It can be used to decode MPEG2 streams from DVD VOBs, captured transport streams, .MPG .MPEG2/.M2V files...
Changes in DGMPGDec 1.5.0 RC :
- Fixed a regression in RC1 for field structured streams that could cause a hang in DGDecode.
- The Info display now shows the picture coding type (I/P/B).
- Added an option to enable/disable the automatic log file generation (default is enabled).
- Added a maximum bitrate field to the Info display.
- Leading B frames for field structure streams were not counted correctly, causing a possibility to display bad starting frames when serving with DGDecode. Fixed.
- Fixed possible crashes when exiting DGIndex while a play/preview is in progress.
- DGIndex no longer beeps and brings its window to the foreground when a Save Project operation is complete.
- Fixed minor bugs in the MRU list handling.
- The quants displayed by DGDecode's showQ=true did not match the avg/min/max values displayed for info=1 (the showQ display was not re-ordered for display order). Fixed.
- Only half a screenful of values were shown with showQ=true for field structure streams.
- The funny transparency for the showQ display was fixed.
Changes from DGMPGDec 1.4.8 to DGMPGDec 1.4.9 :
- Added checks for extra robustness against emulated audio start codes for MPEG audio in program streams. This fixes some known streams with emulated audio start codes.
- Made AC3 parsing more robust by making audio data less likely to erroneously
emulate a sync byte. Rare AC3 streams that couldn't be parsed are now handled correctly.
- Changed the running time line at the bottom of the Parse D2V output so that it now
includes fractions of a second.
- Added additional MPEG syntax error checking to improve the robustness and error recovery.
This fixes one reported stream that showed excessive macroblocking on one type of syntax
error due to corruption.
- Fixed an error in random frame access in the presence of RFF flags.
- Added the PCR for transport streams and the SCR for program streams to the
'Log Timestamps' dump.
- DGIndex can now automatically set the PIDs on file open for streams that lack PAT/PMT
tables. If the PAT/PMT tables are absent, DGIndex falls back to using raw PID detection
and sets the first audio and video PIDs seen in the stream.
- The __aud__ variable in the AVS template now uses the first audio track found
instead of the last.
- 204-byte transport packets are now supported.
- The info dialog now includes a stream type field.
- If an exception occurs during processing, a message box pops up and allows the
user to choose to continue or to abort.
- The D2V file version is bumped to 16.
- The AVS template path now defaults to a file called "template.avs" in the same
directory as DGIndex.exe.
- Fixed a bug in INI file loading that caused some parameters to be read incorrectly.
- An error popup now appears if the user attempts to execute "Demux Audio Only" when
the audio method is set to "Decode AC3 Track to WAV".
- Fixed a bug in relative path handling that crashed DGIndex when "Load Project" was performed.
- Revised the track selection interface to be more user friendly.
- Added support for frame repeats. These are increasingly being found in 720P 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.
- When in CLI mode, DGIndex no longer grabs the foreground focus and beeps at the
end of a Save Project operation.
- Fixed a bug in the LumaYV12() filter (part of DGDecode) that could cause a
crash in some circumstances.
- 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 601 colorimetry in the preview window
and when doing Save BMP when 709 should have been used. The Info Dialog was correct, however.
- Added support for M2TS (Blueray Disk MPEG2) files.
- The reporting of matrix coefficients was off by one GOP so if they changed,
one GOP would be reported wrongly. Fixed.
- Multiple __vid__ and __aud__ per line are now supported in AVS template files.
- Audio-only demuxing of LPCM audio was fixed.
- Making a range that cuts from the start failed for some program streams. Fixed.
- Added support for demuxing LPCM from M2TS (Blu-Ray) files. Note that the raw PCM
is demuxed (same as xport.exe). You must use an audio processor, such as sox.exe,
to repackage it as you want it (typically as a WAV file). Refer to the DGIndex Users Manual
for instructions in that regard (Audio/Output Method section). PID detection and the
Info dialog are supported for this new audio type. Thanks to drmpeg for showing the way
with xport.exe.
- Added a warning pop-up to notify the user that a field order transition was detected.
