Capture into AviSynth
Is there a way for me to capture directly into avisynth so I can manipulate the video on-the-fly. Perhaps a filter like capturesource() or something that would work like that. I would like to use AviSynth becaues it if verry versetile, however if there is no way of doing this with AviSynth directly how would I go about doing this?

As far as I know this is not possible. Processing a capture on the fly is very resource intensive. I've never been able to do it with good results. Capturing then filtering through AVI-Synth is still yields the best quality as far as I know.

If this would be possible, we are able to build our own Stand-alone Standard-converters!
capture -> avisynth conversion -> mediaplayer playback -> TV-Out This would be great! A PC as high configurable black-box-converter!

Sorry for necroposting. Maybe somebody find it useful:
HV30 (HDV camcorder) via FireWire - Graphedit - PowerDVD10 demuxer (directshow filter) - ffdshow (with avisynth) - Render (or any other output) I can't get it work without PowerDVD10 demuxer. Maybe there is another DirectShow filter than can demux mpeg-2 ts (hdv)? |

You cannot use a capture source as input for Avisynth. Avisynth requires the number of frames in the input to be known at the time the script is created (and it does not provide any means to prevent random access). A capture device naturally does not provide the number of frames, so there is no point in setting up elaborate DS filter chains trying to get it to work.

I've been using the following graph:
capture source -> ffdshow raw video filter (with built-in real-time avisynth scripting) -> compress (x264vfw) -> whatever output you have available as a directshow filter (file output, rtsp stream) |
