Sammy 735 Posted October 22, 2017 Share Posted October 22, 2017 I'm having issues with stuttered / juddery playback using frame rate switching with mpv. Here's some screen grabs of my settings and the logs consistent with the time this occurred although it is occurring often. Last night I had to shut off frame rate switching in order to watch the movie without getting nauseous.

Luke 37009 Posted October 22, 2017 Share Posted October 22, 2017 Try setting the app back to default settings. Link to comment Share on other sites More sharing options...

Luke 37009 Posted October 22, 2017 Share Posted October 22, 2017 Do you remember which ones you changed? We are probably at the point where we have too many settings in the UI now and need to consider removing some. @ Link to comment Share on other sites More sharing options...

We are probably at the point where we have too many settings in the UI now and need to consider removing some. @Just turning off frame rate switching but leaving the rest as posted in the OP fixed it. I have had frame rate switching work just fine but last night was unwatchable. Look at all the dropped frames in the "Stats for Nerds" in just a minute or two of playback.

Guest asrequested Posted October 23, 2017 Share Posted October 23, 2017 (edited) A couple of things. First, what GPU are you using? Second, you have HWA set to auto and it's using dxva2-copy. That should be d3d, assuming you're using windows. Third, the whole bottom section of settings requires extra processing. I leave all those, alone. Without knowing your GPU, I'm shooting in the dark. Do you also know how to get an mpv log? That would be helpful. But I think we need to manage GPU usage, more efficiently. I was recently getting frame dropping, like that. I reconfigured a great deal, to get it to stop. Hardware and software, but I think my issue was with something I was using.

Guest asrequested Posted October 23, 2017 Share Posted October 23, 2017 You should also disable display sync. That will cause a lot of dropped frames Link to comment Share on other sites More sharing options...

Sammy 735 Posted October 23, 2017 Author Share Posted October 23, 2017 (edited) Recommendations on a good GPU around the $100 price point would be nice. My Radeon HD7850 gave up the ghost recently so I'm using on board video right now.

Sammy 735 Posted October 23, 2017 Author Share Posted October 23, 2017 Works great. No Judder at all. Sent from my SM-G930P using Tapatalk If this is to be the best answer then does frame rate switching actaully work in mpv? Seems to be a "maybe" answer because it depends on the GPU? Shouldn't this work with iGPU? I had it working long ago, back in 2011, on an i3 iGPU with madVR (no advanced settings though). Why can't I expect that on a 4th generation i5 iGPU in mpx?

Guest asrequested Posted October 23, 2017 Share Posted October 23, 2017 (edited) Ah that was why it chose DXVA2 copyback. No, you need win 8 and up. So with copyback, it's writing to your RAM. That could possibly be why you have dropped frames. Unfortunately DXVA2 is not well supported, now. But there is a way for you to try it. Do you have an mpv.conf?

Guest asrequested Posted October 23, 2017 Share Posted October 23, 2017 (edited) You can set your HWA to auto and put this in your mpv.conf hwdec=dxva2 opengl-backend=dxinterop And disable display sync Edited October 23, 2017 by Doofus Link to comment Share on other sites More sharing options...

Coupled with display sync, I would expect frame dropping. Your first test should be HWA auto and display sync off. Link to comment Share on other sites More sharing options...

Your first test should be HWA auto and display sync off. That is where it is set right now. No frame drops but no frame rate switching either.

Guest asrequested Posted October 23, 2017 Share Posted October 23, 2017 So with those settings, frame rate switching doesn't work at all? If that's the case we need to get you set up with logging so @@randomevents can take a look. Link to comment Share on other sites More sharing options...
