- DVD2AVIdg/MPEG2DEC3dg Functional Changes
- (versus DVD2AVI 1.77.3 original and MPEG2DEC3 1.10 [Nic])
- ---------------------------------------------------------
-
- DVD2AVIdg/MPEG2DEC3dg Version 1.0.0
-
- 1. Frames are no longer lost at the beginning and end of the
- delivered video. If the first frames in display order are B frames
- they are now delivered, whereas previously they were discarded.
- If initial B frames are decodable (closed_gop = true), they are
- displayed as decoded; if they are not decodable (closed_gop = false),
- they are replaced with copies of the first decodable frame.
-
- This is the most important fix and is the real motivation for this
- entire development. The frame loss causes serious problems in some
- authoring applications.
-
- 2. To allow for the delivery of the initial B frames when IBBP...
- GOPs are decoded (see 1 above), the audio delay is adjusted
- appropriately.
-
- 3. Random access using MPEG2DEC3dg is now fully correct. Previously,
- if you navigated to a frame that corresponded to an initial displayable
- B frame in a GOP, you would actually get the first subsequent I frame,
- which is typically several frames later.
-
- 4. If the first GOP has non-decodable B frames first in display order,
- DVD2AVIdg pops up a warning message box to alert the user. This popup
- is suppressed when DVD2AVIdg is used in automatic mode from the command
- line.
-
- 5. Command line support was added to enable other applications to
- invoke DVD2AVIdg without user involvement.
-
- 6. DVD2AVIdg adds the capability to read either 1.76-style or 1.77.3-style
- D2V files. It also adds the capability of saving the project in either
- format.
-
- 7. Auto increment on file names now works in a more general fashion. The
- rule is now that the file name is scanned from the end toward the beginning
- until an _ character is found. Then the (possibly multidigit) number
- following the _ character is incremented. This allows for proper auto
- increment for file names such as:
-
- VTS_02_1 - 0xE0 - Video - MPEG-2 - 720x576 (PAL) - 16~9 - Letterboxed.M2V
-
- 8. The command line -IF and -AIF options no longer require full path names.
- If the specifier does not include a path, the current directory is used.
-
- 9. If the command line -OF file cannot be opened for writing, DVD2AVIdg
- does not crash. If a valid -OF file is given without an -IF or -AIF file,
- DVD2AVIdg does not hang.
-
- 10. A VFAPI plugin is provided that supports these fixes. Note that these
- fixes do not fully apply when DVD2AVI's Save AVI and Preview features are
- used. That may be corrected in a future version but don't hold your breath
- while waiting for it.
