Can you make a screenshot of the OSD (Ctrl+J), please, in the situation where deinterlacing should be active but isn't? |

I attached OSD screenshot. OSD on madvr 0.88.21 movie 29.970fps (says source filter) deinterlacing on (says upstream) OSD on madvr 0.91.5 movie 59.940fps (says source filter) deinterlacing off (framerate) When I enable automatically active deinterlacing when needed and if in doubt, active deinterlacing, it also not working When I playing mpeg2 ts file, working deinterlace but not on mpeg2 hdtv |

This problem is caused by the wrong frame rate. If it really were 59.940fps *and* interlaced then after deinterlacing it would become 120fps, which makes no sense. I'm not sure if this is a bug in madVR, it could be. It could also be a bug in the source filter which may be caused by some other different behaviour of madVR. Unfortunately I don't have a way to reproduce this issue. But I hope if you provide the following 2 information, I might be able to tell if it's my fault or the source filter's, and then we can go from there: 1) Can you please try to find out which *exact* madVR build introduced the problem? There are many builds in between 0.88.21 and 0.91.5. I need to know which exact build broke deinterlacing, because if I know that I can compare the source code changes and maybe have an idea which change could have caused the problem. 2) Can you please zip and upload a debug log of both a working and non-working madVR build, so I can compare them? |

I remember madvr v0.90 is first version of deinterlace issue version but when I try today, only appeared black screen... so, I tested v0.90.1, 0.90.2, 0.91.5 test result was interesting. 0.90.1 29.970fps (say source filter) deinterlacing on (says upstream) 0.90.2 59.940fps (say source filter) deinterlacing off (framerate) 0.90.3 59.940fps (say source filter) deinterlacing off (framerate) 0.91.5 59.940fps (say source filter) deinterlacing off (framerate) deinterlace worked on v0.90.1, not worked on another versions. I attached v0.90.1, 0.90.2, 0.91.5 log files Log files too much big, uploaded to external site mega.nz https://mega.nz/#!1gNS2TgR!KKkN-Z9kL4fPrKmwl41EVp5RVpSeFmLlNVn65mghecg and.. I can't understand why do not working H/W Deinterlace when H/W Deinterlace(potplayer setting)+ disabled "automatically active deinterlacing when needed" on madvr setting (If enabled "automatically active deinterlacing when needed" on madvr setting, H/W Deinterlace working correctly) Why required madvr internal deinterlacing for active H/W Deinterlace? This situation occurred on all of madvr versions |

Ok, 0.90.1 and older versions detected if the decoder reported a framerate which was too high by a factor of 2 and then fixed that. That's why it worked with 0.90.1. However, I had to remove this workaround in 0.90.2 (and newer) because LAV Video Decoder has a built in deinterlacer, so LAV reports 29.970fps in case it doesn't deinterlace and it reports 59.940fps in case it does deinterlace. So the real problem is with your decoder. It reports an incorrect frame rate. Try using LAV Video Decoder instead, it will probably fix the issue. |
