Thanks for your great work on DGIndex, neuron! I had an AC3 audio decoding issue with an earlier version, but after upgrading to RC4 it works like a charm.

Keep up the good work - it's definitely appreciated!

I am using DGIndex to parse Das-Boot The Director's Cut Disc 1. The movie has 4 VOB's. VOB 1-3 are progressive and VOB 4 is interlaced.

When I run all 4 VOB's simulatenously through DGIndex it reports the entire series as interlaced.

Shouldn't DGIndex report the movie as progressive or majority progressive since the interlaced part is only 10%?

DGIndex reports progressive/interlaced on a per-frame basis, so your statement makes no sense.

It depends whether you select 'honour pull down flags', 'ignore pull down flags', or 'forced film'.

Try 'ignore pull down flags'?

Let me see if I can make this more clear:

I am talking about the summary dialog and log file here.
A video can be purely progressive, purely interlaced, or a hyrbid of the two.

When I run VOB's 1, 2, & 3 through seperately DGIndex reports progressive in the summary window.

When I run VOB's 4 through seperately DGIndex reports interlaced in the summary window.

When I run VOB's 1-4 through as a group the summary window reports interlaced.

My question is why can't the summary window list the percantage of progressive or interlaced frames since it is checking each frame, i.e. Progressive(90%), Interlaced(10%)

Sorry, but this is the thread for 1.5.0, which is now frozen for new features. You'll have to ask again when the next version thread starts.

Hi Donald,

Is the "Display Size" outputting the correct information?

For example DGIndex reports this about the elementary 720x576 MPEG-2 stream with 16:9-PAL (aka: 64:45) aspect ratio signalling: -




Whereas DGAVCIndex reports this about the elementary 720x576 MPEG-4 stream with 64:45 aspect ratio signalling: -




Cheers

Please post a link to a sample of the stream.

EDIT: I've looked at the code and DGIndex just prints the display size values from the stream. So I would assume that the problem is in the stream itself.

The stream is specifying the display size as 720x576, just as I supposed.

Hi,

I have a question - is there a CLI switch to let DGIndex process only a part of an MPEG file?

I would like to explain my situation and idea. I'm working on an Avisynth transcoding application. During onpening a file, I want to use AviSynth and Autocrop filter to detect cropping. But I don't want it to take to much time. My idea is to index only 1s pieces from 10 parts of a DVD and use them to detect cropping.

Is this a good idea? Can this be done? If I use GUI I can select only a part of and MPEG file, so I do believe I can do the same from command line, but I couldn't find it in manual.

In that case, I suspect all MPEG-2 DVD sources will report a "Display Size" of 720x576 (for PAL) or 720x480 (for NTSC)... ie: it will be exactly the same as the "Frame Size"....

EDIT: Yes, this seems to be the case.... Does anybody have any spec MPEG-2 files where the "Display Size" and "Frame Size" are different?


Cheers

neuron2> Sorry, I thought the possibility might be there and just isn't mentioned in manual.

Another question - I use this command line:
Code:
exe\dgindex.exe -if=[D:\VIDEO_TS\VTS_01_1.VOB,D:\VIDEO_TS\VTS_01_2.VOB] -OM=2 -OF[C:\video\index] -EXIT
During the indexing the video preview window is black. Is this normal? If I do the same from GUI, the video is displayed.

Thank you for your reply and work on your applications.

It's normal. No decode thread is kicked off when you tell the CLI to make a D2V file.

Another thing you could try is the ffdshow source filter that appeared some time ago.

And can this be changed via a CLI parameter or should I keep this possibility for my 1.6 wishlist? ;-)

I never heard about it before. But ffdshow is "only" a video/audio decoder, it doesn't contain any splitters/demuxers. Also I'm afraid this wouldn't be a portable solution. I want to make my application portable. Thanks to avs2yuv and SoundOut it is possible to use Avisynth even if it's not installed.

Could point me to a source with more information about ffdshow source? I can't find anything myself.

Sorry for the OT.

I've confused it with ffmpegsource.

'Demux audio only' does not give a delay value by design. What would it be referenced to, the non-existent video? If the delay is significant, then there is video. If there is video, then you use Save Project.
