DGMPGDec 1.2.0 beta 6

neuron2 · 27th January 2005, 04:36

Here is the beta:

http://neuron2.net/fixd2v/dgmpgdec120b5.zip

Let's just say it fixes a lot of things and adds some cosmetic things.

This MPEG stuff is hard! I remember why I took a sabbatical now.

The starting codebase for DVD2AVI was a spaghetti bowl. I keep saying it needs a total rewrite, but Nic already tried that, I think.

Don't even think about it.

Is it any better now?

Still have the issue with the seek bar where it doesn't display the right frame if you move the bar too fast.

Load a vob. Grab the bar and snap it to the right all the way, fast. Repeat.

Pretty soon, you'll have a situation where the bar is at the endpoint, but the displayed frame is from much earlier. If you click 'Next GOP' it advances from the displayed frame.

It's not worth fixing that. I'd rather rewrite the entire navigation system.

What I'm interested in now are what people have real practical problems with. Obviously audio sync is a biggie, and now I am realizing that crappy transport streams are causing people a lot of headaches. I'm thinking we need DGTransportFix. It would recover the PCR and then with that stable timebase, it would expect a video frame at regular intervals of PTS corresponding to the frame rate. If one is missing, we either insert one or cut audio to match. Similarly for missing audio. Of course the hard part is the inserting of video and audio. You'd need to reencode the MPEG locally, but that is not terribly difficult.

That's what I'm thinking about.

First off, thanks for continuing to work on this great program. It is one of my most used programs.

I seem to have a slight problem in regards to .ts streams. I capture my streams via the firewire out of my Motorola box onto my computer. When I record off Discovery HD I can run into problems with the streams in Project X, but that's not too big of a deal as I just edit out commercials with HDTV2MPEG. Well, in HDTV2MPEG it is reporting the streams as video 22 and audio as 20. When I input these into DGMPEG it states that it can't find anything. When I have DGMPEG try and find the pids it finds 11 and 14. It seems to work fine until the very end of creating a project when it brings up an error that states that it can't find audio or video data and that I need to recheck my pids. An AC3 file is still created however. I just ran it again and it created an ac3 file with a different offset then the first time I ran it through with the same erro at the end. Now I'm confused. I just ran it a third time with the same error, but now two of the ac3 files have the same offset. I'm going to try and encode this overnight and see if it all works out.

Whew...I hope that makes sense.

@zeus163

I can help with it only if you put a failing source stream on my ftp site and then tell me it is there:

ftp.neuron2.net
user: guest@neuron2.net (enter it just like that)
password: guest

zeus163 · 27th January 2005, 15:35

Thanks Neuron2

I have to head out to work now. I'll up a piece of it when I get back. I'll edit out a small clip with HDTV2MPEG2 and start it later.

thanks!

Nic · 27th January 2005, 15:54

Mine turned into a spaghetti bowl too...You start writing things modular, and then realise you need to do them all together....

Maybe you and me should start from scratch one day...one day

Keep it up,
-Nic

SoulSmasher · 27th January 2005, 18:35

thanks neuron 2,
hope this should solve some of my encoding problems (on my thread)

Cyberia · 27th January 2005, 21:59

I can't find any real-world issues with this build.

The trackbar has MUCH better resolution and it looks like Preview mode is about 5-10% faster. Project time remains the same though.

Nice job!!!

TEB · 28th January 2005, 10:06

@Neuron2: Great build but...
1. Sometimes when u add a TS file and the "cant find pids" popup comes along after a few seconds.. But if u are to fast and click on detect pids BEFORE this popup comes it hangs the application.. I was able to do this with random TS yesterday...
2. Some HDV file (like the one u got from me) says cant find PMT/PAT, so no pids are selectable..

@teb

neuron2 · 28th January 2005, 14:25

@TEB

1. It shouldn't hang. I'll try to duplicate it.

2. If DGIndex says there is no usable PAT/PMT, then there isn't. You can always use Raw PID Detection to set the PIDs.

loni_blues · 28th January 2005, 15:04

Hi neuron2,

First, thanks for your great work!

There is a problem when saving a d2v file with beta 3. The file is left unfinished with the last couple of lines missing (checked with 1.1.0).

A doubt: I thought timestamp stood for the part of the movie being analysed, but at around half of the movie I am processing it starts from 0 again and ends with a value of 53 minutes for a 2 hour movie. Does that have to with the number of audio tracks?

Regards

neuron2 · 28th January 2005, 15:22

I have an idea about the unfinished business. I'll look at it tonight. Can you tell me if it was a VOB, a transport stream, or an elementary stream?

I don't know anything about the timestamps. I'll have a look at that too.

loni_blues · 28th January 2005, 16:34

It was a VOB. I noticed the timestamp thing in 1.1.0 as well.

Thanks, neuron2.

CruNcher · 28th January 2005, 19:53

neuron2 i have the same problem only that it ends in an unrecognized exception error on load of the d2v via dgdecode also a vob file, it was created via the latest dgindex the new dgdecode works fine with old dgindex created d2vs

Edit: Dgindex.exe from beta2 works

neuron2 · 28th January 2005, 21:12

OK, I got too clever for myself, apparently. I'll sort it out this weekend. Thanks for the feedback.

zeus163 · 29th January 2005, 07:17

@neuron2

I cut a piece of the .ts file that gave me that error message. I ran dgmpgdec on it and I could not recreate the error. Strange. So, I elected not to send the cut file to you.

Thanks for working on great programs like this for us!

Boulder · 29th January 2005, 18:29

A bug I just found with 1.2.0b3 :

I tried to create a project from a movie, 4 VOBs. I added them normally and then chose "demux all tracks" and saved the project. The processing went fine until the point where it should have ended (that is, the end of the movie). Instead, it kept going, and for some weird reason the resulting AC3 track became huge, it was ~3GB by the time I closed DGIndex

Choosing one track and demuxing only that didn't help either.

I ripped the DVD with DVD Decrypter, stream processing enabled, one track left out.

DGIndex 1.1.0 works fine.

neuron2 · 29th January 2005, 18:52

Yes, I'm aware of it. I'll release a fix today or tomorrow.

Thank you.

neuron2 · 30th January 2005, 19:10

Here's beta 4:

http://neuron2.net/fixd2v/dgmpgdec120b4.zip

Hopefully (need smiley with fingers crossed), it fixes the reported problems. It can demux video from VOBs now too (transport and PVA coming). It also fixes the bug in deringing that Milan pointed out.

[off to the swimming pool now]
