SamES 891 Posted February 6, 2020 Share Posted February 6, 2020 Yes, it should be working. We will work out why. A sample would be great, but I understand your issue. I'm testing with this sample. http://images-assets.nasa.gov/video/First-8K-Video-from-Space/First-8K-Video-from-Space~orig.mp4 This might actual be beyond the TV specs. But, if you can get a short (30 second) sample recorded in the same format that you can share privately, that would be appreciated. Link to comment Share on other sites More sharing options...

But, if you can get a short (30 second) sample recorded in the same format that you can share privately, that would be appreciated. You know what? I do remember using this video to test the TV initially, before I got the file I need to use now. And I probably already have it on a drive somewhere, or I can download it again anyway. I should be able to copy the file to the server and test to see if it behaves the same, hopefully tomorrow morning. I can also verify if it will play properly in the TV browser and confirm whether it is within specs. That should be enough to get you going hopefully, as I will not be able to get a sample re-encoded, unfortunately. I just downloaded the file to the server (remote access is such a wonderful thing!) and here is the file information from the web player Mes Médias Administrateur First-8K-Video-from-Space~orig 3m Se termine à 22:51 Ajouté le 02/11/2018 Vidéo: Audio: Informations du média Vidéo Title 4K HEVC Codec HEVC Étiquette de codec hvc1 Profil Main Niveau 186 Résolution 8192x4096 Ratio d’aspect 2:1 Anamorphique Non Entrelacé Non Images par seconde 23,976 Débit 138 356 kbps Couleurs primaires bt709 Espace colorimétrique bt709 Transfert de couleur bt709 Format des pixels yuvj420p Images de référence 1 Audio Title English AAC stereo (Default) Langue English Codec AAC Étiquette de codec mp4a Profil LC Disposition stereo Chaînes 2 ch Débit 317 kbps Taux d’échantillonnage 48 000 Hz Par défaut Oui Conteneur mp4 Chemin /var/www/html/First-8K-Video-from-Space~orig.mp4 Taille 3127MB Edited February 6, 2020 by emea.alu Link to comment Share on other sites More sharing options...
FrostByte 5052 Posted February 6, 2020 Share Posted February 6, 2020 resolution: 7680x4320 buffer size: 7880x4320 Is the buffer size typically larger than 8K? I don't see buffer size on any of my 4K movies. That's from the original file. Link to comment Share on other sites More sharing options...

I don't see buffer size on any of my 4K movies. That's from the original file. Are you sure this is 7880 and not 7680? This looks like a frame buffer holding 1 frame... This is embedded in the video file and it is what is causing the crash? Edited February 6, 2020 by emea.alu Link to comment Share on other sites More sharing options...
FrostByte 5052 Posted February 7, 2020 Share Posted February 7, 2020 I don't know if it's causing the crash, but it came from what you posted earlier. I've never seen that before. Link to comment Share on other sites More sharing options...

Right, that was VLC actually, not Emby, and the typo is mine so the buffer matches the resolution. I know a couple people at Videolabs and will ask what the value means. In the meantime maybe you want to check one of your files with VLC and see if the tools/codecs information displays the same (buffer==resolution). For my part, I've checked a couple 4K files I had lying around and VLC shows a buffer value identical to the resoution for those as well.

Behaviour is basically the same. Play does not always start, but when it does I get a few bars of the soundtrack on a black backdrop. Playback stalls after a while. 1 Link to comment Share on other sites More sharing options...

SamES 891 Posted October 10, 2022 Share Posted October 10, 2022 Are there any ffmpeg logs on the server, or just the server log? Have you tried any other 8K content with the app? Do they all fail, or just this one? Link to comment Share on other sites More sharing options...
romaing 4 Posted October 10, 2022 Share Posted October 10, 2022 I tried several. all are failing. I tried an AV1 file also it's the server file. I have no ffmpeg logs at the same time.

It should just work, but except for an issue when 8K models were first released, there haven’t been any other issues raised. That means normally 8K works fine, or no one is using it.

SamES 891 Posted October 12, 2022 Share Posted October 12, 2022 Do you mean ‘is it possible that the DS218 isn’t capable of serving this file to the TV and is preventing playback?’ It is possible, but it is only 27Mbps, so it shouldn’t be a problem. I think the server log with debug might help us to understand Link to comment Share on other sites More sharing options...

SamES 891 Posted October 13, 2022 Share Posted October 13, 2022 Are there any ffmpeg logs? I can see that it is trying to transcode due to a 'DirectPlayError'. This is a generic error generated by the TV player when there is an error trying to play the file. As a result, the server will try and transcode, but if appears that must be failing as well. The ffmpeg logs might tell us more Link to comment Share on other sites More sharing options...
