Guest asrequested Posted October 5, 2019 Posted October 5, 2019 That version stutters, just the same as with the ET version. (I really appreciate your help with this btw... :-) ) Can you complete the logging entry and post a log from that?
Guest asrequested Posted October 5, 2019 Posted October 5, 2019 Also, can you play a 4k SDR video, and see what happens?
Guest asrequested Posted October 5, 2019 Posted October 5, 2019 You can also try adding this to your conf. This will increase the log level for the video output. msg-level=vo=trace
Guest asrequested Posted October 5, 2019 Posted October 5, 2019 And I'm assuming you have the latest driver from the intel website?
brencd01 1 Posted October 5, 2019 Author Posted October 5, 2019 Yes, all latest drivers and BIOS update. Log attached from original 4K file, with the trace enabled.I'll need to find an SDR file... portable_mpv_log.txt
Guest asrequested Posted October 5, 2019 Posted October 5, 2019 (edited) And I'd forgotton about peak detection. The difference between mpv and those other players is probably that they aren't tone mapping and not using peak detection. This will increase decoder load. And if you don't have the correct opengl shader support, that too can cause problems. There's a ton of peak detection in your log, so that might be partly to blame. So lets turn that off and see what happens. Add this line to the HDR profile. hdr-compute-peak=no Edited October 5, 2019 by Doofus
brencd01 1 Posted October 5, 2019 Author Posted October 5, 2019 Making progress now... 4K SDR file plays fine. 4K_SDR_portable_mpv_log.txtThe original file without peak detection also plays fine. 4K_HDR_NoPeak_portable_mpv_log.txt
Guest asrequested Posted October 5, 2019 Posted October 5, 2019 Yeah, sorry, I'd forgotten about that. I turn it off, even though I have more than enough power to run it. I find that I prefer the results with it disabled. So if that works for you, just add that line in your mpv.conf for Theater. Are you running Windows in HDR?
Guest asrequested Posted October 5, 2019 Posted October 5, 2019 The title of this thread should be renamed 'HDR Playback in Theater Desktop is not smooth', or something like that
daedalus 434 Posted October 5, 2019 Posted October 5, 2019 (edited) you should really use the extended view of the mpv stats plugin to track down what processing part is slowing down your playback I'm using the March 10th Git build in that zip file. That's the last we can use, because later than that, live tv won't work. emby "fault"? cause live tv are just streams, can't imagine mpv could broke there something sry for hooking in again just seem to have overlooked that "issue" Edited October 5, 2019 by daedalus
brencd01 1 Posted October 5, 2019 Author Posted October 5, 2019 No, not running Windows in HDR. It's not giving me the option, although perhaps if I connected direct to the TV (rather than via the AVR) it would? The title of this thread should be renamed 'HDR Playback in Theater Desktop is not smooth', or something like that Indeed - I didn't know that at the time though...Thanks again for your help.
daedalus 434 Posted October 5, 2019 Posted October 5, 2019 Indeed - I didn't know that at the time though... you can change it, if you want simply edit your first post and then use the "full editor" to change the title

It's still in the 'release', but will be gone in the next official release. Edited October 5, 2019 by Doofus

You'll have to use tone-mapping.
