Even Rocky has limits!
Re: DGDemux development
Iron man 2, mpls 00847. DTS-MA track.
Before 1.54.34.500 it perfect, after has shift +10ms. I guess there is place where last m2ts starts. Maybe there are 2 identical frames and 1 should be deleted, but for some reason it wasn't.I fail to find duplicate frame, but there starts difference +10ms (vs eac3to), and stream length is +10ms vs BDInfo information. I'm not 100% sure that it's issue, but if you look at it, it will be great.
Re: DGDemux development
Great report, redbtn. Thank you. Now I can get on it tomorrow.
Re: DGDemux development
How to get the duration of a BD disk so precisely by BDInfo or other tools? I also tried BDInfo 0.7.5.5 (GUI), however it reports the duration as hh:mm:ss without the precision of milliseconds.redbtn wrote: ↑Tue Dec 03, 2019 5:32 pmIron man 2, mpls 00847. DTS-MA track.

Re: DGDemux development
1.54.34.500 is the time at which the gap between the last two M2TS files occurs. At each gap, processing is done to see what adjustments are necessary. In this case at that gap, DGDemux sees an accumulated desync that is below the threshold (approx. 5ms for DTS HDMA) for requiring correction. Therefore, no audio frames are deleted or added at this gap. AV sync during the last M2TS appears spot on to me when playing an MKV made from the demuxed files in MPC-HC.redbtn wrote: ↑Tue Dec 03, 2019 5:32 pmIron man 2, mpls 00847. DTS-MA track.

So, it appears that eac3to deletes a frame at this point and DGDemux does not. As I have mentioned several times, DGDemux and eac3to use completely different algorithms to decide when to delete audio frames. The decision at each gap will depend on what has been done at all the previous gaps.
Bottom line is I don't see a problem here.
Re: DGDemux development
Thanks for investigating! DGDemux is smarter than eac3to, even on non UHD BDs, it's good! So, it seems I have no issues for now anymore. I'll check UHD seamless disks if I find them. But it will be much harder to find bugs.Rocky wrote: ↑Wed Dec 04, 2019 9:55 am1.54.34.500 is the time at which the gap between the last two M2TS files occurs.

Re: DGDemux development
Great to hear, redbtn. You've been really helpful in DGDemux development.
Ah, that BDInfo report feature. I never noticed that before. Cool!

Re: DGDemux development
Thank you very much. I never notice this before.
If I have not scan the whole disk before entering this feature, will the "Length" be detected accurately?
And I have not figure out how to make it on the command line version.
Re: DGDemux development
Today I find another DIY disk with demux problems by DGDemux. The duration of the obtained audio files deviate from that of the video stream.
But none of other softwares such as eac3to, tsmuxer, mkvtoolnix and ffmpeg can demux it correctly. I am not sure whether it is necessary to upload it for your analysis. This disk has only one main m2ts and can be played normally by potplayer.
Re: DGDemux development
Sure, go ahead and upload it. Happy to look into it for you. With only one M2TS the gaps processing is not involved, but there may be some other issue that can be fixed.
Re: DGDemux development
Why DGDemux GUI window becomes inactive after clicking "Demux"?
Re: DGDemux development
Not blonde so I can have razor sharp intellect too, way beyond a moose and squirrel. Silly boys, stub out decoder and DGIndexNV can run but without display (so NV not needed). Too difficult to understand? Come with me, I will help you to understand, we will be forever.
Re: DGDemux development
Smart girl! DGDemux/DGDemuxGUI get replaced by DGIndexNV running in non-NV mode. Can display flag and eagle. Imperialists have moose and squirrel for warriors! Tashie, tell me again, what are we doing?
Re: DGDemux development
Sorry, sometimes I don't have enough English skills for explaining what I mean. I don't mean that while DGDemux doing things you can't move window or Abort, I mean after clicking Demux title changes from blue to white, I think it's called "inactive window".
Ps: I think it happens because DGDemux GUI calls DGDemux.
Replace DGDemux? What you mean?
Re: DGDemux development
A newbie question arising when check the output of DGDemux. For Blu-ray disk which has only one m2ts for the main playlist, should all the audio streams have the same duration with the video stream?
Re: DGDemux development
We say that the window lost focus. I never noticed it, but OK I can grab back the focus. Not sure without looking who is getting the focus.redbtn wrote: ↑Thu Dec 05, 2019 5:38 amSorry, sometimes I don't have enough English skills for explaining what I mean.

Never believe fake news from Russian spies!Replace DGDemux? What you mean?
Re: DGDemux development
Not always. Sometimes there is silent video at the start and/or end of the stream, often just black frames without audio.
As I mentioned, if you like to upload the problematic disk we can look at it.
Re: DGDemux development
Where can I find the spy? I live in Russia, I catch up him around his home, haha!
Re: DGDemux development
He claims to be from Pottsylvania, but we have evidence from Shifty Schiff of connection to Russian Fearless Leader Putin. All roads lead to Putin!
Re: DGDemux development
OK, I am starting this upload now. That's a long way for my poor networks. Besides, I still wonder whether is it the problem of my way I get the duration.

Re: DGDemux development
8 million seconds for an audio file? The movie is 2000+ hours long?
No wonder it's a long upload.
