon altitude, neighborhood's EMI, fallback to 2.4Ghz and microwave oven, enemy's spy diversion, and a hundred assumptions more.

we are at the second round of one and the same questions

since the DLNA client always works well, I'm betting on software problems, not on hardware. but..... "this is the different"

well, okay.

I think you should understand that the purpose of this forum is to find a solution together. We're trying to see what the possibilities are for your technical problem. I'm sorry if we can't figure it out right away; apparently, it's not easy in your case. Please note that my only purpose in responding to your messages was to try to help you. And the other members do the same.

My suggestion in the last post was to connect your tv by the LAN cable to avoid use the Wifi. It can be a step to check if the problem comes from the network. So, your tv does not have any LAN port?

According to your screenshot, you have a Samsung model 
https://www.samsung.com/ph/tvs/uhd-4k-tv/au7002-50-inch-uhd-4k-smart-tv-ua50au7002gxxp
It should have a LAN port. So, you can check if using the cable you will have the same problem.

I do understand that and I appreciate your help. but I want to note that many questions are asked in a circle over and over again, although detailed answers are already in this topic. An example is above.

my experience is based on the method of working through the exclusion of factors and subsequent diagnostics of those that could not be excluded.
now my position is that the problem exists specifically in this TV (I have three more and none of them have ever had such problems), but this problem is extremely unlikely to be related to Wi-Fi, because DLNA as a technology completely excludes this. it does not exclude software and a decoder inside, but it excludes the network as transport. I do not mind connecting a cable and not even checking, but proving it, but at the same time I ask for something more than another option "you have bad Wi-Fi"

[SamES 1057]

We're just trying to get clear, definite answers to the problem. If we are asking the same question, it is because your answers are unclear or contradictory, and remember that we are helping many people with issues on multiple platforms and can't remember (or re-read) every issue and its details.

Based on your recent tests, the problem is your TV or your network.

First question, can you 100% confirm that your TV does not have a LAN port.  I find that hard to believe.

Make sure your TV has the latest firmware, and I would recommend a factory reset to ensure everything is clear and reset.

I can confirm that my TV does have a LAN port, but I have no ability to extend the cable to it, what's why I/m searching and testing Wi-Fi bridges. Vonets VAR1200-L has several issues described above and was excluded of the test, now I'm waiting for TP-link TL-WR1502X and Keenetic Buddy 6. I'm not sure which Ethernet port in the TV FE or GE, but even 100mbps is enough for me - I have only one Movie with 94mbps bitrate and the next is 75mbps.

Are you sure? That's a monstrous bitrate. If anyone else on your network does anything at all, I'm pretty sure both of you will instantly experience lag.

Did you setup your Emby app to use the local ip-adress of your server or do you connect via a domain name / remote ip-address?

why do you think so? my router has MIMO 4x4 antennas and 100mbps  throughput per client is not so hard for it.

during stress test with iperf3 (Intel NIC wired PC as a server and Intel NIC wireless laptop as a client) I've got up to 300mbps UDP flow with only <3% loss.

@WingDogyou're making a lot of assumptions about what should work, but the fact is that something isn't working and we need to test these things via trial and error. Unless your server is underpowered or overloaded, I'm still certain from your feedback that you have a network or a TV issue.

Do you have one or two Samsung TV's with this model number? UE50AU7002UXRU - In the log it looks like there are two.  Do they both have this issue?

Did you check and try this?

Yesterday you provided this logfile and said Aladdin used to work and now it's not, but do you realise that it was not DirectPlay?

sure. I was sure that DirectPlay does not use any significant server resources, but since you say so, I'm ready to provide any additional data. Will the Windows perfmon counters be enough or do you need something else? If it is enough, then specify which ones you want to see.

I have only one TV with model number UE50AU7002UXRU. others are another Samsung (will check model later) and noname Chinese TV (TF-LED24S80T2S).

I checked the latest firmware and will try factory reset today. In addition tomorrow I'll got Keenetic wi-fi bridge and will try it too.

I can see the same TV with 2 different IP's.  One is failing, so it's not valid, but at some stage your TV had a different IP.  Are you using DHCP and maybe your TV keeps getting different addresses.  Maybe try a hardcoded IP for a test.

Let's just start with server specs (RAM, CPU, general setup details)

I suppose that was an Vonets bridge IP address.

I completely agree with user brothom's comment. Even if you have a perfect network, streaming this movie at this bitrate seems like an impossible mission (bitrate 94, 4k, 10 bit). 67 Gb: I suppose it's an original Blu-ray. 

SamES, probably, starting with the server specs in order to take a look around it's a good step. 

[SamES 1057]

What is this?  What is it for, what are its specs? Immediately it makes me suspicious.

I suggest we agree that I am an insane user who collects movies that he can't watch.
Forget about Snatch, it has nothing to do with the problem with DirectPlay from the first post, nor with playing Aladdin through a transcoder.

you have no cause to be suspicious - I told you about that wi-fi bridge yesterday and you advised me TP-Link. this device is already off.

anyway, there is nothing to think about at all - if I had connected the LAN interface, the IP address would have also changed, because the MAC addresses of the Wi-Fi chip and the wired chip are different.
