I can't figure out how to download from that site. I get stupid popups and offers all over the place.

Please use mediafire.com. Thank you.

thanks LigH
btw. problems persists if I use latest 0.5.1-DEV-rev4277 and older 0.5.0 (from http://www.videohelp.com/tools/MP4Box/old-versions#download), will now try some 4.x mp4box versions

small correction, the 0.5.0 version works,.. seems to be a problem with the 0.5.1 versions of mp4box

Certainly issues in GPAC 0.5.1:

Osmo4 0.5.0-rev4065 (stable) plays the video, reports 704×576 pixels for the video stream (correct), but a 20:11 PAR flag (wrong).
Osmo4 0.5.1-rev4277 (nightly) plays no video, reports 0×0 pixels for the video stream (wrong), but a 16:9 PAR flag (correct).

tested all the 5.1 version rev4270+ over at: http://gpac.wp.mines-telecom.fr/downloads/gpac-nightly-builds/
-> they all cause DGIndexNV to crash (will stick with 0.5.0 for the time being)
@DG: if you figure out the problem would be nice if you could report it to the GPAC devs, thanks!

I downloaded Selur's sample.

The crash is caused by the AVC stream. Its HRD parameters specify a value of cpb_cnt_minus1 that is way out of range (0-31 is legal). I added a test as follows and this allows DGDecNV to play the file without problems.

Code:
int ReadHRDParameters(DataPartition *p, hrd_parameters_t *hrd)
{
  Bitstream *s = p->bitstream;
  unsigned int SchedSelIdx;

  hrd->cpb_cnt_minus1 = ue_v ("VUI: cpb_cnt_minus1", s);
  // This field should be 0-31, so do something to avoid crashing if it is out of range.
  if (hrd->cpb_cnt_minus1 > 31)
	  hrd->cpb_cnt_minus1 = 0;
...
}
I can't know if the AVC stream was illegal before muxing or it got messed up by muxing. Maybe someone can do some experiments to shed light on that.

He could probably provide the raw stream before muxing as well. But it's not a DGDecNV issue, specifically, that's already quite certain.

Did you have access to the raw h264? We would need to check its
compliance.

I'll can recreate a new file, keep the raw and upload the raw and the muxed file and then post it over in the bug tracker
-> created a new file uploaded all the files and a small step-by-step how I created the files and posted it in the bug tracker

Why using Mencoder ?

FFmpeg or x264 is able to read avs scripts as well...

@Kurtnoise:
- x264 wasn't used directly because I disabled the 'use internal decoder if possible' in Hybrid (+ last time I check using x264 directly didn't give any speed boost with slow scripts)
- ffmpeg wasn't used as encoder, since a. I hate the ffmpeg libx264 syntax (since I always mess it up) and b. I normally use 64bit ffmpeg but 32bit Avisynth since 64bit Avisynth is far from stable over here
@neuron2: seems like the problem was the fault of mp4box and is fixed now

Hi neuron,

I've been trying to make SBS, Frame sequential or dual stream 3D movies from wmv source files.

DirectShow or FFVideoSource is always problematic with those asf files.

So finally, I decided to give it a go with DGNVTools.

Here is the sample video:

http://www.3dtv.at/Movies/Heidelberg_en.aspx Please select 720p.

I converted the video to VC1 with Graph for further processing with DGIndex.

WM Asf Reader > Haali Matroska Muxer. ( asf2vc1 is problematic btw.)



(This created VC1 works fine with any player after muxing it into a mkv or m2ts container.)

However, DGIndex never seen any video frame on this file and appearing pop-up says, "no video frames found" when I try to play.

Thanks.

Please post a link to the VC1 file you created, or an appreciable sample thereof.

My guess is that it is not in fact raw VC1 but let's see.

Sorry, the file is 260 MB and today I am living issues with upload and download speed.

I appreciate if you download the original Heidelberg video (which I renamed as "test") and convert it to VC1 on GraphStudio.

Thanks.

(BTW, I kept the video on its original size without trimming on purpose, in order to eliminate the trimming issues.)


EDIT: For this sample, asf2vc1 can create a VC1 and even it looks raw VC1, the same file cannot be opened by DGIndex:

Code:
Video
Format                                   : VC-1
Format profile                           : Advanced@L3
Width                                    : 1 280 pixels
Height                                   : 1 440 pixels
Display aspect ratio                     : 0.889
Frame rate                               : 25.000 fps
Chroma subsampling                       : 4:2:0
Bit depth                                : 8 bits
Scan type                                : Progressive
Compression mode                         : Lossy

Haali Matroska Muxer.

And please give it a go with asf2vc1 as well.

A muxer? I thought we were making a raw VC1. Please explain.

The file name is specified as test.vc1, so how can a matroska muxer output that?

You are right.

I have no working "dump filter" on Seven.
This works as a dump filter without an audio and mkv merge remux it to mkv and you can demux it to VC1 via TSMuxer.

Anyway, for this sample, asf2vc1 incidentally worked and extracted raw VC1. However DGIndex does not recognize this file as well. Please check yourself.

You ask me to misuse existing tools and hope things are OK!

I don't know what asf2vc1 is and I'm unlikely to install it.

If you want my help, you'll upload a VC1 elementary stream that you claim DGDecNV cannot open. You can cut it with DGSplit if you want to avoid a large upload.

I'll try to find a way to demux your WMV file but I don't have time to make a research project out of it.

OK, thanks.

1) VC1 created with graph
2 Muxing it to mkv with mkvmergegui.
3) Demuxing to VC1 with TSMuxer.

Final VC1 can be opened by DGIndex.

Thanks.

EDIT: It does not work everytime.
