DLNA emby vs Windows samsung TV profiles 2023

[Yablos 0]

Hi,

 is there any guide how to "upgrade"/set video profile for DLNA server?

Lets make things simple:
- iam expecting from emby ONLY extra work with subtitles(external and embedded). No any other video transcoding at all. Audio transcoding is bonus, but not neccesary.

windows DLNA server plays almost all files(avi,mkv,mp4...), except the subtitles(mostly in the external file). Same file in emby doesnt play at all(in tv emby app even in dlna). At dlna browser is shown as "ts" or "mpg" with 0 size. OR it plays, but with heavy transcoding when it should not.

For example:
mkv 4k- hvc1,hdr,with dts and ac3 audio tracks and embedded subtitles(pgssub) = windows dlna (no problem), emby shown as mpg file 0 size

What iam tried:

- modify samsung tv profile and make "empty" values in directplay-video-container mkv- codesc audio+video = delete/empty+restart. Didnt noticed any difference.

Expected result:
- serve and play the video as it is, if there is unsupported/unconfigured audio(ie dts), just explude/skip the track
- if there is external subtitle file, include it
- OR play it the same way is it was on direct usb drive(the best one, just over the network share)

Thanks for any ideas/tips, what combinations of profiles/settings should be the closest. Maybe iam misunderstand something.

Hi Luke,
 thanks, here goes details, ill be glad with some kicking to the right direction. 

- stopped emby server, delete all logs, start server.

Important START time at log:
2023-09-11 19:14:26.552 =
- begining of browsing DLNA files, navigating to file "Alien-vetrelec-4k.mkv"
BUT
1) - emby shows it as *.mpg 0 size, but properly extracted image resolution and title name.
PLAY the file = reencoding started!! It should not, file plays. !  BUT, also encoding never stops.
= screenshot fail_dlna_emby.png
after while, iam stopped emby service, because it was eating cpu(if i let it continu, it will burn cpu for hours, even the watching is stopped...)

2) same browsing by "windows default dlna", plays, no transcoding, all seems ok(maybe DTS audiotrack is not available, but there are 2 more ac-3)

edited MKV directplay(screenshot dlna-profile.png)
- also tried empty line audio codecs part, without any change at output.

At user-settings, disabled:
NO - Allow video transcoding, if necessary, during media playback
NO - Allow changing of container formats, if necessary, during media playback

list of supported formats are here, lets focus on mkv,hvc,ac3 first:
https://developer.samsung.com/smarttv/develop/specifications/media-specifications/2023-tv-video-specifications.html#23TV_BASIC1-(UHD)

Any ideas, how to tell the emby server, to not transcode mkv files? (or NONE of the files, just subitles and audio will be perfect. If the video is not playable on device, so let the device decide and fail)

Luke, thanks for the tip, yes it worked. My personal gues was about subtitles, but it behaves as expected(not supported by device,named in definition, no transcoding, not shown = ok).

To be sure, which setup is at right path:
1) shouldnt it work also when the "Audio codecs" line is empty? That was how iam started thinking: If everything is "empty", emby do not try to encode anything = passthrought.
or
2) Name "everything"(audio+video) codecs for every container(even that not supported one, by device)

Its not problem configure it once by option 1) or 2), copy paste is our friend, just to be sure  
Thanks

Either of those is fine. It should work when the audio codec is empty.
