Subject: Re: single pass .rvf video conversion with DirectShow filter
From: Lyndon Drescher (lyndondr_at_newnorth.net)
I tried it and the audio is there but there is some beeping sounds of
various tones. The video conversion was a snap. My video source came from
my Tivo and was an mpeg file. Tivo's audio uses a 32khz sample rate I'm not
sure if that's the problem. I tried to use the lame encoder but it didn't
want to fit in place. Any ideas of what I should try?

Subject: single pass .rvf video conversion with DirectShow filter
it's implementation friday again!
Since a while, I have been working on a way to convert videos to .rvf
directly in one step, quick and without any preprocessing/scaling, etc. It
DirectShow renderer, consuming YUV video and MPEG audio which the rest of
infrastructure (the regular demux/decoders for media files) can provide. My
component does the scaling, halftoning and the multiplexing. No HD spilled
big temporary files, and more variety of media to use as a source.
This code is now moving for the first time, you can try my alpha version in
a sneak preview:
(fresh off the bench, no guarantee that it'll work for you, don't complain
You will find a readme file there explaining the rest, how to use it with
the "GraphEdit" test application from the MS DirectX9 SDK. I have included
there, so you don't have to download the whole SDK from Microsoft. ;-)
I'd welcome a volunteer who makes a conversion application around this. It's
not difficult, some COM interfaces can tie such a graph together. John?
