Notice to readers: These filters
require some knowledge of audiovideo matters and some of them are thought to be
used inside GraphEdit. GraphEdit is a freeware Microsoft application
distributed with the DirectX
SDK. If you don't want to download the whole DirectX SDK you might find
GraphEdit alone in many places like at the
GraphEdit is an extremely
powerful application. It will suffice to say that using Graphedit with the free
demo Elecard Mpeg2
decoder filters, the freeware OggDS
filters, the freeware ad-supported DivX5
encoder, the freeware
Multiple Mpeg2 Source, and the filters down here in this page, it is
possible to rip a DVD in ONE step with PERFECT audio/video sync, with as many
audio languages as you want and with audio up to 6 channels (5.1) with
downmixing only at play time. With one additional step using SubRip (can be
found at Doom9.org downloads)
and the freeware subtitler filters
you can even add subtitles.
All this is not optimal if you plan to burn
the resulting file on CDs, because the filesize will not be known in advance
with this technique (in facts you have to use the DivX encoder in 1 step
quality based mode). However if you plan to hold the movie on your HD there
are no problems. Use DVD Decrypter (Doom9.org downloads) to extract
the VOB files to your HD before transcoding.
Beware: in some countries
DVD ripping is forbidden even if you own the DVD you are
Configurator by Trombettworks
In the past, before the DirectShow
revolution, the codecs were in the VFW (video for windows) standard. And many
still are: the MP3 codec by Fraunhofer which you can find on your Windows, the
Huffyuv and many
other video and audio codecs are still in video for windows standard.
try to load those codecs in GraphEdit you will face one SOMEWHAT BIG problem:
they cannot be configured. If you right click on them and select "Filter
Properties" you will find absolutely nothing. You can't choose bitrate for MP3,
you can't choose any video compression setting, deinterlace...
Here comes the Filter Configurator filter: load it in the graph
and view its properties. From there you can configure any VFW video codec or
ACM audio codec you have in the graph: use the buttons on the right side to
configure a video codec; while for the audio codecs you have to select an
output pin from the list and then choose the compression format from the list
Attention: audio codecs usually require that the input is
connected to allow you choose the compression. Video codecs on the contrary
should not have their input connected when you configure the compression
or they might crash and blow up the whole GraphEdit.

If you have a multichannel ( > 2 channels )
source of audio you can downmix it to 1,2 or any channel config as you wish
with this filter. So you can hear multichannel sounds even if you have two
speakers only. This filters works in GraphEdit as well as in Windows Media
Player and other players.
Special thanks to S_O in the everwicked.com forum
for helping me with the downmix algorithm.

When selected, the Channel Downmixer will get an higher
priority than your directsound device, so it will be loaded as soon as
possible, that is before the audio renderer. This allows you to have the filter
automatically loaded also in those cases in which the DirectSound device would
already accept the sound format (e.g. a stereo 16 bit source, or a multichannel
source when you have a multichannel soundcard). But when the option is selected
you cannot have more than one instance of the filter simultaneously present
(sorry: I had to do that or it wouldn't work); so you might want to remove that
when building graphs by hand in GraphEdit.
Attention: The filter
saves its settings at every use so that the next time you will load it it will
remember its settings. This is generally good but if you set it by mistake in a
way that it's not usable anymore, the Windows Media Player will not load it
anymore, and thus you will not even be able to restore its original settings.
In such a situation you can restore its original settings by loading it
manually into GraphEdit, or by registering the filter again: it is built in
such a way that when you register it it restores its default

sources for compiling Channel Downmixer version 2.00 Beta3 here. (Note: you
need to change the ProjectSettings -> C++ -> Preprocessor ->
AdditionalIncludeDirectories to reflect the location of your DirectX SDK
installation). AGREEMENT: You can download the sources and make modifications
to this filter for your personal use freely. If you publish your modified
version I ask you to: 1) Leave my name and a link to this website, written
somewhere in the filter interface. 2) Inform me via email that you are

||- Up to Beta2 a Mono input was
considered to have the FrontLeft channel only and so when upmixed to stereo it
resulted completely panned to the left. Now a Mono input is considered to have
the FrontCenter only, so when you upmix to stereo or upper speaker
configuration the sound will result to be centered.
||- The custom downmix matrix thing
wasn't working in Beta1. Fixed.
- Added more detailed info into the bundled
custom matrix files.
- Added the .bat files to register and unregister the
filter (I had forgot them in 2.00 Beta1)
||- Added input and output
- Added pre-mix input gains and post-mix output gains with channel
granularity (so that you can raise the volume for the speech [FrontCenter]
input channel at play time and the like).
- Extended support up to 17.1
speaker configurations for both input and output waves.
- Allowed loading of
custom mix matrixes from plain text files.
- Abandoned the Quasi-Dolby
Surround Pro Logic downmix for the internal downmixing routine and relegated it
to a custom downmix matrix file bundled with the filter. With the new internal
downmix algorithm (works up to 17.1 speaker configs) a better left/right
separation is achieved.
||Added an option for force-loading
the filter even when your directsound device would already accept the sound
Fixed a bug which could cause crash in case of output bits >

Stream Shifter by
In case you have a crappy audiovideo clip in which
audio is not in sync with video, you can use this filter on one of the two
streams to shift it and re-sync things. It seems it works better if applied to
video streams than audio streams. This filter works by just changing the
playback times of the data passing through. The renderers or muxes downstream
handle the re-aligning of the data.
Notice: The AVI Mux filter saves the
data as it arrives. The Stream Shifter will work if you put it upstream
of an AVI Mux but the audio and video multiplexed streams will not be
correctly aligned on disk. If the AVI you are creating is a high-bitrate one
and you are shifting by a big amount you might notice HD head whirring when you
play it back and this can decrease the playback performances. I think Ogg files
work better than AVI ones in respect to this.

Null In Place by Microsoft
filter is given as source code sample in the DirectX SDK. I have compiled it
and put here for commodity.
This filter performs no transform at all,
but allows you to select a specific media format in the connection between two
filters. If you see that two connected filters in the graph are not talking
using the media format you want, just put this filter in the middle and use it
to force the format.
