Audio (AC3/DTS/MPEG/LPCM) and Video (MPEG2) plugins

opsis81 · 8th February 2005, 03:35

Download FilmShrink from
http://filmshrink.sourceforge.net/

FilmShrink is a DVD-Video backup software for Windows, which transcodes video titles into the RealMedia format (RealVideo / RealAudio 10) powered by the Helix DNA platform.
BUT!! it includes some new avisynth filters

MPEG-2 Video Decoder Plugin for AviSynth 2.5 (m2input.dll)
AC-3 Audio Decoder Plugin for AviSynth 2.5 (ac3input.dll)
DTS Audio Decoder Plugin for AviSynth 2.5 (dtsinput.dll)
MPEG Audio Decoder Plugin for AviSynth 2.5 (mpainput.dll)
LPCM Audio Decoder Plugin for AviSynth 2.5 (lpcminput.dll)

Sounds very promising! The site is a bit slow/down

I changed the title a bit

edit: I can't get AC3Source or DTSSource to work. Did someone have any luck?

opsis81 · 9th February 2005, 00:25

You should change the title

.
FilmShrink seems to indexes the vob first.Something like d2a cration

These filters seem to be the m2tools pack.The source code of m2tools can be downloaded from http://filmshrink.sourceforge.net/dl.html.
Have a look at it.

What input does the m2input.dll plugin supports?

Wilbert · 9th February 2005, 21:36

I'm not sure. If you look at mpeg2dec.c it says * Jun 20, 2004: Derived from "DGIndex 1.0.12" by Attila Afra. Perhaps "it's" just dgdecode 1.0.12. I do know it should be called with mpeg2source(blabla).

I will mail him about this.

Sirber · 9th February 2005, 21:50

ok, so it takes D2V files. Thanks for the info

a_afra · 9th February 2005, 22:41

Hi,

My name is Attila Afra, and I'm the developer of FilmShrink. I've noticed that a few people are interested in the new AviSynth plugins used by FilmShrink. These plugins are part of m2tools, which can be downloaded (full source code) from FilmShrink's homepage. m2input is a slightly modified version of DGDecode (it accepts M2I files, which are VERY similar to D2V files, but there are a few differences, so it's NOT compatible with those) and ac3input/dtsinput/lpcminput/mpainput were written by me using different decoder libraries (liba52, libdts/libdca, MAD). The cause of your problems is that the video/audio plugins can ONLY accept files generated by m2index, the main indexer library, which is based on DGIndex. m2index first creates a "full" video/audio/subpic index, from which you can later rebuild (using the m2rebuild function) the index of a single PGC/angle, usable by the plugins. I will soon (this weekend

) write a detailed description on how to use this package, and I will release a sample command-line tool (with source) which uses m2index. Until then I recommand experimenting with the files located in the hidden ".fskj" directory of the jobs created by FilmShrink.

And don't forget to check out "m2index.h" and "m2index_info.h" from the m2tools source package! I'm awaiting all your questions and suggestions...

Does the latter mean we can open dts/ac3/etc in AviSynth by using the index file created with m2index (and the command-line tool)?

a_afra · 10th February 2005, 19:50

Yes, you can! In fact, there will be two tiny tools: one (simply m2index) for creating the main (full) index, and the other (m2rebuild) for rebuilding it to get the index of the desired PGC/angle. Both will use "m2index.dll". Note that the AviSynth plugins included in m2tools can only accept the rebuilt index, which is NOT compatible with any other plugins! By using m2rebuild, you can immediately decode any PGC/angle without extracting it from the DVD using a tool like vstrip, DVD Decrypter or IfoEdit. Also you don't have to demux the audio streams: the only things you need are the index files. m2tools supports multi-angle and seamless branching DVDs too, so it's quite powerful (I've tested it with "The Matrix" and it works fine)!

Wilbert · 1st March 2005, 22:18

Any news?

a_afra · 3rd March 2005, 20:09

m2DecPak 1.1.1 SDK is available for download! I had to rename m2tools because I've noticed that there is already an m2_tools. Sorry for this huge delay, but I have very little spare time and I had to concentrate on the development of FilmShrink's main module. You can download this package from FilmShrink's download page. The SDK contains the include files, the compiled libraries, examples (the sample command-line tools) and a detailed description about the usage of this package outside FilmShrink. You should also download the source code and the latest version of FilmShrink (0.2.8). Looking forward to feedback...

Backwoods · 4th March 2005, 03:05

I just tried out your AC3 filter, it's perfect. Only problem is the CMD stuff. I used Filmshrink instead and copied the temp files it made and used those. Otherwise I couldn't get it to work.

E-Male · 4th March 2005, 05:27

does this only work on DVDs, or can i also create indexes for already demuxed streams?

Backwoods · 4th March 2005, 05:42

I'm pretty sure it's only VOBs and IFOs.

a_afra · 4th March 2005, 09:31

Yes, it can index only DVDs (demuxed ones aren't accepted)! Also make sure to copy "m2index.dll" into the directory from where you launch the command-line tools! It should work without any problems.

Example usage:
m2index.exe "VTS_02_1.VOB|VTS_02_2.VOB|VTS_02_3.VOB" main true true
m2rebuild.exe main VTS_02_0.IFO movie 1 0 true true true

E-Male · 4th March 2005, 10:44

i see, but could it be modified to work with demuxed files?

a_afra · 4th March 2005, 19:27

No. It is possible to index the demuxed video stream with m2Index but you won't be able to use m2Rebuild and decode the video using m2Video. But you can decode a demuxed audio track if you manually create a .VFM file. It should look like this (without < >):

VirtualFileMap10
1
<full path of the demuxed audio file>

0 <length of the file in hex>

.

Pass this file to the proper decoder filter.

E-Male · 4th March 2005, 19:46

thx, i'll look into that

Nic · 30th March 2005, 18:52

Is anyone interested in these filters as standalones for loading raw audio files such as AC3, DTS, etc?

It's very easy to convert them, (I'm thinking someone else has
already done it, but I can't find it with a search).

(I could just join them all into one DLL pretty easily)

Here's an AC3 one for example:
