mystic.bertie 23 Posted June 16, 2021 Share Posted June 16, 2021 Recently i noticed that some of the videos i play make NUC pc cooling fan go very loud and it seems to be whenever i play HEVC files. The fan noise is so bad that its drowning out the sound, i cant turn the volume up too high because of my neighbours. If i play the same file using VLC i dont even hear the fan increase at all. Why is Emby causing this to happen when VLC can play the file effortlessly? cheers guys ;) Link to comment Share on other sites More sharing options...
Carlo 4331 Posted June 16, 2021 Share Posted June 16, 2021 Hi, this would likely be because you're trying to playback HEVC on a client that can't play it back so the server has to transcode it to AVC. Likely you do not have GPU assisted transcoding so it's done on the CPU which makes it run hot and of course kick in the fans. What client are you currently using? 2 Link to comment Share on other sites More sharing options...

Im using Emby Theatre 3.0.15 ans Emby Server 4.6.2.0. The video is direct playing when this happens. Like i said the fans are quiet when using VLC.

Carlo 4331 Posted June 16, 2021 Share Posted June 16, 2021 Try this for me. Play back one of these media files then go look at your logs. Do you see a log file starting with ffmpeg with the same time as when you started playing this file? If so upload that ffmpeg file here please. 1 Link to comment Share on other sites More sharing options...

generiq 113 Posted June 16, 2021 Share Posted June 16, 2021 My guess is that the video is 10bit and your hardware doesn't support the pixel format, so it falls back to software, and then the fan kicks on. Try auto copyback. 1 Link to comment Share on other sites More sharing options...

Try auto copyback. Thanks for your reply. The bit depth is 8 bit according to Mediainfo. I tried auto copy back but it did not help im afraid.

Carlo 4331 Posted June 16, 2021 Share Posted June 16, 2021 OK, thanks for checking. I just went back and re-read your op post. Do you have a NUC you use for running Theater as well as a separate Emby Server? 1 Link to comment Share on other sites More sharing options...

Carlo 4331 Posted June 16, 2021 Share Posted June 16, 2021 OK so what is likely happening is that the client, not the server is trying to process this file and that is what is kicking in the fans. If you play this back in Theater and bring up stats for nerds what does it show? Can you grab a screen shot? 1 Link to comment Share on other sites More sharing options...

generiq 113 Posted June 16, 2021 Share Posted June 16, 2021 There's your answer. It's dropping frames. Switch your hardware acceleration back to auto and change the renderer to GPU. 1 1 Link to comment Share on other sites More sharing options...
