A very, very important app in the free video community -- this is the basis of such other apps as AutoGK. Without this program (and DVD2AVI), the free video community would be a whole lot poorer. For that reason, it's hard to rate. I did put functionality as an 8, since it's weak in some of its functions like downmixing to .wav format.
DGMPGDec consists of two files that go together: DGIndex.exe and DGDecode.dll. The version of the two files should always be the same, you can't mix and match.
What DGIndex does is loads an unencrypted DVD movie (VOB files) and allows you to create an index (.d2v) of the frames in that file, as well as demultiplexing the audio to separate files (if you wish).
DGDecode.dll uses that .d2v file to decode the MPEG2 video from the DVD. A third-party app like AVISynth is required to make use of the .dll in order to do something with the decoded video. Typically, you load it in an AVISynth script and then AVISynth frameserves the video to another program like VirtualDub so you can actually do something useful with it (like convert to DivX or whatever).
Very, very useful program and very underrated as well. Most people aren't aware of this program being at the heart of many freeware video apps. |
