crusher11 842 Posted December 8, 2020 Share Posted December 8, 2020 I assume it needs to be transcoded and remuxed due to the high bitrate, but Emby isn't catching it so all I get is silence. Link to comment Share on other sites More sharing options...

SamES 878 Posted December 9, 2020 Share Posted December 9, 2020 I think this should be remuxing. Can you check the user settings on the server and confirm that all transcode/remux options are enabled. Can you attach the server log when you try and play this (ideally with debug logging turned on) Link to comment Share on other sites More sharing options...
crusher11 842 Posted December 9, 2020 Author Share Posted December 9, 2020 They are, it remuxes Die Hard as discussed in the other thread. It also remuxes Shoah, which is 24 bit 2.0 PCM. Link to comment Share on other sites More sharing options...
SamES 878 Posted December 9, 2020 Share Posted December 9, 2020 OK, from an audio perspective, remux is equivalent to an audio steam transcode. So same comments as your other thread, this should be remuxing so it is doing the right thing, but the remux is not producing any audio. So am I now correct? You have two samples, DTS-MA and PCM5.1, both which are remuxing (as they should) but neither are producing any audio. Correct? That is the problem we need to resolve Link to comment Share on other sites More sharing options...
crusher11 842 Posted December 9, 2020 Author Share Posted December 9, 2020 No, that's not correct. Die Hard 4K has a DTS-HD MA 2.0 soundtrack. This should simply extract the DTS core and Direct Play. Instead, it converts the audio to AAC and remuxes. There is audio. Unbreakable has a PCM 5.1 soundtrack. This should convert the audio and remux, but it doesn't. It plays silently. embyserver.txt ffmpeg-remux-4d77a3e0-e35a-4d27-99f1-db2e51a8e564_1.txt Link to comment Share on other sites More sharing options...
SamES 878 Posted December 9, 2020 Share Posted December 9, 2020 We're getting the threads mixed up now. I don't know why this isn't trying to DirectPlay. It may have been something that's already resolved for the next version. If you turn on debug logging temporarily and try playback again, that might tell us a bit more Link to comment Share on other sites More sharing options...
crusher11 842 Posted December 10, 2020 Author Share Posted December 10, 2020 The log I posted is good for both threads; I played both movies before uploading it. Here's another, with debug logging this time. Again, both movies. embyserver.txt ffmpeg-remux-abb72e57-b087-4333-93e7-54c521976634_1.txt Link to comment Share on other sites More sharing options...
SamES 878 Posted December 10, 2020 Share Posted December 10, 2020 From the log with debugging it looks like Die Hard tried to DirectPlay, then failed, so it requested Transcoding. However, because the original video codec (HEVC) is requested in the Transcode request only the audio has been converted so it has DirectStreamed instead. I suspect that if you try this original file from a USB drive with the TV's built in player that it may fail to play there as well. Not sure why, maybe the container is corrupt? For this file https://emby.media/community/index.php?/topic/92745-no-audio-from-51-pcm-track/&do=findComment&comment=957703 I expect that we need a channel limit on PCM files to force remuxing if there are more than 2 channels. @Luke, what are your thoughts on this? It's really an ARC bandwidth issue, but until we see support eARC support, I can't see people playing PCM5.1 any other way, and I think this is rare as it's never come up before. Having said that, @crusher11, I would suggest it would be better to add your own compressed 5.1 track to this file, then let it DirectPlay Link to comment Share on other sites More sharing options...

Is that because 24-bit and 16-bit are treated differently? I assume I'm going to have to go through my movies and look for other potentially problematic files. 4 hours ago, rbjtech said: Re : Diehard 4K DTS Core issue - If you are familiar with ffmpeg on the command line, then you can extract the DTS core yourself to confirm if it's not corrupt. ffmpeg -i input.mkv -map 0 -c:v copy -bsf:a dca_core -c:a copy -c:s copy output.mkv How would that confirm corruption or lack thereof?

crusher11 842 Posted December 10, 2020 Author Share Posted December 10, 2020 I muxed the DTS-HD MA track onto the Blu-ray, and it Direct Plays. So it's not an issue with the audio track itself. Link to comment Share on other sites More sharing options...

If it exports the entire core without issue, then no corruption ... if it errors, then there is - and this is possibly why emby resorted to transcoding.. Without the files it's difficult to investigate - but there are plenty of excellent free tools on the web to help you identify the issue yourself. eac3to, tsMuxer to name a few ..

crusher11 842 Posted December 11, 2020 Author Share Posted December 11, 2020 I remuxed the 4K and it still transcodes the audio. Link to comment Share on other sites More sharing options...
crusher11 842 Posted December 11, 2020 Author Share Posted December 11, 2020 The Revenant also transcodes the audio for playback. Something about 4K and DTS-HD MA is throwing the TV off. Link to comment Share on other sites More sharing options...
