LG OLED65CS6LA PVR Playback Issue

[robbie1407 5]

- I have a problem with playing back recordings on my LG OLED65CS6LA. It happens on most recordings.
it seems to be only this device that is affected. windows app seems okay. Using hd homerun tuner. emby server on synology nas.
When i go to playback a recording it will show a still screen of the recording for about 1 second then just go blank.
All you can do after this is press backup to return to previous screen.

- I have tried seeking forwards and backwards but emby does not respond. I have tried restarting emby server and synology nas. i have played back on windows app and LGOLED55BV7 and all recordings play back okay.

- I have not seen any error messages.

- I have attached server log

- I have attached 2 videos, one of the LG and one of the windows app to show playback issue on the LG

 

many thanks

Emby menu visible but streaming fails - LG OLED.

Apparently this may be resolved with LG setup options.  Often different brands and models require permissions and settings.  Viewing an Emby page on a TV app does not mean that all streaming should be working. Video streaming may be blocked by a TV setting, as well.

In latest log Error in GetSpecificMappingAsync occurs 119 times.

Emby issue?

@visproductionthat's the upnp plugin telling emby it can't configure the router.

And that's not what this is about.

i did switch locations and reverted back. although the recordings still act the same, i have set up some stuff to record to see if it acts the same. will report back.

thanks

[robbie1407 5]

After recording a few more different things, i am unable to play back as the recordings are not showing up in any of the emby apps. Although i have checked the folder where they are recorded too and they have recorded.

[robbie1407 5]

I have some information that might help. The Recordings that do not play on the LG TV will play if i start them off on the windows emby app and resume on the LGTV. The problem seems to be they recordings will not play from the beginning on the LGTV

 

thanks

[robbie1407 5]

does anyone have any other ideas what this could be? 

 

thanks

So, is LG not recognizing the media as a playable video?  Can Emby be tweaked to recognize these files?  Are the files perhaps created from a recording and not showing all the startup metadata at the beginning of the file.  If the video is remuxed to get the video data setup correctly, will those remuxed video media then begin to play?  I think it's reasonable to guess that LG does some test before accepting a media file, as playable.  If you remux and try the new file and that fixes it, that would point towards this possibility.  I am just guessing.  Media quite often has strange metadata setup and this causes failure to playback on some apps and software all the time.

[robbie1407 5]

hi there, I have made 2 short recordings off the Emby tv guide. one plays back ok, the other doesn't on my LG OLED65CS6LA.

They both playback ok on emby windows app and LG OLED55B7V.

I have not touched the file structures meta data etc... 

I have zipped up both below.

Hopefully somebody can unzip and put into there pvr folder to test playback, or look to see if they can figure out why it wont play back on my tv.

The one that won't play is interlaced, so that may be part of the problem.

Can you please play them both back, and for the one works, please confirm the playback method via stats for nerds - I suspect it is DirectPlay for the container, video and audio.

For the one that does not play, does it produce any ffmpeg directstream or transcode logs? If it does, can you please attach? Thanks

[robbie1407 5]

hi there, I have checked back and the interlaced one does not play, however there is other interlaced recordings that do play. I checked this in mediainfo. there is other recordings with scan type MBAFF, some play, some do not. so I don't think this is the problem.

To confuse you even more i have recorded the same programme on the same channel, a quiz show, 1 plays 1 does not. it seems to be luck of the draw. if I start a playback on the other lg tv or emby windows app and resume on the lgtv with the issue, it will playback ok. just does not playback from the beginning. 

ive attached to pictures with stats for nerds, everything i watch on emby is direct play.

thanks

[robbie1407 5]

failed playback server log attached.

I do not see any direct stream separate logs

 

thanks

embyserver.txt

[robbie1407 5]

just a quick update, if I force mpegts to transcode. it does play okay, although it does take 30 seconds to start. so it would seem it is an issue with the direct play?

 

thanks

[SamES 1084]

Yep, that sounds like a mixed bag. Not quite sure what to suggest.  If they're all DirectPlay and sometimes work and other times don't then there possibly isn't much we can do.  Not sure what country you're in, but I recall someone reporting issues a few years ago with UK recordings where commercial breaks could be played in a different format to the main program, so depending on whether you started playback during the program or the commercial you could get different results, although I'm not entirely sure this is your issue.

 

 

[robbie1407 5]

im uk.

also one more update.. i added the video without the meta data to emby as you would with other collections and the video acts exactly the same and does not playback.

I have a fairly large library of ts videos recorded from my satellite tv box and have never had an issue with playback. it just seems to be the ones recorded on emby

is there nothing different with the files apart from one is interlaced? the video that does not direct play back is on a tv channel without adverts.

 

thanks

There are some differences, but hard to know whether they are meaningful.

I use a HDHomerun in Australia and I always find the raw .ts output to be a bit buggy.  Audio out of sync and random other issues, but I automatically convert recordings to mkv using Emby's built-in conversion option and they play fine, even when the same .ts file has issues.  I'm not sure if it is something in the way that Emby writes the recording, or if it's on the HDHomerun end, or it's a TV issue (Samsung in my case), but either way, I've never found the raw .ts files to be overly reliable
