Hi,

I have a Samsung JS7200 and I have created a configuration file based on http://www.samsung.com/us/support/answer/ANS00049184/

I am however unable to playback some videos, In the logs attached I have issues with 2 videos:
- Central Intelligence (3840x2160)
- Doctor Strange (1920x800)

The tests were run on UMS 6.6.0 running headless on Ubuntu 16.04.. Included in the attachment is:
- Samsung-JS7200.conf
- UMS.conf
- debug.log with log_level = TRACE
- mediainfo and mkvinfo on the 2 files.

Any help/direction would be appreciated.

Thanks,

Hi,

What do you mean by unable to playback ?
These movies need to be transcoded by UMS, and as far as i saw in your log it do it.

Try to unselect "Prettify filenames..." and test if you saw any playback difference on them.

Hi,

Unsetting Prettify filenames makes no difference.

When I say unable to playback, I mean I am getting an error on the TV.

I should point out that the majority of mkv files work without any issues although a subset are giving me this error.

Thanks :+1:
I'll look more deeply at your log later.

That weird though...

For now you can try to set your maximum bandwith to 60Mb/s.
And if it doesn't make things better try adding this line into your renderer configuration file:

Code: Select all

DefaultVBVBufSize = true

Hi,

I've limited the maximum bandwidth and set the DefaultVBVBufSize to no avail. The error still occurs.

Hi,

I've not had an issue with other older files. I seem to have issues with the newer files (circa past 3 months or so), and especially with 4K files.

Create the video manually with this command, and play it from a USB/HDD plugged in your TV.

Code: Select all

/home/ums-user/ums-6.6.0/linux/ffmpeg64 -i "/data/ums-user/Media/English/Doctor Strange (2016).mkv" -map 0:v -map 0:a:0 -bufsize 1000000k -maxrate 999000k -crf 19 -ac 6 -ab 640k -ar 48000 -c:a ac3 -c:v libx264 -tune zerolatency -preset ultrafast -level 31 -pix_fmt yuv420p -f mpegts DrStrange_1.ts
Is that work ?
If it doesn't, try that:

Code: Select all

ffmpeg64 -i "/data/ums-user/Media/English/Doctor Strange (2016).mkv" -map 0:v -map 0:a:0 -bufsize 31000k -maxrate 30000k -crf 19 -ac 2 -ab 448k -ar 48000 -c:a ac3 -c:v libx264 -tune zerolatency -preset ultrafast -level 41 -pix_fmt yuv420p -f mpegts DrStrange_2.ts
After having tested that these videos work, or not, from your USB's TV, try to play the working one with UMS, and report your results here.

Yea fortunately the TV can play a lot of formats directly (no encoding). It basically supports all common file types/codecs so it's very likely that you have never needed transcoding until now.

If you have #--transcode--# folders enabled, can you play the file called [No encoding]?

Actually, you are using an inappropriate renderer configuration file.

Did you already tried forcing the Samsung J6200 renderer from UMS ?

If you feel happy with your, just use this slighty modified one:(that's said all your videos bitrate are wrong and all the images size specifications are unecessary as the next UMS version will automatically take care of that, because they outpass the DLNA specifications)

1)
Samsung-JS7200.conf
(6.49 KiB) Downloaded 407 times
2)
Samsung-JS7200.conf.txt
(6.49 KiB) Downloaded 412 times
3)
Samsung-JS7200.conf.2.txt
(6.49 KiB) Downloaded 401 times
4)

And take time to report back 8-)
After that we should know better what work best for your renderer.
