How to make DivX Connected use LAV Filters?

[LigH]

Long, long time ago, there was this decoder box called "DivX Connected" which is able to decode realtime-transcoded videos transmitted via LAN or WLAN. Not quite the worst product ever, but not very common either. As a beta tester in those times, I still have one of them.

I remember how much hassle it caused to make the server application support more formats by implementing Haali and ffdshow as DirectShow splitters and decoders. It didn't work easily in all cases.

With LAV filters today, I believe chances are better, therefore I wonder if anyone still has some documentation how it worked; Kamiwa's blog disappeared, and so did most of DivX Labs' topics covering this product.

As far as I remember, the key to success was registering the CLSID of a DirectShow filter to either a container format or a content format. One of the quirks with Haali was that it offered more than one splitter filter... What do LAV Filters provide, are there several CLSIDs or just one each for the splitter and the decoder?

LAV Splitter also comes in two variants like Haali Splitter does. One filter that combines both a source filter and a splitter ("LAV Splitter Source" / {B98D13E7-55DB-4385-A33D-09FD1BA26338}) and one that is just a splitter ("LAV Splitter" / {171252A0-8820-4AFE-9DF8-5C92B2D66B04}). For reference, the "AR" version of Haali's filter is the splitter, the other is a source filter.

Look at this registry key for setting things as preferred:
HKEY_CLASSES_ROOT\Media Type

This seems to relate to <readerGuid> for a source filter and <demuxerGuid> for a splitter filter in the file DCDShowPlaybackPlugin.config; I will try to make it work.

Do you also have a GUID for the decoder (which used to be ffdshow in earlier attempts)?

LAV Video is {EE30215D-164F-4A92-A4EB-9D4C13390F9F}

You can easily find the GUID (and other details) of any filter with GSN.
