I really dont know how this has anything to do with dropped or repeated frames but this is my observation during testing and I still dont understand the result.
1. If I set JRiver to bitstream playing at 24 or 23.97 on the video card 1080Ti I get repeated frames on the stats of madvr. 2. If I set JRiver to PCM playing at 24 or 23.97 on the video card, I get no repeated or dropped frames on the stats for madvr, shows zero dropped/repeated frames for 4/5 days. Again something I just dont understand why... |

So in this instance with madvr, using PCM in JR is much better than bitstreaming in JR, as we dont get dropped or replaced frames and video playback is much smoother and always in sync. |

Yes. PCM is much easier to keep in sync without dropped frames. The only real downside in this day and age is the loss of DTS:X and ATMOS. If all you're doing is DTS HD MA and TrueHD, decoding to PCM will be quite perfect and eliminate the frame drop problems as you've seen.

I don't know what would explain everything being fine on my laptop monitor in FSE mode and have black bars on the side for my external monitor. Here is my original query: When I enter Full Screen Exclusive (FSE) mode on my external monitor there are extra black bars on the sides that squishes the video horizontally. This does not happen in Windowed mode. This does not happen on my non-external, laptop monitor whether it's FSE or windowed. Any suggestions? Thanks!

any reason why this is happening with this particular 1080p/hdr10/h265 file in DXVA copy back mode?
video displays fine in dxva native and cuvid modes (gtx 970). dxva copyback works fine with other types of videos. this is the only file i've come across so far that's exhibiting this issue. any suggestions? |

here is a screenshot with dxva native: i'm going to guess it's the way this particular video is encoded. guessing dxva copy back doesn't like something about it. everything else i've tried including 4k hdr10 hevc stuff works great. |

Is Built-In Video Transform Filter Settings set to "disable" and all the boxes underneath Built-In Audio Transform Filter Settings unchecked? If not, try that. |

It could be something to do with the lack of HDR metadata, "unknown properties."

Hi,
I have discovered an extremely strange bug in conjunction with MadVR. When playing low-res 25p content (SD quality) in exclusive mode I am getting weird audio dropouts through HDMI. This happens especially with NGU upscalers. My setup:
This is what's happening:
I am getting very frequent audio dropouts. The bummer is that if I use some low-end scaling algorithms such as Jinc in MadVR I am not getting any audio dropouts. With NGU (medium) these dropouts are not that frequent and my GPU load is very low. Apparently this only happens with 25p content. When switching from MadVR to another renderer this also does not happen any more. Random thoughts about this:
Does anyone have any idea what this could be? This is super strange and I cannot imagine what's going on here. Maybe a faulty GPU or a faulty driver? MadVR issue maybe? |

just doesnt sound like your system is handling what is quite a large upscale + processing, what are your rendering times in MADVR, are they sub 30ms?, do you also get frame drops / repeats?

Is this for real?

With the average render stats at around ~30ms, but the max stats can ramp up to ~44ms, what can the cause of this be? I tried to lower my settings, so that the average stats is around ~25ms, but the same thing happens. Only now the max stats is ~39ms. Too taxing for the GPU or is it something else?
Also I don't get dropped frames, but I do get a few stutters here and there. Highly annoying!

my rendering times are usually around 20ms and I don't get any frame drops (or maybe one per hour). As I said especially with NGU medium upscaling my GPU load is also only medium in that particular scenario (CPU is almost idle). Since the rendering times are also fine I don't think it comes from the GPU being too weak for my settings. Any other ideas? |
