Hi Sami32,
sorry, of course . . .
Logs are attached now. I also found out, that some other 4k-files doesn´t work at all.

Hi Callahan,

Make FFmpeg video engine as your first choice engine. Using MEncoder, old and poorly maintened, will only give you problem.

From the "Transcoding settings" tab select "FFmpeg" and deselect "Defer to MEncoder when transcoding problematic issue".
You can set "MEncoder" as your third choice video files engines or disabled it if you prefer.

If you still get issue, don't forget to join your new trace log.

Hi Sami32,

I did the changes you recommend but I didn´t change the behaviour.
I found one sample-movie which is working but ´some other are stuttering and the most are not working at all.
Log is attached.

Hi callahan,

That's normal, as you use a not appropriate renderer, though i think that something else occur.

Try this renderer, as it will give you less transcoding issues: (delete the .txt extension)

Samsung-UHD.conf.txt

(4.26 KiB) Downloaded 1279 times

To avoid the stuttering with the transcoded files, you can add some parameters, or to avoid videos having unsupported audio TrueHD/DTS-HD (MA or 8 channels) or subtitles (PGS...though you can disable them or use external supported ones instead).
Try to add these parameters in the Mencoder video files engines custom option found into "Transcoding settings" tab:

Code: Select all

-vf scale=1920:1080

And select "Remux videos with tsMuxeR when possible instead of transcoding".

That way, you'll see correctly the supported videos with FFmpeg by default, and the one stuttering should be tried with MEncoder engine, and hopefully give you some playing improvements.

Please, take time to return feedback
Don't forget to join a new log if you report some issues.

P.S. As a side note, you can delete this line

Code: Select all

fix_25fps_av_mismatch=true

from your UMS.conf file, except if you really need it of course.

EDIT: You can try to delete the MEncoder custom parameters already set, and select the "Skip loop filter deblocking for H.264" option.

But all the settings hasn´t changed anything
Same behaviour as before. Maybe I am too stupid . . . .

I cannot find this line in UMS.conf file . . . (?)

EDIT: You can try to delete the MEncoder custom parameters already set, and select the "Skip loop filter deblocking for H.264" option.

done, but seemes to be without effect . . .

Hello callahan,

Code: Select all

fix_25fps_av_mismatch=true

is in your UMS.conf, not the one inside your UniversalMediaServer program folder but inside the one in the Documents and Settings\All Users\UMS folder.
You can also edit it from UMS GUI, in the "General Configuration" tab select "Edit UMS configuration file manually" and go to the end of the file.

I updated the renderer:

Samsung-UHD.conf

Though your issue seem to be a bandwidth or/and CPU issue.
Could you confirm that [2160p] 4K-HD.Club-2013-Taipei 101 Fireworks Trailer (4ksamples.com).mp4 is stuttering while streamed from UMS ?
And that your movies are playing fine from a USB or HDD ?

For testing purpose only, set the maximum bandwidth in the "General Configuration" tab to 30 MB/s, and if any improvements occur try to increase this value until you get stuttering. The stuttering increase or decrease should fix us.

If it's a CPU power resource issue, as i suspect, i'm afraid that your choice will resume to decrease the video dimensions or the video quality. You already know how to change the 2 dimensions value in your renderer configuration, so if you absolutely want see your movies in UHD with this computer the FFmpeg customs parameters should be set accordingly.

Hi,

I have now new TV Samsung UE65KS9002T and I still have problems with playing x265 mkv files..
for test I have try: (I also have original Blu Ray)
The Revenant (2015) 4K UltraHD BluRay HEVC x265 DTS-HD 7.1 [Zeus-n-Duke].mkv
but I have get error and offer me to skip this file...

please for helping me out and tell me which config do I have to use that I could see that kind of files...

best regards to all

[Sami32]

Hi alesk76,

you should try that renderer.

Edit the file and uncomment these lines:

Code: Select all

#MaxVideoWidth = 3840
#MaxVideoHeight = 2160

And modify this line as following:

Code: Select all

H264Level41Limited = false

If you still get issue, just click on the red link in my signature and read the 3 first comments.
