JeremyG 20 Posted June 24, 2019 Share Posted June 24, 2019 (edited) Going on vacation and decided to use Emby to download some movies onto my Surface Pro. I usually just copy the movie files, but since i bought a video card for my server capable of transcoding with NVENC I figured I'd them down a bit and probably save battery life while watching them (less decoding) Seemed like it was taking a long time to download, so I checked Emby dashboard and saw that it was converting very slowly. (like 0.1 % every 10 seconds) Remoted into the server and its definitely using the GPU as I can see from task manager GPU is in use by ffmpeg process, however it's maxing out at 4% of the GPU for some reason and I dont understand why. You'd think if it could just max out the GPU while converting, it would be done 20x faster than it is now (and it has been taking HOURS to convert 3 movies) Edited June 24, 2019 by JeremyG Link to comment Share on other sites More sharing options...
Luke 37120 Posted June 24, 2019 Share Posted June 24, 2019 Can we look at an example conversion log? Thanks. Link to comment Share on other sites More sharing options...
JeremyG 20 Posted June 24, 2019 Author Share Posted June 24, 2019 (edited) Here's one. I notice it says "Speed 1x" during most of the decoding part of the log file. Does that mean even though I clicked "download" it's just converting it "on the fly" as if I was watching it?

Luke 37120 Posted June 24, 2019 Share Posted June 24, 2019 Go into sync settings on the server and enable full speed conversion. That should speed it up. 1 Link to comment Share on other sites More sharing options...
JeremyG 20 Posted June 24, 2019 Author Share Posted June 24, 2019 I have to get to bed now so I can get up for my flight. But some weird behavior after I allowed full-speed conversion: ffmpeg is no longer using GPU at all GPU is now used by WUDFHost.exe and dwm.exe (though I'm RDP'ed in) Totally of 6% GPU usage between them It is converting faster now...but not as fast as I would think? Looks like my cureent movie will take like 30 minutes to convert down to 4mbps I can no longer access the "Settings" for Sync in my server. I can click it but page never refreshes with the settings. (just shows whatever was last drawn) Link to comment Share on other sites More sharing options...
Luke 37120 Posted June 24, 2019 Share Posted June 24, 2019 Try rebooting your machine. Perhaps the gpu is just not available. Link to comment Share on other sites More sharing options...
bizarro252 17 Posted August 4, 2019 Share Posted August 4, 2019 Go into sync settings on the server and enable full speed conversion. That should speed it up. Thanks for this, was looking around everywhere to see why it seemed to be throttling my conversions - this let all cores ramp right up (CPU only in my case).
