This version fixes decode issues. All but one of the streams previously provided now work, and that one was corrupted, I believe.
As described in the help file, the last several frames of the BBC streams may be incorrect. I am working on it.
Note that you have to replace all the DLLs (avcodec-51.dll, avformat-51.dll, avutil-49.dll), even though their names have not changed. I am still working on a better solution. The easiest thing to do is to put them in \windows\system32 or somewhere else on your DLL search path. If you can't, the help file points you to an alternate solution.

DGAVCDec 1.0.0 Alpha 5
Neueste Version. Leider weiß er selber nicht mehr, was er alles verändert hat. 
Man kann jetzt aber "Save BMP" und "AVS Template" nutzen. Außerdem stürzt DGAVCIndex nicht mehr ab, wenn es minimiert (gestartet) wird.
Aber anscheinend noch keine Commandline. 
* Fixed broken GOP stepping after play/preview.
* Title bar FPS indication now has three places after the decimal point.
* A "Finished!" popup now appears at the end of the Save Project operation.
* Fixed an uninitialized variable in DGAVCDecode that could cause crashes in some circumstances.
* Redesigned the whole decoder DLL situation (read the help text carefully before using alpha 6):
- Now only one decoder DLL is required (libavcodec.dll).
- The decoder DLL is stripped down to include just AVC decoding.
- The decoder DLL must be placed in the same directory as DGAVCIndex.exe. The path is automatically passed to DGAVCDecode.dll in the DGA file.
- The decoder DLL project is buildable in Visual Studio 2005, allowing for direct tracing/debugging.
- The decoder DLL is derived from the ffdshow_tryouts project.I think I'll add transport stream support next, and then tackle PAFF.
Version 1.0.0 alpha 7
Here's a nice shiny new version for y'all:* Indexing is 6 times faster! I knew you'd like that. I ditched the JM Reference code NALU processing and made my own. Their code was doing fgetc() on every byte and was chock full of useless memcpy's and dynamic memory allocation.
* When pulldown flags are seen, the user is offered the chance to force the IVTC'ed frame rate. "Force Film" is not yet implemented, so you need pure telecine throughout for this interim solution to work right.
* In preparation for implementation of "Honor Pulldown Flags" and "Force Film", a new index key was added to the DGA file:
PIC n
...where n is the pic_structure type of the following frame. This is the equivalent of TFF/RFF in MPEG2. Remember that the picture timing SEIs are optional, so don't be surprised if you don't see any in the DGA file.
* The DGA file format version is bumped to 4.
* An MRU list has been added to the File menu.
* It no longer rejects PAFF out of hand, but I haven't yet got it working properly with any version of libavcodec.dll that I can find. Hopefully there will be a working version and it will slot in without further changes.

It ships with my stripped down libavcodec.dll, but you can replace it with any version you like. I'm hoping this version no longer crashes after I recompiled it with VS 2005 SP1.
The changes were extensive, so please pound away.

und Alpha 8 gleich hinterher:
This fixes the timeline navigation problems in alpha 7.
http://neuron2.net/dgavcdec/dgavcdec100a8.zip
Note: Please re-download alpha 8, as I had a little bug in it. Playing until end of file messed up subsequent navigation.
This version adds the Info dialog functionality.
http://neuron2.net/dgavcdec/dgavcdec100a9.zip
One tip: To see the frame types, set the playback speed to Single Step before starting your preview. Otherwise that field is just a blur.
The changes were extensive as I had to implement the parallel parsing I described in my earlier post. So pound on it with relish.
* Lots of GUI bugs and crashing bugs fixed.
* New info window field: max bitrate seen.
* Major code cleanup and purging of DGIndex leftovers. Conversion to exclusive C++ compilation.

Please delete your INI file before running this, or replace it with the one in the zip file.
...
Wir kommen der Sache Schritt für Schritt näher:
* Properly counts each pair of field coded pictures as one frame. Should improve PAFF support.
__
Und noch einer:
* Fixed g0blez's problem with NALU parsing. Transformers now indexes all the way without errors.
* Fixed a problem with random access that caused bad frames to be displayed sometimes. @canTsTop, please advise if this affects your scrolling crashes.
* Preliminary implementation of Honor Pulldown Flags. Note that this affects only the output of DGDecode.dll; the DGAVCIndex display always shows the non-pulled down stream. You can set Honor Pulldown Flags for Transformers and you will see the standard 3-progressive/2-interlaced pattern when viewing the output of your script.
Nach ein paar weiteren Überarbeitungen als a12, hier jetzt die
* Fixed the problem of MeGUI stopping after a first pass when libavcodec reports warnings/errors.
* Fixed some incorrect seeks.
* Added real help files.
* Miscellaneous little bug fixes.
Interessant v.a. die Entdeckung eines Fehlers im Deblocking: libavcodec versuchte auch die linke und obere Kante zu deblocken, obwohl links davon und darüber ja keine Makroblöcke zum Vergleich mehr existieren. Ich hoffe, dieser Hinweis wird bald auch in libavcodec-Versionen einfließen, die PAFF decodieren können.
DGAVCDec 1.00a14 unterstützt die Verarbeitung von Transport-Streams und meckert nicht mehr über mögliche PAFF-Crashes; 1.00a15 läßt sich jetzt auch ansatzweise über Parameter steuern.
Version 1.0.0 alpha 14
* Completes transport stream support for video. You can now do Save Project on transport streams and serve the video with DGAVCDecode.
* Added Save Project and Demux Video option in the File menu.
* Added Loop Playback option in the Options menu.
* Added option to control creation of the info log in the Options menu.
* Corrected some manual problems and linked them in the Help menu.
* Removed the PAFF blow-up warning.
__Version 1.0.0 alpha 15
Alpha 15 adds a CLI interface.
Version 1.0.0 alpha 16 -- audio demuxing
This is the first cut at audio demuxing. Notes:
* The paradigm for setup of audio PIDs and demuxing is different than in DGIndex, so read the users manual! This version allows all PIDs to be processed at the same time. (The idea of moving it from the Stream menu is to allow for generalizing it to include MP4 files later.)
* AAC LOAS/LATM not yet supported.
* AV sync solution not yet decided. Currently, audio starts at the first audio frame after the start of the first decodable picture.
* CLI for audio demux not yet implemented.
* An audio stream must be listed in the PAT/PMT for demuxing to work. This limitation will be removed in a future version.
* M2TS support was fixed. E.g., the "wedding" stream now works if you dismiss the libavcodec errors, which appear harmless.
Version 1.0.0 alpha 17
1. libavcodec.dll was updated to the version from ffdshow-tryouts version 1837. This fixes decoding of some streams that previously didn't work.
2. Audio demuxing was redesigned so that streams do not need to be present in the PAT/PMT to be demuxed. A Preview operation will show all detected audio streams in the Info display; they do not have to be selected for demuxing.
3. TFF/BFF reporting for field structure streams was fixed.
4. CLI support for audio demuxing was added (-a).
Version 1.0.0 alpha 18
* Fixed a problem that caused some M2TS files to be detected as elementary streams.
* Fixed a problem that caused demuxed audio files to be held locked by DGAVCIndex.
* MPEG audio is now demuxed with file extension .mp1, mp2, or mp3, depending on the layer detected (previously .mpa was always used).
http://neuron2.net/dgavcdec/dgavcdec.html
On some streams, libavcodec.dll reports an unknown NAL unit type. If you dismiss the warnings things seem to go OK. I've verified that no such NALU is being passed from my code and I'm investigating the reason for this warning. For now, just dismiss these messages.
* MPEG audio is now demuxed with file extension .mp1, mp2, or mp3, depending on the layer detected (previously .mpa was always used).
mp3 gibts da auch? Wenn das offiziel ist, brauchen wir (zum ich) das NicAudio Plugin für AVIsynth mit kompletten MPEGAudio Support. Könnte da mal jemand ein Request im ENG Doom schreiben? DANKE!
1. Changed the name of the "Aspect Ratio" field in the Info display to "SAR".
2. Added a "Display Size" field to the Info display.
3. Fixed a bug in demuxing of LPCM audio from transport streams.
Fixes audio detection and demuxing and consequent video decoding errors for some streams.
Der MacGuyver bastelt wieder...
1. Fixed a bug that caused DGAVCIndex to crash when doing Save Project on a stream that contains a DTS audio track, and that track is not selected for demuxing.
2. Fixed a bug that caused DGAVCIndex to crash if more than 256 PPS's are encountered during the initial parsing following the opening of a stream.
