Correct, it doesn't expose the SEI data. While one could parse that manually out of the bitstream before giving it to CUVID, thats just not done, and would also be quite annoying.

I seem to have a problem with x265 (H.265) video files.
The image freezes but the audio continues playing, resulting in massive dropped frames. It happens sporadically. I made a video about it with madvr statistics enabled. https://www.youtube.com/watch?v=Ljlp67uHH_0 It even happens with a 300mb re-encode video file. Such as with e.g. Annabelle.2014.BluRay.1080p.H265-20-40. If needed here is the Mediainfo output of the file: https://pastebin.com/p2M9X2QM My pc specs are: - i7 4770k - geforce gtx 650 ti (latest drivers) - 8gb ram - w7 64 bit My MadVR settings are close to default. And my settings in LAV are also on default. I only changed the hardware decoder to dxva2 copy-back. Can anyone tell me what is causing this to happen? Any help would be greatly appreciated. Thanks! |

It's really good to have D3D11VA support now, probably avoids a fair amount of trouble or oddities for every driver. |

This is almost pretty unbelievable that you need a super high end system just for playing x265 (h.265) files. I'm stunned. I can't imagine how many people are still in the same boat as me. |

GTX 970 is not good. GTX 950, GTX 960 or GTX 10xx (Pascal) would be better. (Or Intel Kaby Lake and later)
But why not just use software decoding? Your CPU is more than fast enough for at least 1080p, probably also for most 4Kp24 stuff. |

no a 970 can't do it you need a 960/950 or newer card pascal card.
and of cause you need new hardware for new codecs how could a GPU old than a new codec have fixed function hardware decoder for it? even 1030 has a fixed function hardware decoder so no need for high end hardware you just need new hard. |

And it will automatically use my CPU instead of my GPU? Interesting. Thanks for the tip. I'll try it out. |

So you say that brightness is the right thing to have? Talking about madvr here.

One more question. The other day I tried to reproduce my problem on my fathers pc, since I didn't had a clue what was going on and he has a R7 240. So far his pc didn't had the freeze image issue (maybe if I waited longer it still could have happened). But does this mean that the R7 240 supports HEVC?

No, R7 doesn't support HEVC at all. Then LAV simply falls back to software decoding. Good software decoding is often better than "bad" (no ASIC) hardware decoding.
If you open LAV Video settings during playback it will tell you which decoder is currently active. ("avcodec" = (ffmpeg) software decoder) |

For my I can't live without (svp, madvr and lav filters), I wanna narrow down the reason for the major improvement that was talking about, to share with other users of SVP, and for that I need help of the people in this forum who's have a bast knowledge of interaction of settings between programs filters and renders
