bigverm23 2 Posted January 28, 2019 Share Posted January 28, 2019 (edited) Linux Mint 19 Intel i5-3570k VAAPI GeForce GTX 1060 unlocked for multiple streams Seems when I transcode 4k specifically 2 streams, my CPU runs about 100% while the GPU is stressed minimally. How should I investigate this? Batman4kTranscode1.txt Avengers4kTranscode2.txt server.txt ffmpeg.txt Edited January 28, 2019 by bigverm23 Link to comment Share on other sites More sharing options...
Luke 37250 Posted January 28, 2019 Share Posted January 28, 2019 Both are using the gpu, but the fact that it's burning in subtitles could be related. burning in subtitles is a very expensive operation. you could try turning off the subtitles.

bigverm23 2 Posted January 28, 2019 Author Share Posted January 28, 2019 Also of note here is that although my CPU was running at 1 hundred percent while transcoding those two 4k videos, my GPU was only running at about 5 to 10 % utilization Link to comment Share on other sites More sharing options...

bigverm23 2 Posted January 28, 2019 Author Share Posted January 28, 2019 Am I turning subtitles off at the movie level? Or at the server settings level? Link to comment Share on other sites More sharing options...
Luke 37250 Posted January 28, 2019 Share Posted January 28, 2019 Just for that one playback session prior to playback. You can do that directly on the detail screen. Link to comment Share on other sites More sharing options...
