@neuron2

I was trying to close the opening-GOP by setting the start marker at the first I-Frame after opening the stream. Once i've opened the demuxed m2v file in DGindex it was telling me again that the opening-GOP is not closed.

I know there are several tools out their to close the opening-GOP but with an little extra feature like "Close Opening GOP"-when demuxing we could skip this "extra tool step". Not only does it save time but also HD space when using tools that have to recreate the m2v stream with a closed-gop.

Its especially time-saving for all those who like to re-author their favourite tv-shows(dvb) to dvd without re-encoding

[Edit]
You can consider this as a feature request

Why do you require to close an unclosed opening GOP? Please be specific.

Assuming you do require it, do you mean just setting the closed GOP flag, or actually replacing leading orphaned frames as well?

Most authoring tools do not accept streams with leading open gops.

By replacing you mean removing(or stripping?) till the start of the first sequence header right?

No. I mean do you just want the closed GOP flag to be set? Or do you want (in adition to setting the closed_gop flag) leading frames that are missing forward references to be replaced with copies of the first decodable frame?

Yes i would like the Closed GOP to be set, but instead of duplicating the first decodable frame for the missing reference wouldn't it be better and rather mpg conform to drop the leading incomplete GOP frames?

Lets assume the stream starts like this:

stream:
B B I P B B P B B P B B

your suggestion is to duplicate the first decodable frame which would be the I-Frame afaik to replace the forwarding reference so it would end up like this (please correct me if im wrong):
I I I P B B P B B P B B

most tools that close the opening GOP would Drop the two B frames and would start outputting the stream like this:
I P B B P B B P B B

I hope this clears out our misconception (if any)

There's a SSE2 version of Skal's IDCT in xvid's source. The output matches the 32-bit SSE2 IDCT already in dgdecode/dgindex so it should give the same quality at greater speed for SSE2 users, if you felt like adding it.

demuxing vob files direct.

Hi Neuron2 and team,

Firstly thanks for a great program, one of the marvels for video work.

I have been following the threads with interest however, could you comment on my findings please.
I have been "save project" on an mpeg file for some years with perfect results.


I decided to use Vob Blanker to get the required Vobs for my project. I then run “save project” and Demux to generate the d2v file needed.

Then using the same script I use for loading CCE (very simple script only) I noted the frame amount appeared correct but the time is different by at least 15 minutes.

If, I then process the demuxed mpeg file by generating another d2v file on the mpeg file and then load the new file into CCE the frames appear the same but the total time is correct.

Any comments would be welcome.

Regards,

Levick

Please post links to the D2V generated from the original and the D2V generated from the demuxed MPEG file. Or attach them if you wish.

Thanks Neuron2, I will need the files from my home system which is currently
transcoding the mpeg file. I will reply later on tonight my time.

Once again thanks.

You can even attach them. It's not big deal, use "Attach Files" from "Additional Options" table; right under "Reply to Thread" table

Well it seems I may have shot of my mouth without further testing.
I had a look at both d2v files and there was not much difference with the
exception of vob and mpeg file location in relation to positioning on the HD.
And the steam type.
So I did a reboot and re generated the d2v file and frame served into CCE.
This run showed the times to be perfect.
I will keep testing, but at this stage, like to apologise for jumping the gun.

Regards,

Levick.

I put DVD on the our server, and link up it using a network drive.
Server was disconnected just fo one or two seconds but encoding just freeze.
I don't know the reason but it is DGDecode or Vdub.

I don't have a network to do tests. I suggest not doing encodes across a network, especially if it is error prone.

DGMPGDec 1.4.1 beta 4

This beta is revised as follows:

* Revised the video error handling to prevent macroblocking in some error cases, and to prevent incorrect frame delivery leading to AV desync in some error cases.

* A default save file name is now set in the Save Project dialog.
