[solved] Stuttering while watching TV with intel NUC (1 Viewer)

[FaVo]

Hi all,

I have a problem watching live TV since I switched my MediaPortal Client from an AMD APU to an intel NUC. I experience random stuttering while watching live TV and TV recordings. Sometimes there are 20min without any stutter and sometimes they appear in small period. I tried different OS (Win 8.1 (x64), Win 7 (x64 & x86)). Everytime I see that stuttering TV problem.

I use a "MEDION® AKOYA® Mini-PC S2000 D" which is a labeled Intel NUC D54250WYKH with RAM and SSD. So it has plenty of Power as a MediaPortal Client (i5 with intel HD5000).

I'm using a seperate TV Server so the NUC has no USB-Tuner. It is just a client. I do not have this stuttering issues on any other PC or Laptop which I tested as MP Client. I have no clue what causes this stuttering with the Intel NUC.

Can anyone help to get rid of this problem and have an smooth TV experience?

Thanks!

Hi and welcome FaVo,

We're happy to help you, but you need to fill in your system specs and post logs, or else it's simply guessing.
See my signature for the links.

Hi Jeroen,

thanks for your reply. I'm not sure if this is all you need but let's try... I added the System Specs and here is a (hopefully the correct) log file.
There was a stutter a few seconds before I closed the MediaPortal an created the log file. I hope this helps.

Thanks

Hi FaVo,

There are a couple of -A/V buffers in your logs (ran out of buffer) which could have caused the stutter.
There are a few things you can try to improve the playback quality:

Increase the buffer in the registry:
Open regedit.exe
Navigate to HKEY_CURRENT_USER\Software\Team MediaPortal\TsReader
Double click 'BufferingDelayInMilliSeconds' and set a (Decimal) value of 1000

This will increase the buffer with 1000 msec, so expect zapping to be 1 second slower. If 1000 doesn't help, you can increase to (max) 2000 ms.

As an alternative you could try UNC paths instead of RTSP:

Good luck and let us know how the tests go.

Thanks for your support!

So I will try the UNC path thing first and come back later after some tests.

So, first tests are looking good so far... nearly two hours without any flicker/stutter. But that need to be tested over a longer time period.

Edit:
I used the Client for quiet a while now and it seems to be ok now. No more stuttering since I changed to UNC paths. Thanks for your help!

I have no clue why switching to UNC paths should fix that problem but it really seems to be the solution to go. Do you have an explanation why this could reduce/remove the stuttering?

Thanks!

UNC uses a 'direct' link to your timeshift file (see it as playing a local file on your computer), were RTSP is a streaming (network) protocol.
