- DGFix 1.0.0

-
- DGFix is a command line program that corrects illegal D2V files.
- Due either to bugs in software or to malformed streams, it is
- possible to encounter D2V files that have illegal flag
- sequences, such that a request is made for two consecutive
- top or bottom fields. Top and bottom fields must strictly
- alternate! When such an illegal transition occurs, the
- Avisynth mpeg2source() filter (and other decoders that read
- the D2V file) will generate field inverted video from the point
- of error (and until a subsequent illegal transition cancels
- the first one!). When you view the clip, the field order appears
- to change at the illegal transition.
-
- Standalone and some software players are able to ignore/correct
- the illegal requests on the fly, but currently DGMPGDec
- cannot. Therefore, this program can be used to fix the D2V file
- before it is sourced into mpeg2source().
-
- This program works with DGMPGDec version 1.0.0.
-
- Usage: To use the program, type:
-
- dgfix file.d2v
-
- The program will create a fixed D2V file called file.d2v.fixed.
- The program will report the errors and corrections to the
- command window.
