SamES 890 Posted October 13, 2022 Share Posted October 13, 2022 You might be right about the DS218, although it is unusual that there aren't any ffmpeg logs as I can see that it wants to transcode. @Luke? If you put an 8K file in a USB device and connect it directly to the TV, does it play using the TV's built-in media player? Link to comment Share on other sites More sharing options...
romaing 4 Posted October 13, 2022 Share Posted October 13, 2022 (edited) yes, it works from USB device and using built in media player. I notice that one of the 3 files I have, starts correctly but failed 25 seconds later. this one is codec AV1, bitrate 13mbps = 104mbits and 30fps the 2 others running correctly : codec HEVC , one is 13mbps = 104 mbits and 24fps , the other one codec HEVC is 27mbps = 216 mbits and 60fps by the way, close to 4K but impressive on picture details ! so here is my thought : issue may be linked with bitrate limitation supported by my TV ? HEVC 8K bitrate supported is 100mbits AV1 8K bitrate supported is 80 mbits but one HEVC should not working because it reach 216 mbits which is not supported following TV specs.... I test 2 others samples working well through USB : HEVC 36mbps 30fps HEVC 27mpbs 24fps so it seems in some cases , I could go upper the TV bitrate specs Edited October 13, 2022 by romaing Link to comment Share on other sites More sharing options...
SamES 890 Posted October 14, 2022 Share Posted October 14, 2022 Can you try downloading this one, add it to your library and see if it works. : http://images-assets.nasa.gov/video/First-8K-Video-from-Space/First-8K-Video-from-Space~orig.mp4 Link to comment Share on other sites More sharing options...
romaing 4 Posted October 17, 2022 Share Posted October 17, 2022 through USB and built-in media player it does not work . it says it is not compliant. But I think it does not fit TV Specs. I will test through emby anyway but I have an issue since last tizen update. I will revert 1 Link to comment Share on other sites More sharing options...
romaing 4 Posted October 17, 2022 Share Posted October 17, 2022 (edited) ok . just test it on Emby. and it fails. here is media info : resolution seems out of the TV specs 7680 x 4320 . So it is quite normal that I can't read it . Am I right ?

SamES 890 Posted October 21, 2022 Share Posted October 21, 2022 Samsung specifies 100Mb/s as the maximum officially supported bitrate for 8K content. Note also that 8K according to their specs is a maximum of 7680x4320 https://developer.samsung.com/smarttv/develop/specifications/media-specifications/2022-tv-video-specifications.html Link to comment Share on other sites More sharing options...
romaing 4 Posted October 24, 2022 Share Posted October 24, 2022 But I can read some 8K files through USB direct . and not through emby. so the bitrate is not applicable trhough USB ? Link to comment Share on other sites More sharing options...
FrostByte 5049 Posted October 24, 2022 Share Posted October 24, 2022 (edited) The 100mb could be a streaming limit in the user's manual and probably related to Samsung TVs (and most others) only having a 100mb NIC. Sometimes you can get away with exceeding the limits, but Samsung only tests to what is indicated in the manual.

SamES 890 Posted October 24, 2022 Share Posted October 24, 2022 On 22/10/2022 at 07:11, SamES said: Note also that 8K according to their specs is a maximum of 7680x4320 https://developer.samsung.com/smarttv/develop/specifications/media-specifications/2022-tv-video-specifications.html As this is the specification in the docs, we've limited the width to 7680 for DirectPlay, so we are forcing a transcode. I'm not sure why the transcode is failing. I can transcode and play the Nasa 8K video on my 2017 4K TV, and I don't have a GPU in my server, it's all software transcoding. Please try these two tests: Turn off all GPU transcoding options, let's see if it can play with only software transcoding. The playback might be choppy as transcoding won't be quick, but the test is to see if it plays at all. Turn off all the transcode options for the user, this will force DirectPlay and ignore the width limitation. This will confirm whether DirectPlay is possible. Don't forget to press Save at the bottom of the screen after making this change These are only temporary tests, make sure you set the options back after each test or else you will create new problems Link to comment Share on other sites More sharing options...

SamES 890 Posted October 25, 2022 Share Posted October 25, 2022 Did both tests failed? Did you try them one at a time? ie: first turn off GPU transcoding and test, then turn off the user transcoding options and test? Did you test with the Nasa 8K video? Any ffmpeg logs?
