FLAC not playing on LG SMART TV  OLED65E7P

FLAC files that play when on the TV USB stick do not play when using EMBY LG Smart TV client.

Tries, gives up, tries next track on album, gives up again, until end of album.

Server Log attached

Luke,

Thanks.  I tested. On TV it seems better - no error loop thru all albuns (Error screen stops on OK/Done button ---Playback Error: No compatiple Streams found). On Server - no direct play stream found for flac. Enclosed server log.

Hi @@lai, on server, what do you mean? Are you referring to using the web app? Thanks.

Hi Luke,

 

Just peeked at the server log I enclosed and saw the Direct Play messages ...

on Dashboard - Recent Activity just messages like those below (timestamps below differ from those on log):

I don't quite understand. Is there a problem, or no?

[lai 0]

Yes...  flac files still do no play on the LG webos app.

 

After the LG app update now the symptom on TV is different -- after selecting a flac file to play, TV tries to load, does not play and display a modal error message  on tv screen  PLAYBACK ERROR: NO Compatible streams found and a DONE button which if pressed repeats the this cycle tries to play, display the error message stops-- 

 

(before the app update, the app on TV would loop thru all flac files without playing, and sometimes the app would crash after a certain number of files).

[Luke 24253]

Ok, we'll retest this, thanks.

I can con confirm latest wont play flac files back.

[Luke 24253]

It's resolved for the next release of the app, thanks.

Is it trying to direct play it?

the logs are so big let me try and pull it and upload it.

Here is my log when i play Flac files it always transcode 

 

 

ffmpeg-transcode.txt

[CarlosLima 77]

I have a large collection of FLAC songs and to not transcode, just change the extension of the files to MP4.
The file does not lose size and does not lose quality and reproduces in Emby, LG TV, without transcoding and with excellent audio quality.

@@medric, we did what we had to do, because previously they were failing with the LG audio player when direct playing. 

 

@@SamES can provide more information. Thanks.

Here is my log when i play Flac files it always transcode 

 

 

It's transcoding as it's failing during playback so we fallback to transcoding rather than giving a 'No playable streams' error.

 

The problem is that the maximum supported profile level for H.264 @ 1920x1080@60P is 4.2.  Your video is Level 5.0 (50).  I don't think 10-bit 1080 content is supported.

It is not the audio that is the problem, it is the video.  

 

To confirm this I disabled FLAC support which should cause it to only convert the audio (DirectStream) instead of a full transcode.  It does attempt this, but still throws an error on the video stream which causes it to transcode.

 

Sorry, there is nothing we can do to prevent this as it is outside the LG spec for this type of video.  But I can confirm that in your case, the video is the problem, not the audio.

 

@@Luke, ideally we need to be able to limit the profile/level based on resolution and codec as the LG spec is 4.2 for 1080/h.264 and 4.1 for 1080/hevc but 5.1 for 2160 content.  On Samsung this also transcodes with transcode reason 'Video profile not supported'.  Not sure why this is being detected differently.

 

This is my test sample which is similar to yours

@@Luke, web0s also detects as browser.chrome so '|high 10' is being added when it shouldn't be.  This doesn't stop transcoding, but it explains why it attempts to DirectPlay.
