Problem with unwanted transcoding

[squadjot]

Hi

I got a samsung J5500 (2015 model i believe)..nobody cracked the code for making UMS transcode to this TV, but luckily the TV plays almost anything you throw after it, natively.

Anyways, today i ran into a problem with a MP4 that UMS thinks needs transcoding, and i don't understand why.
I can play the file with the "no encoding" option from transcode folder.

Ultimately i want the file to stream with the internal subtitles (which transcode folder options does not provide)

Normally this isnt a problem

Can anyone help me out?


Side question, would there be a way to force the TV to stream everything?
I tried adding *.* to the "skip transcoding etc etc" in the GUI but that seemed to have no effect

It's impossible to figure out why the file is transcoded since the log files aren't in "trace mode". As long as you choose "no transcoding" in the transcoding folder, the file is sent as-is, including internal subtitles. If the subtitles isn't displayed then, it's probably because the TV doesn't support the subtitles format. That can also be the reason why the file is transcoded in the first place.

You should be able to disable all transcoding by setting

disable_transcoding = true

in either your renderer configuration (to only apply to a particular renderer) or in UMS.conf to apply to every renderer.

It seems that your MP4 file has TX3G subtitles so if your TV supports it, let us know and we can add that line.
Also can you try replacing:

Supported = f:mp4 m:video/mp4
Supported = f:mp4|mpegps|mpegts m:video/mpeg

with:

Supported = f:mp4 m:video/mp4
Supported = f:mpegps m:video/mpeg
Supported = f:mpegts m:video/vnd.dlna.mpeg-tts

and let me know if that fixes transcoding?

Also it would probably be good to change:

TranscodeVideo = MPEGTS-H265-AAC

to:

TranscodeVideo = MPEGTS-H264-AC3

since that is nicer on the CPU

Thanks for replying!

@SubJunk, thanks i'll try that when i get home.
@Nadahar, oh sorry i thought it was in debug mode, i'll make a new in trace mode if the problem still persist

@squadjot I'm pretty sure your TV doesn't support TX3G subtitles. That would explain both why you don't see any with the "No transcoding" option and why UMS wants to transcode the video. The only way to get this to work with subtitles is most likely to get transcoding to work with the TV.

Yea you're probably right: viewtopic.php?t=4075
I've been trying to get this TV to transocde since i got it.. had numerous attempts from Sami, but no luck..and i kinda gave up.

But i'm willing to try any suggestions you guys might have. (Still have to try the suggestions SubJunk mentioned)

[squadjot]

@SubJunk

Supported = f:mp4 m:video/mp4
Supported = f:mpegps m:video/mpeg
Supported = f:mpegts m:video/vnd.dlna.mpeg-tts

The above didn't fix transcoding, but i might have to play around with some other variables to make sure.

@Nadahar
Yea, the TV does not support TX3G subtitles, and explains why UMS tries to transcode.

Was that with TranscodeVideo = MPEGTS-H264-AC3 too?

There are a lot of transcoding options in that renderer config so it is weird transcoding doesn't work.
Could you try to force detection of the TV as another renderer and see if any other configs work for transcoding? It might give us some idea of what needs to change

The reason there's alot of transocding options, is because i've been trying alot ..
The closest i came to playing transcoded file was this: https://www.youtube.com/watch?v=URyq8Ug2boY
Starts, but then restarts and the sound is async

As mentioned i kinda gave up, but if you have some specific tests you want me to do, i'll do it for the sake of the communitaeh
