AdrianW 1058 Posted October 19, 2020 Posted October 19, 2020 Something appears to have changed with video playback recently. I used to use hardware acceleration mode "Auto (copy back)" but today I noticed some frames being dropped (but only on 1080 50fps content). I tried a bunch of different settings and finally found that a HW acceleration mode of "None" actually worked fine with that content, which is weird as I previously needed to use "Auto (copy back)" to get decent playback. I am running ET on an older NUC which only has an intel HD5000 iGPU, but's it's been fine with all content for years. I noticed that the Stats for Nerds display has also been altered. Maybe that's related. (Note: mode "Auto" never works properly on my NUC).
AdrianW 1058 Posted October 20, 2020 Author Posted October 20, 2020 No, Auto has never worked on my NUC. It always ended up stuttering and dropping frames. I tried a few different acceleration options yesterday - at least one of them ended up with the video being transcoded, which is ridiculous (considering the NUC is the server as well). I'm going to leave it on None for a while, hopefully all of my various content will continue to play.
sooty234 266 Posted October 20, 2020 Posted October 20, 2020 The only way I can think of that would make it transcode in those circumstances is that the GPU doesn't support the pixel format. I'm pretty sure you have logging configured for mpv. Can you post the log?
AdrianW 1058 Posted October 20, 2020 Author Posted October 20, 2020 I'm not sure which acceleration option caused the transcoding. And, I haven't got mpv logging switched on, the oldest log is from about 5 months ago. I wonder what was changed in ET (or in mpv) to cause the change.
sooty234 266 Posted October 20, 2020 Posted October 20, 2020 What version of mpv are you using, and have you recently updated your GPU driver? Adding logging to you mpv.conf would be a good thing. https://mpv.io/manual/master/#options-log-file
AdrianW 1058 Posted October 20, 2020 Author Posted October 20, 2020 ET will be using whatever version of mpv comes with ET. I haven't manually updated the video driver in a long time (years). According to Device Manager the driver version is 20.19.15.4835 with a date of 16/10/2017, so I'd say no. There was a major Windows update to version is 2004 (19041.572) the other day. I'll switch mpv logging back on.
sooty234 266 Posted October 20, 2020 Posted October 20, 2020 Theater is about to be updated, and that has some big changes. You might want to wait for that. Maybe update your driver, too?

Luke 42077 Posted October 20, 2020 Posted October 20, 2020 Yea for three year old drivers, I would suggest doing that.
