DGDecNV: CUDA-basierter Multi-Decoder für AviSynth

DGDecNV Build 2007 haben wir bereits übersprungen... dank einheitlicher CUDA-Unterstützung sind MPEG2- und MPEG4-AVC-Decoder mittlerweile in DGMultiSource() vereint.

Nun gibt es DGDecNV Build 2008:

Zitat

* Redesigned the SPS/PPS heuristics for AVC streams in DGIndexNV. This fixes cases of bad decoding when navigating on the timeline for streams that: 1) Have SPS/PPS's remote from the seek point. 2) Re-use SPS/PPS IDs for NALUs with different content. The fix dramatically improves things for such streams, but it may not be perfect because it is, after all, a heuristic. Note that this problem did not affect serving video through the Avisynth script; it affected only navigating the timeline in DGIndexNV (but see below).

* The SPS/PPS heuristics fix also fixes bad video demuxing for the same cases described above.

* Added tooltips for the navigation buttons and navigation bar in DGIndexNV.

* Fixed a problem that caused the DGIndexNV GUI and the DGI file to disagree about the frame size in some rare cases.

* The Detect PIDs dialog now shows the PIDs in both decimal and hexadecimal.

* The Quick Start guide was revised to use DGMultiSource() by default. A second Quick Start guide is provided for DGSource()/CUVID Server usage.

Außerdem wurde DGAVCDec von Donald Graft's Website entfernt... eine Wiederauferstehung wird es wohl erst geben, wenn klar ist, ob DiAVC als Ersatz-Decoder für libavcodec implementiert wird.

DGDecNV 2009

DGDecNV 2010

Zitat von Donald Graft

* The previously hidden transport stream trim functionality is now exposed in
the GUI. A progress dialog for the trim operation has been added. Performance of the
file write operation has been improved. The functionality is now more robust for
writing proper packet boundaries. 192 byte transport packet streams are now
properly supported. Refer to the users manual for important usage notes and
caveats.

* Added a CLI avs template command: -at file.

* Fixed the Disable Display function for double rate deinterlacing. The operation
of this function has been made more robust.

* Fixed a problem causing some AAC streams to not be detected.

* Fixed a problem causing some teletext streams to be detected as audio.

* Added an error popup for non-4:2:0 streams (until supported by Nvidia).

* Fixed a problem in indexing of MPEG2 streams that caused some unusual but legal
GOPs to be considered malformed and cause an abort of the indexing.

DGDecNV Build 2011 -- jetzt auch mit 64-bit-Version!

Zitat

* The DGI file format version was bumped to NV6. So remake your projects
and INI files.

* NV12 to RGB code in DGIndexNV was converted to pure C for x64 compatibility.

* The PC/TV Scale option was removed. In the DGIndexNV display, PC scale is always used.
This affects only the display in DGIndexNV, and has no effect on video served by
your scripts.

* The Detected SIMD option was removed as there is now no asm code.

* An autocrop function was added to the cropping dialog.

* Fixed a problem causing spurious audio tracks to be demuxed.

* Fixed a problem with timeline navigation in DGIndexNV for some MKV files.

* Fixed a problem with AVC streams with 16 refs.

* Fixed a problem with sequence headers not being processed in some cases. This could
result in the frame rate not being correctly detected.

* Inlined a lot of the parsing code to improve indexing performance.

* Fixed a problem that caused some scripts to take a long time to be opened.

* Implemented 64-bit binaries (for power users only).

DGDecNV Build 2012

Zitat

* Fixed a problem that could cause the source filters to hang if the last picture
in the stream is incomplete (due to bad editing).

* Implemented film % detection for AVC video.

* Silently ignore leading frames that are missing their required SPS/PPS's.

* Fix a problem that caused AVC sequence extensions to be reported as illegal
NALUs.

* Fix a problem that caused seeking on the timeline in DGIndexNV to report
failure to create the video decoder for some low-end NV cards.

DGDecNV Build 2013 -- neue Lizensierung, neue Verschlüsselung!

Zitat

I'm about to cut over to my new generation security:

* Asymmetric key encryption using RSA to kill serial gens.
* Various anti exe-cracking strategems.

When the cutover occurs, the license generator will generate only licenses for version 2013 and greater, which will be released at the same time. I will reset all license counts to 0 so that you can get licensed for versions going forward.

The license generator will be disabled for a short period during the cutover.

My previous "security" was laughably weak.

DGDecNV Build 2014

Zitat von neuron2

* Added support for BluRay MPLS playlists.

Huch, das geht ja wie's Brezelbacken...

Build 2015

Zitat

* I got too clever by half with my licensing check in an attempt to punish people using patched executables. It wasn't working right, however, causing it to emit some bad frames even for good licenses in some (not all) cases. I won't try anything like that again. :eek: Now, if you don't see your video you have to remake your license. I'm done with this nonsense. It's not a battle I can win. Do not use 2014! 2013 is OK.

* Here's a cookie to make up for the first item above. Added audio language detection for opened MPLS files. After opening the MPLS file, Audio/Audio Demux will tell you the languages of the (nonhidden) streams.

Build 2016

Zitat

My latest anti-cracking strategy: a new release every day.

* Fixed a bug in VC1 pulldown detection. For example, streams on the bluray "Life" were being erroneously marked with frame pulldown in the DGI file, causing extra frames when serving.

* Bumped the DGI version number to 8 to complete the removal of the ill-advised protection. (Yes, tormento, I know you hate me.)

__

Build 2017

Zitat

* In the file list dialog, if no changes have been made, hitting OK now does
not reopen the input files.

* A File/Step option was added. When the display is set to full size, on some
displays the buttons are off screen. This change allows the single-step mode to
be entered in such cases.

* Fixed crashes when a bare MPLS file is opened (one not part of a full BDMV tree).

* Opening files with CLI -i -o failed with small files. Fixed.

* Fixed two bugs in video demux: 1) garbage before the first start code was erroneously
replaced with zeroes instead of being deleted, 2) for AVC, trailing_zero_bytes greater than 1
resulted in writing garbage at the end of the NALU, making the demuxed file unusable.

* DGI file format is unchanged and working licenses continue to work.

Licenses will continue working going forward from 2015.

I plan to reset everybody's license count to 0.

Build 2018

Zitat

Keeping those crackers on their toes!

* Fixed case of recovery point SEI appearing before the PPS. This fixes AVC streams cut with VideoRedo.

http://neuron2.net/dgdecnv/dgdecnv.html

P.S.: Im Moment wird offenbar ganz heftig an der Disk-Performance geschraubt. Und offenbar verhalten sich da verschiedene Windows-Versionen recht unterschiedlich. Unter XP war zwischen C- und Low-Level-Zugriffen eine Steigerung auf die 3...4-fache Geschwindigkeit möglich.

Build 2019

Zitat

* Made license switching a bit more convenient. Previously if you opened
a stream with the wrong license selected, then set the correct license, and then
did File/Open followed by OK with the intent of reopening the file, the file would
not be reopened because no change was made to the file list. Now any change in
the selected license will be treated as if the file list was changed, and the
input files will be reopened.

* The initial window position for DGIndexNV stored in the INI file was not being
honored. Fixed.

* Added an auxiliary INI file option to avoid a popup when there is a mismatch
between the PAT/PMT audio type and the actual detected audio type. Delete your
old INI file to allow DGIndexNV to create a new one with the option.

* Improved the heuristics for SPS/PPS injection for MKV streams.

* Performance improvements for indexing on many systems. The improvement is
substantial on most WinXP systems. The large pauses during playback in DGIndexNV
also now do not occur.

* Fixed the remaining time display in the Info dialog so that it properly
honors the configured project range.

* Added a timestamps dump function under the Options menu. This will dump the
STC/PCR, PTS, and DTS timestamps for the video and audio streams in a transport
or program stream.

* Fixed a bug that manifested as follows for some MKV files: Open the MKV file.
Hit preview/play. Hit stop. Hit preview/play again. DGIndexNV hangs.

Build 2020

Zitat

* Revised DGMultiSource() to use floating CUVID contexts so that it no longer leaks GPU memory.
This should enable use in all GUIs without the dreaded decoder creation failure or crashes.

* Due to the fix above, CUVID Server and DGSource() are no longer necessary
and are therefore retired and omitted from the distribution.

* Added an error popup for VC1 streams that erroneously contain sequence headers
not followed by an I frame (as required by spec). If you run into this please let me
know.

* Fixed a regression in pulldown detection for VC1.

* For AVC, POCs are now stored in the DGI file as they appear in the stream, i.e., they
are not divided by two.

* Fixed a regression in expansion of the __aud__ and __del__ macros for script generation.

Build 2021

Zitat

* Save BMP and Copy Frame to Clipboard now save the original frame size (with cropping honored).
Previously, if the frame was reduced by half for display, the reduced frame size was saved/copied.
Now the saved frame will accurately represent what will be served via your script.

* Corrected NV12 to RGB conversion based on the matrix coefficients (for the 32-bit version only).

* Fixed the following bug: Enter single-step mode, minimize the window, and then restore the window;
DGIndexNV hangs.

* The Help menu is now not disabled during play/preview/indexing.

* Reduced GDI load from updating the trackbar.

* Fixed a bug in the program stream parser that could cause play/preview/indexing to fail.

* DGSource() and DGMultiSource() are now synonyms. The Avisynth source filter is named DGDecodeNV.dll.

Build 2022

Zitat

* The DGI file format is bumped to NV9.

* The crappy luma filter was removed.

* NV12->RGB24 conversion for display is now executed on the GPU. This improves the
display rate in DGIndexNV and makes the code common for 32-bit and 64-bit versions.

* DGIndexNV now accepts a license file without a carriage return.

* The AlwaysCrop and AlwaysCancelOnAudioMismatch options are now exposed in the
GUI Options pulldown.

* The license file can now store multiple license numbers. The License Switcher
is therefore now unnecessary and was removed.

Build 2025

Zitat

* Fixed a GUI bug that could cause the first frame to be displayed wrong just once on
initial open in DGIndexNV.

* Fixed missing detection of audio streams with stream_id 0xbd when PAT/PMT is not present.

* Fixed the broken CLI option -od (save project and demux video).

http://neuron2.net/dgdecnv/dgdecnv.html

Build 2026

Zitat

* Fixed a race condition between CUDA init and filter deinstantiation that could cause
a crash when DGDecodeNV is instantiated and then deinstantiated without a call
to GetFrame(). Some third-party applications do that to get the video clip properties
returned by an Avisynth script.

Build 2027

Zitat

* Fixed a problem that caused some 192-byte-packet transport streams to be detected as 188-byte.

* Fixed a problem that caused some transport streams to be reported as missing video data.

* Added a check to the Enable PureVideo Deinterlacer parent menu item to make it easier to see when you have deinterlacing enabled.

DGDecNV 2029 [Oct 05, 2010]

Zitat

Build 2029
----------

* If multiple files are loaded in DGIndexNV and one of them contains an end of stream
NALU, then indexing would stop at that point, truncating the entire file set. Fixed by
ignoring end of stream NALUs.

* Fixed the Info dialog frame type field for AVC field-structured streams. Frames with structure
I-P were erroneously displayed as P frames rather than I frames.

DGDecNV 2030 [Oct 07, 2010]

Zitat

Build 2030
----------

* Fixed a problem that could cause macroblocking and/or decode warning popups in DGIndexNV
for MPEG2 program streams when scrolling on the timeline.

DGDecNV 2031 [Oct 08, 2010]

Zitat

Build 2031
----------

* Fixed a problem with GOP stepping (especially backward) on the timeline in DGIndexNV.

* Fixed this problem: If you single-stepped into the end of the file, then subsequent play
or stepping would malfunction.

DGDecNV 2032 [Oct 10, 2010]

Zitat

Build 2032
----------

* For MPEG2 streams, DGDecodeNV now automatically includes hinting data for ColorMatrix().

DGDecNV 2033 [Oct 13, 2010]

Zitat

Build 2033
----------

* Added ability to specify the GPU device to be used when more than one is present. A new
dialog was added to the Options pulldown that lists the available GPU devices.

* Fixed demuxing of TrueHD audio and added display of TrueHD stream info.

* Fixed a problem of clearing all data when an AVC file is closed. It could cause a subsequent
AVC file open without exiting DGIndexNV to fail.

* The index file format was bumped to NV11.

Also neu indexieren!

DGDecNV 2035 [Oct 26, 2010]

Zitat

Build 2035
----------

* Fixed an issue where a long stretch without video packets in a transport stream could cause
a failure with a "Cannot find video data" error popup.

* Added a textual debug overlay option to DGDecodeNV that (currently) can be used to display
the filter version, the GOP number, the display and coded frame numbers, and the frame coding type.
