MadVR and LAV possible Bug

Playing specific files from specific resume pos is not working.
(i think when pos is short bevor keyframe everything is ok).

LAV starting from 0.71.0 is not working.
newest mpc-hc has integrated LAV 0.70.2 which is working.
EVR Renderer is working with all versions of LAV.

you can also test with mpc-be with following setup:
mpc-be player - with prefered external filter (LAV Splitter Source and LAV Video Decoder)
(load file with resume pos 01:04)

First we need a Stopped Graph, with this test file:
https://drive.google.com/file/d/12T5...pHT637GRw/view
or
https://drive.google.com/uc?export=d...tI83souI_aGTEb


Filter Graph with LAV Source and LAV Decoder and MadVR Renderer.

when we start file playing with resume pos the screens is black.

not working:
Code:
REFERENCE_TIME rtResume=640000000;
pMSeek->SetPositions(&rtResume, AM_SEEKING_AbsolutePositioning, NULL, AM_SEEKING_NoPositioning);
pMC->Run();
not working:
Code:
REFERENCE_TIME rtResume=640000000;
pMSeek->SetPositions(&rtResume, AM_SEEKING_AbsolutePositioning, NULL, AM_SEEKING_NoPositioning);
pMC->Pause();
pMC->Run();
working:
Code:
REFERENCE_TIME rtResume=640000000;
//first seek to keyframe
hr = pMSeek->SetPositions(&rtResume, AM_SEEKING_SeekToKeyFrame, NULL, AM_SEEKING_NoPositioning);
pMC->Pause();
				
//wait until Ready
__int64 endclock = GetTickCount64() + 2000;
OAFilterState pfs;
while (pMC->GetState(10, &pfs) == VFW_S_STATE_INTERMEDIATE  || pfs != State_Paused) 
{
   Sleep(10);
   if (GetTickCount64() > endclock)
     break;
}

//now seek to Real Pos					
hr = pMSeek->SetPositions(&rtResume, AM_SEEKING_AbsolutePositioning, NULL, AM_SEEKING_NoPositioning);

I use madVR in Kodi DS Player. And I use LAV Filters with it, as well.

Never had a problem in resuming files from where I left them.

Same with Zoom Player, no issues resuming from the last location with LAV + madVR.

TS files are not always perfectly seekable, its just the nature of the format - its designed for broadcast and streaming. If you need flawless seeking, remux to MP4 or MKV.

@nevcairiel
have you tried my setup - or do you just want to tell me live with the problem.

TS and Live is my main application, and the file is a public Test Demo.
no Problem with EVR, C-EVR
no Problem with older LAV Codec and MadVr.
other players maybe dont have a prob (maybe they always start to render at the begining of a file, and then resume to position, but thats not smooth).

I have also a lot of mkv files with that problem (but these files are not pulbic downloadable).

plesae test my posted setup.
regards, onur
