DGMPGDec 1.5.3 Final

[Guest]

* Pop-up warning message boxes are now suppressed for CLI operation.

* PSIP PID detection has been added.

* PIDs are now displayed in decimal as well as hexadecimal.

* A new option, Looped Playback, was added. When the end of the timeline is reached during a Play or Preview operation, playback is automatically restarted at the beginning of the timeline.

* A bug was fixed in the transport packet length detection code. This caused some M2TS streams to be parsed incorrectly.

* The file type .m2t was added to the open dialog.

* Some array sizes were increased to prevent crashes in the debugger.

* The next_start_code() function was enhanced to add error resiliency for abnormal slice terminations.

* Because the code never writes to the DirectDraw surface anymore (removed long ago!), the DirectDraw Overlay option was removed. DGIndex now never seizes the overlay.

* When the Use Full Paths option is turned off, relative paths are used. This allows for the source files to be in a different directory than the D2V file. If they are in the same directory, the behavior is the same as before.

* In CLI mode, if a field order transition is detected, it is silently corrected.

* Fixed two problems with .m2ts files: 1) audio on PRIVATE_STREAM_1 was not processed correctly, and 2) video demuxing was broken.

* Fixed a problem that resulted in an abort of processing with the message box popup "Force film mode is not supported with frame repeats".

* Removed the limitation that the AVS and D2V files must be in the same directory when the Use Full Paths option is disabled. Thanks to Rainy for showing the way.

* 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.

* The infamous GOP warning popup has been removed. The D2V Parse log now shows the open/closed status of the GOPs, so if you need to know if your opening GOP is open, look there.

* The Info dialog position is no longer pegged to the main DGIndex window. It can be independently positioned and its position is saved and restored via the INI file. Also, its font size has been decreased and all the group boxes are now arranged vertically.

* An option was added to control how HD videos are displayed. You can now shrink by half (the previous behavior) or you can view any quadrant of the video. This allows the interlace structure of HD videos to be inspected.

* Fixed a problem that caused DGIndex to miss some audio streams. For example, if AC3 substream 0x80 was present, and MPA stream 0xC0 was present, both would be viewed as Track 1, and only the first one encountered would be detected. The concept of track number is removed (as it is a DVD-specific construct), and it is replaced with the concept of audio id. See the users manual for details.

* For MPEG audio streams, the Info dialog now shows full information: audio id, layer, number of channels, sampling rate, and bitrate. This information is also included in the filename of demuxed MPEG audio streams.

* Whenever the Info dialog is closed, a log file is (optionally) created that contains the same information. This may be invoked by the CLI to silently query the nature of the input file. Please see the users manual for details.

* When a stream does not declare the colorimetry, matrix_coefficients=1 is assumed for HD video and matrix_coefficients=5 is assumed for SD video.

* Fixed a bug that caused automatic PID setting for transport streams to use the last audio stream encountered instead of the first.

* Added an MRU list to the File menu.

* 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.

* 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.

* The Info display now shows the picture coding type (I/P/B).

* Added a maximum bitrate field to the Info display.

* Demuxed MPEG audio files are now given the extension mp1/mp2/mp3 depending on the audio layer. The old behavior can be enabled via an INI file option (see users manual).

* Transport packet resync and M2TS file detection were made more robust.

* Fixed a bug in the Log Timestamps function, whereby a video DTS value was incorrectly shown as a PTS value.

* Fixed a bug in demuxing of DTS audio from transport streams.

* The aspect ratio field of the Info dialog now shows the raw value of the field as well as the corresponding string.

* The display size from a sequence_display_extension is now shown in the Info dialog. This, together with the change above, allows the sample aspect ratio (SAR) to be inferred, according to the MPEG2 specification.

* A default path for saving BMPs can now be specified.

* Fixed a bug whereby tracks selected for demuxing in the INI file were not actually enabled for demuxing until the track selection dialog was saved. Now they are honored on startup as they should be.

* Fixed the CLI to also parse for the = sign at the end of the options to avoid false option detection. E.g., the substring '-aif' anywhere in a file name would be parsed as an option specification.

* Other miscellaneous CLI parsing bugs fixed.

* When doing a preview via the CLI, the playback speed is set to maximum.

* When a Play/Preview/Save Project Operation begins, the focus is now left on the main window. Previously, it annoyingly moved to the Info window.

* Don't check for field order transitions for streams with only frame repeats.

* Use lowest numbered audio ID to expand __aud__ instead of the first audio stream encountered in the source files.

* Fix parsing with log timestamps enabled.

* Correct handling of default matrix coefficients for hints.

* Add option for beeping and focusing when save project finishes.

* Save BMP is now enabled during play/preview.

* Fix regression in transport stream detection.

* The Full Paths option is now honored for CLI invocation.

* Fixed the audio delay calculation, timestamps dump, and analyze sync tool for streams that do not contain GOP headers.

* The analyze sync tool now prompts for the audio ID instead of a track number.

* Fixed incorrect audio demuxing when demuxing audio only.

* Fixed display of field order for field structure streams.

* Fixed bug: Open file, Save Project, then File -> Open -> OK gives an error messge.

* Fixed bug: Save project with decode AC3 to WAV. Repeat that. Each time the WAV file becomes longer. The size was not reset to zero.

* Fixed a problem that caused some program streams to be detected as transport streams.

* Fixed a problem with video demuxing that sometimes caused an extra partial first GOP to be demuxed at the start of the stream.

* Added mousewheel support.

* Added a -RG option to the CLI (define project range).
