LG G5 dropped DTS again, and Emby didn't work...?

[uniQ168 3]

It must have to do with the LG app or the TV model, since the affected shows and movies work both on my smartphone and on my PC in the browser, which are also connected to the internal network. Video transcoding is disabled, by the way — only the container format and the audio track are converted if needed. On the smartphone, DTS is played via direct playback, and in the browser it is converted to 192kbps MP3. On the LG, according to the log, it is transcoded to AC3.

Hi, we’ll take a look at it. Thanks.

I have the G5. I ditched all of my dts sound tracks and converted just the audio to 640kbps ac3 (Dolby Digital). Others got upgraded to Dolby Digital Plus from different copies,  and 4k is mostly Dolby Atmos. Now have no audio issues. I stick to these formats, as well as AAC for standard stereo (mostly TV content). This also worked better with Apple TV too. I try to have stuff Direct Play which is why I stick to these formats. DTS is a dying format and will go once the streamers kill off physical discs. LG also doesn't like TrueHD either. All the movies that were released in DTS are on streaming platforms using Dolby Digital Plus now, and some with Dolby Atmos added. You can't currently encode Dolby Atmos yourself, as the original metadata is required, which typically the content creator has. Atmos on blurays is wrapped inside TrueHD.

Almost precisely the same as my setup.
I keep the original sound track but always add a EAC3 track if no AC3 or EAC3 track is there. All stereo gets converted to ACC.

I don't think TrueHD is going away soon though, people would complain like there's no tomorrow if it got removed.
Same with bluray lot of people want physical media still, specially with needing multiple streaming services to be able to watch the right movies. Streaming at the moment is beyond stupid, they practically killed piracy but got greedy, flooded the market with streaming services and now piracy is back stronger than ever.

I can't reasonably re-encode 70-80tb of media, and that's a completely pointless exercise anyway since it's trivial for any media player (like Emby) to transform AC3 on the fly in real-time.

It goes faster than you think if you automate it.

I also have circa 70TB digitised, its quicker than you think. I used BOX4 (free and GUI) to do it en masse to Dolby Digital 5.1 640kbps (this is still a good bit rate for DD and you wont hear any worse sound quality). The tool allows you to untick soundtracks and subtitle tracks you dont want and can do mp4 to mkv and vice versa. Use a sample track first so you set up the (few) options so you dont have to configure every time. It leave s the picture at original quality, just a re-encode of the sound tracks you choose to change format, and you can leave other tracks in original quality should they already be AAC or AC-3 (DD). You may have several tracks in your video file for example....

I updated to 1.0.50 and tested DTS transcoding again but it still stops at exactly 10 Seconds into the episodes.

OK we are still looking at that. Thanks.

Just want to chime in as well, been noticing my C5 can't play DTS tracks and freezes 10 seconds in - this used to happen on my C2, weirdly was not an issue on my C4 (tho might be now that it's on Web OS 25, i guess).

I've been resorting to playback correction, but it also transcodes the video, so ends up in a quality reduction.

Can you attach some ffmpeg and server logs with relevant time stamps please.

Out of convenience. I am myself a recent G5 owner and experience the same problem. I was totally aware about missing DTS support when I bought the TV but always thought, well, Emby transcoding will take care of it. It doesn't. Transcoding works for a couple of seconds and then freezes up. I just hope, everything will resolve itself in the near future because the problem is so obvious.

I've had my G5 for almost a year now... nobody seems too worried about this.

I find that if I force video transcoding in addition to audio transcoding, you can watch your show; but it looks like shit obviously.

Here's a bundle of logs; the first film is DTS and freezes after a few seconds. The second film is DTS and for some reason plays normally (a few do this, but almost none; so there's something special about this small set), the third is another DTS HD MA, and freezes after a few seconds like the first.

Also, FWIW; there's so much identifying information in these logs; including my server's public IP address (!!) and then I just post it on the internet; it's hard to scrub it all, or to even spot it to scrub.

These logs need to either not be populated with identifying into in the first place, or an option to scrub that info when we download them. I've forgotten to scrub in the past and posted logs with my IP addresses all over them, which is mildly terrifying.

With video transcoding it always works, yes. And sometimes even without. Feels like the lower DTS bitrate the more likely Emby freezes. Could just be circumstantial evidence though.

Did you use this option?

Thank you; I didn't spot that!
Should def be on by default...

[TurkeyMan 17]

Ummm, yeah so I tried that (it is enabled by default, so it was already on!), but my logs are distinctly not anonymised, not at all as I can see.

[Neminem 1516]

Devs will have to answer that

I think the anonymise feature only works if you then download the logs via the UI.  If you just zip up the logs folder from the server then I think you get the raw data.  I have downloaded them now so you can delete if you want.

Question: Am I going to be able to determine which playback events are first/second/third files from the logs?

 

I should be able to work it out from the logs if you give me the names of the files that played fine and the names of the ones that don't

[TurkeyMan 17]

I downloaded them by the UI, in 2 different ways (there are 2 ways presented in the UI to download). One is a download from the log list, the other is a download button from inside the individual log file viewer (where the option to anonymise is visible). Both methods downloaded identical files, and they were full of my names, public IP addresses/network details, and filesystem details. What is an anonymise option intended to redact?

@sa2000might be able to assist with understanding why the anonymised logs still have server info in them

Maybe not everything is anonamized. We should definitely be hiding api keys, emby tokens, public ip addresses, server name, user id

Could you send my by private message the raw log files and ones you downloaded through the emby web logs download interface
