DGMPGDec 1.4.1 Release Candidate 2

Posted on Friday, August 26 2005 @ 01:02:08 CEST by LSDsmurf

This release provides the following changes compared to version 1.4.0:

1. DGDecode's fastMC option is enabled for 3dNow.

2. A scanning bug in reading the D2V file in DGDecode has been repaired.

3. The track specification for GUI and CLI has been changed to allow multiple tracks to be enabled for demuxing. You can, for example, specify tracks 1 and 3 for demuxing. Previously, you could choose one track or all tracks.

4. Added the Skal and Simple IDCTs from DGDecode to DGIndex.

5. Added quant matrix logging.

6. Revised the video error handling to prevent macroblocking in some error cases, and to prevent incorrect frame delivery leading to AV desync in some error cases.

7. A default save file name is now set in the Save Project dialog.

8. The CLI now supports demuxing the video (-OFD).

9. Fixes for bugs in YV12 upsampling (tritical).

10. When repeat flags are present give Film/Video percentages instead of FILM/NTSC percentages. This avoids showing a PAL as NTSC in some cases!

11. The command line buffer has been increased to 4096 bytes. If you use a DOS shell instead of programmatic invocation, you will be limited by the capability of the DOS shell.

12. Destroy the Info dialog window upon any of these events: new file(s) opened, right/left arrow buttons hit, scroll operation on timeline.

13. Various changes/fixes for upsampling by tritical. These apply as appropriate for DGDecode, DGIndex, and DGVfapi:

  • upConv can now be set to 3 values: 0, 1, and 2. 0 = do nothing, 1 = YUY2 output, 2 = RGB24 output... for the case that the input is 4:2:2 then 1 is the same as 0.
  • Added iCC parameter. iCC=true uses interlaced YV12->YUY2 upsampling, iCC=false uses progressive YV12->YUY2 upsampling, and leaving iCC unset makes it switch based on the progressive_frame flag.
  • Fixed a little problem with the 422->444 conversion, fixed a problem with the 444->RGB24 conversion where it wasn't correctly handling pixel values that came out as < 0, and added a faster isse 422->444 conversion. I also modified the 444->RGB24 conversion so that it uses the correct coefficients (indicated by the matrix_coefficients value).
  • Added a way to force DGVfapi (and the DLL access functions) to follow the progressive_frame flag.
  • Added a Colorimetry box to the DGIndex Info dialog.
14. Top-level picture decoding (slice and macroblock layers) was completely redesigned to dramatically improve resilience to video errors, and to correct some spurious video errors due to bugs in the old approach. The previous design is a legacy of the original MSSG reference decoder. The new design was adapted from fccHandler's excellent VirtualDub MPEG2.

15. Modified the Info dialog display of video errors to show text reasons instead of numbers.

16. Added "fccHandler" to the credits listing in the DGDecode manual.

17. Revised the playback speed option. It now gives 5 checkable options: super slow (5fps), slow (10fps), normal (plays reliably at the correct frame rate for the stream), fast (2 times normal), maximum (as fast as possible).

18. A warning box is popped up if Force Film is used inappropriately. The user can decide whether to proceed anyway or to cancel.

19. The leading number on the file path lines at the top of the file was eliminated. This makes editing the D2V file to change paths easier. The D2V file format version is therefore bumped to 11, and you will need to remake existing projects.

20. Added a "Force Open GOPs in D2V File" item to the Option menu.
