@tranfa
It seems that someone reported it.I guess you have to be patient. I'm waiting too for the dxva2(native)10 bit HEVC black screen to be fixed cause I can't play high bitrate 10 bit HEVC.DXVA2(copyback) is a slideshow with 10 bit HEVC.Non 10 bit HEVC play fine with DXVA2(copyback) and the weird is that my GPU supposedly can handle it.For now only option is EVR(CP) but luckily I am fine with 20GB movie which I can handle with software decoding. Seems that I can go till 10bit HEVC ~50Mbps for now with software but I am on the edge,not bad. Last edited by Damien147; 28th February 2017 at 12:57. |

I have more success with DXVA2 (native) too in general but with Madvr(and 10 bit HEVC ) I get black screen.About the judder smooth motion in Madvr doesn't go well with you?

not everyone has the same issue so it is not 100% clear this is a madVR issue.
high CPU usages doesn't make a lot of sense with copyback. it's not like the copy back for 10 bit images is a lot bigger/harder than 8 bit. and no the codec doesn't matter with copyback. |

The thing is that I can't use DXVA2 with everything in general using Madvr.Copyback was gonna be the best thing but for some reason my system can't handle it with 10bit HEVC,too slow.Others with same GPU can handle it.So...only software decoding for now.For the 99% of situations I'm fine,so no big deal.It's not an everytime/day problem.
Three more here with AMD rx4x0 reproduced the 10bit HEVC dxva2(native) black screen.We all four had normal playback with EVR(CP). If I get worst PQ with dxva2(native) I ain't gonna use that though.(oh boy...someone's gonna shoot me.) I have an old cpu(i5 760 oced 3800) which performance wise is like i5-2400(Sandy Bridge).My gpu(rx470) can handle 10bit hevc with DXVA2(copyback) as other users here report but I can't.Could it be a bottleneck from cpu for some reason?Some instruction missing or something?I don't get high cpu load with DXVA2(copyback) to see the ''bottleneck'' if it exists but 10 bit HEVC is slideshow.

I have same problem you have. Black screen happens with madvr since the NGU pixelart update. Previously 4K 10 bits worked fine with madvr with MPC HC/BE. With EVR (cp) I get judder in MPC BE and HC. This was always the case. But now, only potplayer seems to be smooth with EVR. Black screen with madvr. Something changed in madvr.

I haven't updated MPC HC and now I experience black screens with madvr pixelart and 4K. In the mean time I have updated the AMD drivers a few times. |

Using latest official MPC HC with 0.69 lav and latest gpu drivers.It seems that the black screen affects only AMD users.You get black screen specifically when playing 10bit HEVC with DXVA2(native)and Madvr.Nvidia side all good.

Solved, thanks to this debug report. Actually, Madshi's comment about wrong configuration was enlighting: "1) You only have 60fps, 72fps and 75fps in the display mode list. At the same time you have deinterlacing turned *on* and forced film mode turned *off*. Which IMHO classifies as a bad configuration. Let's say you actually played a natively interlaced PAL video with this setup, there's no good refresh rate that could be used! I don't really understand your setup. It seems you're thinking that you don't ever need video mode deinterlacing. If that's the case then your list of refresh rates is ok, but then you should turn deinterlacing off or switch it to film mode. If you do that, madVR should switch to 75fps just fine." Once turned deinterlacing off, instead of leaving it in the "automatically activate deinterlacing when needed" status (which if I'm not mistaken is the default), the display modes assignment started to work perfectly as expected. Thank you all! |
