You have just added the dataset version EFO V1. You have to add one more version for this dataset. So you have to click on the "Options" button and then choose action "Add Version to Dataset".
Then you select the dataset below EFO and the upload the new version let's say V2 repeating the previous steps. Now D2V is completely functional as it requires minimum two dataset versions in order to a change detection makes sense. You are absolutely ready to check all the functions of the D2V system From the first screen menu you have three more options to login as a new user that keeps its own set of changes and datasets. This file contains Virtuoso credentials information plus the following properties:.
You can found a demo video showing the basic functionalities. You can view it by open the video. For any information about the D2V system please contact Ioannis Chrysakis via e-mail: hrysakis ics.
Best Student Research Paper Award. Skip to content. If we execute this tool, we see the following in the generated log:. Clearly, there is something fishy right at the beginning of the stream in this case it was a jump in the SCR. To solve this, we can start our project one GOP in from the beginning of the stream, i. When you select the Analyze Sync tool, a popup will appear allowing you to select the audio ID to analyze, and then a file open dialog will appear.
Don't confuse it with the audio PID. Note that for a displayed delay value to be usable and correct, you must start your project at the corresponding I frame. But we usually want to output a stream with one consistent field order, and some tools, such as Telecide and Leak KernelDeint, require a fixed field order. Indeed, AVI does not carry a field order property!
This affects only streams containing field order transitions, of course. When field order correction is applied using this tool, the uncorrected D2V file is renamed so that it ends with the extension ". The corrected version is output as the usual D2V file. This tool should be used only when you have reason to believe that field order transitions are present in the stream. For some pathological streams, however, you may find that the field order correction causes problems that you don't encounter when using the ".
Therefore, it is always advisable to treat the correction as an advisory and to test both the good and bad D2V files. This tool is intended for power users. When selected, you are prompted to open a d2v file. After the d2v file is selected, a text file is created that contains an analysis of the contents of the d2v file, and the system's editor is opened on that text file.
If your d2v file is named "movie. The contents of the text file will be readily understood by power users. These options open the respective documents in your browser. To work, the files "QuickStart. Do not rename these files. Currently, the display window displays only I frames in navigation mode because they are possible selection points for cutting the video , which usually appear about every 12 to 15 frames. This makes the video appear to jump when stepping, instead of moving smoothly.
Of course, during play, preview, or frameserving, all frames are shown. For an explanation, read Doom9's article on Aspect Ratios. When a video is displayed that has a frame size that will not fit on a x desktop, the video is reduced in size by a factor of two. Thus, high-definition HD videos can be previewed without requiring scrolling.
When doing Save Project, Save Project and Demux Video, or Preview, the operation will be applied only to the portion of the timeline between the selected start and end points.
By default, the entire timeline is automatically selected. When no file is loaded DGIndex can display a splash screen. To enable this feature, place an appropriately sized windows BMP file called "dgindex. The Information Panel displays important statistics about the loaded video and audio stream s.
Information displayed in this panel is often essential for correctly processing DGIndex projects, especially when frameserving into third-party applications.
Frame Size - Displays the size of the frame in the currently displayed video. Display Size - Displays the display size of the frame in the currently displayed video. Frame Rate - Displays the playback frame rate of the currently loaded video. Video Type - If the stream does not contain pulldown flags, this field will display "PAL" if the frame rate is If pulldown flags are present, this field will show a percentage "Film" or a percentage "Video" value.
Frame Struct - Displays Frame or Field depending on whether the frame is encoded as a frame picture or field pictures. Please be aware that this merely describes how the frame was encoded; it says nothing about whether the content of the frame is progressive or interlaced. It is common for progressive video to be encoded as interlaced, and vice versa. Note that if a frame is displayed with pulldown, the frame may have been assembled from two pictures with different coding types.
In this case, the coding type of the latest decoded picture that makes up the frame is displayed. To view the coding types without this complication, set Ignore Pulldown Flags in the Video menu. Colorimetry - Displays the colorimetry scheme used by the stream. Field Order - Displays Top or Bottom depending on the field order of the currently loaded video. This number can be greater than the Coded if pulldown is present and the Honor Pulldown Flags option is selected. If the Ignore Pulldown Flags option is selected, this field is not incremented.
It is valid only for vob files. Bitrate - Displays a windowed video bitrate averaged over the last 30 displayed frames. Bitrate Avg - Displays the video bitrate averaged over all the displayed frames.
Bitrate Max - Displays the maximum video bitrate encountered over all the displayed frames. Audio Section Table of Contents Tracks list box - Displays the detected audio id's and corresponding track information. Timestamp - Displays the timestamp for the current position in the audio stream. Remain - Displays the time remaining for completion of the current Save Project, Play, or Preview operation. Note that this may not match the video frame rate of the stream, because the user can configure the playback speed.
Info - Displays video and audio error information. Normal users need not concern themselves with this information, as it is intended for developers and power users. There are three sections to all D2V files: 1 the header section, 2 the settings section, and 3 the data section.
These sections are described below. This number is checked by DGDecode and must match the version expected. Sometimes one forgets that one has an older version in the Avisynth plugins folder, or one forgets to upgrade DGDecode when upgrading DGIndex. The second line gives the number of video files included in the D2V project file.
Each video file must be referenced on the subsequent line s. The header section must then terminate with a blank line. Each source file reference consists of either a filename, if the Use Full Paths option is disabled; or the full absolute path of the referenced file, if the Use Full Paths option is enabled.
If the Use Full Paths option is enabled and the referenced files are moved after creation of the D2V file, you must either edit the paths to be correct, or you must regenerate your D2V file. In the remainder of the D2V file, the files are referenced with a number corresponding to their place in this list. The list is zero-based, that is, the first file is numbered 0.
It was left as "Clipping" in the D2V file to avoid having to increment the D2V file format version number and cause incompatibilities with existing third-party applications. All of these fields must be explicitly defined, even if the associated value is zero. The settings section also must terminate with a blank line. The following table describes each of these parameters and the range of values possible for each.
Each line describes that I picture as well as all the following pictures up to, but not including, the next I picture. Each I picture line consists of eight fields that must be explicitly defined, even if the associated value is zero. The layout for each line is as follows:. The following section describes each field of an I picture line and its range of possible values.
The file field references the file as defined in the beginning of the D2V file containing this line's pictures. The position field is a decimal number that points to the byte position in the source file at which decoding of the indexed I picture should begin.
For non-packetized streams, if a sequence header is present it is indexed, otherwise the picture header is indexed. Packetized streams are treated the same way except that the packet header start code preceding the sequence header or picture header is indexed.
We prefer to index sequence headers because they may carry new quant matrices, but they are not mandatory at each GOP, so we fall back to the picture header. The skip field defines how many I frames to skip to reach the one actually needed.
This is required because an indexed unit especially packs can contain multiple I frames. If nothing were done, we would have multiple D2V file index lines with the same position and DGDecode would not have enough information to implement random access properly.

As a matter of fact, the value of a dynamic dataset lies not only in its content, but also in its evolution history, which in some applications e.
The change detection functionality of D2V allows remote users and curators to identify changes, even if they have no access to the actual change process. Fixed a bug in INI file loading that caused some parameters to be read incorrectly.
Revised the track selection interface to be more user friendly. Added support for frame repeats. These are increasingly being found in P streams. Added two new fields to the info dialog: number of frame repeats, and number of field repeats. The Correct Field Order option is removed and the field order correction function is now available through the Tools menu. A first attempt has been made to add a progress percentage field to the DGIndex window title bar.
Adding checking for audio file names to not be already open in another application before trying to demux to them. Added a new tool in the Tools menu: Analyze Sync. Revised the indexing code to support the case where an indexed unit especially packs might contain more than one I frame. Previously random navigation in DGDecode failed for this rare scenario. Fixed a bug that caused DGIndex to sometimes use colorimetry in the preview window and when doing Save BMP when should have been used.
The Info Dialog was correct, however. Audio-only demuxing of LPCM audio was fixed. Making a range that cuts from the start failed for some program streams. Note that the raw PCM is demuxed same as xport. You must use an audio processor, such as sox. PID detection and the Info dialog are supported for this new audio type. Thanks to drmpeg for showing the way with xport.
Added a warning pop-up to notify the user that a field order transition was detected. For streams that specify as the vertical height for both the encoded and display sizes, a pop-up appears once on file loading not done for CLI invocation asking if the video should be treated as if it has a height of Syntactically, it now a correctly handles sections that cross transport packet boundaries, or that start in the middle of a transport packet following a previous section, b correctly handles streams with multiple PAT sections, and c correctly handles streams that put all the program information on one PMT PID.
The parser is now fully correct syntactically. Semantically, it now a correctly labels private stream video, b labels all scrambled streams so that user can avoid crashing DGIndex by selecting a scrambled stream, and c properly distinguishes between AC3 audio streams and Teletext streams. Fixed a problem with playback speed control. DGIndex now supports "Open With" operation.
Or you have a shortcut to DGIndex on your desktop and then highlight a bunch of VOBs and drop them all on the shortcut; they are opened in sorted order.
It always irritated me that you couldn't do that. This happens when a new file is opened with the PIDs set to reserved 0x Thereafter, the Set PIDs dialog is controlling.
A new option under the file menu was added: Demux Audio Only. This is intended for demuxing the audio from streams that do not contain video. Made transport stream detection more robust 3. The Parse D2V log now includes the running time of the video. The quants log now includes the frame numbers at which the matrices appear. Fixed garbage in file list caused when hitting the Up button with an empty list. Added a new option called Use Full Paths. When enabled, behavior is as it always has been.
When disabled, only file names not full paths are used as references in the D2V and generated AVS files. This makes it easier to move project files.
This new option was contributed by Christian Eberl. Thank you, Chris! Changed the exception handling in DGIndex. Previously an exception would abort the entire preview or save project operation. Now only the current picture decoding is aborted.
Added an option to force proper parsing of audio when the stream is not DVD-structured i. Fixed problem that made it impossible to demux MPEG1 video from transport streams. Fixed a problem that caused a long delay before a play or preview operation begins for some transport streams. Fixed a bug in indexing for some field structure streams. The D2V file format version number was bumped to This should have been done for version 1. Fixed a problem in DGDecode that could cause a lockup when navigating on the timeline with some unusual field structure streams.
Increased the maximum number of input files from to This way, e. DGIndex was actually getting the framerate correct, but when it wrote the d2v file, it would multiply the floating point value up by and then save it.
Then DGDecode would use that value for the numerator and for the denominator. Then in the d2v file it writes, e. DGDecode then uses those values when setting the frame rate in Avisynth. This change bumps the D2V file format version number to The message box that pops up for transport streams when no data is found has been clarified to direct the user to use the Stream menu to set the PIDs. The DGIndex Information dialog now shows an overall average bitrate for the entire previewed video in addition to the windowed value.
The windowed value now reports every 32 frames instead of every 64 frames. DGVfapi's handling of audio from avisynth scripts was fixed. It didn't set values for dwBlockAlign and dwReadedSampleCount, and it should be converting the output to bit integer if it isn't already in that format.
Refer to the manual for details. Fixed truncation of last few bytes of the demuxed M2V file. It should now be possible to open up to files at once via the open dialog. Fixed major bug in random access when multiple elementary streams are loaded. If a CLI D2V creation is invoked on a transport stream with the wrong pids specified, when you enter the right PIDs, a bug caused an invalid filename to be generated for the D2V file ". This has been repaired.
Refer to the DGIndex manual for details. A complete and definitive account of the undocumented audio options was added to the DGIndex user manual. I hope it may dispel some confusion and misconceptions. Added "m1v" to the open dialog "Files of type" string.
Fix D2V is now run automatically and the D2V file is repaired. See the reference manual for details. Colorimetry was reported incorrectly for MPEG2 in some cases. This has been fixed. Fixed improper handling of the right arrow button. Fixed broken Load Project functionality Version 1.
You can, for example, specify tracks 1 and 3 for demuxing. Previously, you could choose one track or all tracks. Added quant matrix logging. 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.
Fixes for bugs in YV12 upsampling tritical.
