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.
