whether or not i wanted it, megui's automatic update bumped me to version 2047.

the first thing i notice is that i keep getting "Invalid license!" dialogs when i try to load anything into it.

afaik my license is fine, and there has been no change on my network interfaces overnight...

yup, that makes sense. thanks for the clarification. following some advice from the doom9 fori, i now do the audio demux with megui's hd streams extractor, as that fills corrupted audio frames with silence, thereby keeping sync. that also means that i have to do the trimming with avs cutter (also in...

aha! so in theory (and practice), a DVB-C stream containing glitches might end up with a different number of frames in the video output (ie the dgi and avs files) and the demuxed audio files (all or some), right?

hah, not over yet. :) one more question: since you suppose that dginv gets an error-free TS as an input, during demuxing, do you also export the audio frames as-is, even if they contain a frame error? since i still get a/v desync from time to time, i'm trying to narrow down where the desync actually...

btw, i have managed to solve the issue (after none of the stream fixers i tried managed to overcome the error): around the points where stream analyzers detected serious errors, i looked for the nearest scene change, and chopped a few a frames from there (using megui's AVS cutter feature), and did t...

My software does nothing like that. It assumes that the files are correct. You will need to turn to other software, such as ProjectX, TSDoctor, etc., to get this kind of functionality. ahaaaa! that's where i was wrong, i assumed DGINV was performing some kind of sanity check on the TS files dumped ...

some more spitballing: - do you preparse the stream for invalid/erroneous packets? because if not, i can very well imagine that such a desync might occur as you have no means to look ahead and check if all valid audio packets have a matching video packet. if i had to write a demuxer (hopefully i won...

I confirm that the desync exists but it would be a bit of a project to find the exact causes. Clearly it accumulates at each file joint. All I can suggest, given that I don't know the details of this STB file storage and I am not familiar with any other tools that might help, is to write a script t...

any news? could you confirm that the desync actually happens?

A minor additional detail: while in the beginning the audio is in perfect sync, by the end it comes around 500ms too early. That means somewhere along the line the audio lost around 12 (video) frames' worth of data, leading me to believe that there might be some audio-heavy packets that get lost whi...

By the way, the whole seems to have finished, so the entire project (000-004.ts) is up if you need it.

they're up. the rest are still being uploaded, but 000 and 001 are complete.

You need to change the settings Nvidia quality deinterlacing? DGSource("video.dgi",deinterlace=2) but be aware that as the documentation states, it'll effectively double your frame rate. in my (admittedly rather limited) experience the single rate deinterlace (deinterlace=1) produces a perfectly fi...

Please don't mention commercial products here. I consider it spam. Yes, I know you were only offering information. Sorry about that. You're confusing me now. You said the files are broken into 1GB pieces and then you say "the entire file is 5GB". I will assume you mean you have 5 1G files. If you c...

Further info:
- the TC-enjoined TS file, after encoding, presents the same, progressively worse, audio desync.
- did a comparison encoding with [spam], the audio stayed in perfect sync despite the video glitches.

In my experience, the content we get in Hungary is mostly interlaced. So indeed, I'm left to my devices to decide whether deinterlacing is necessary. deinterlace=2 (the frame doubling, bobbing method) is overkill for 25fps streams as it indeed raises the FPS to 50, so I'm sticking to deinterlace=1 a...

Hi, How much would you need in regard of sample size? The entire file is about 5GB, I guess you don't need all of it -- but if you do, I have my own server, so I can upload the entire TS if needed. I've ran the TS files through ProjectX to check for stream errors, the logfile is at http://meggyfa.vp...

Hi, After a lot of trial and error, I finally managed to start using DGIndexNV and MeGUI together, and the results are pretty excellent. However, I hit a snag so far regarding an STB capture of a HD programme. The STB recorded the programme as a series of 1GB elementary TS files (I'm guessing a raw ...

Hi, I'm slightly lost in the woods regarding deinterlacing. Since I'm not going to be meddling with 23.976, 29.976, 59.whatever FPSs, and will never have to perform IVTC and suchlike, I'm looking for a simple solution. Since DGDecNV offers NVIDIA's hardware-based deinterlacing, and it seems to work ...

Thanks, I will do it there. Do you have any suggestions which topic should I choose?

Also, do you have any utilities that could create an avisynth script from the project files?

Hi, First and foremost sorry if this has been asked before (guess it was), but I hit a wall and you can probably help me. I'm using DGIndexNV (I'm a registered user) to preprocess TV-rips from my DVB-C STB. Since I'm from Hungary, channels either come in H.264 AVC encoding (for HD channels and some ...
