Capturing video and applying AviSynth filter at the same time...

[joshbm]

Is there a way to capture video real-time while applying filters in real-time? All I really need is to have the ability to see the image on my laptop while filming and applying a filter in real time.

I do not necessarily need to apply AviSynth filters in real-time, but I tried to apply some VirtualDub filters in real-time, using VirtualDub. But it doesn't work either. The only capture device in VirtualDub I have is Microsoft "WDM Image Capture (Win32)" and it won't let me capture or even preview the image.

It seems you using a wrapper for making WDM drivers available in Vdub.

a) The latest Vdub supperts WDM drivers directly
b) RGB filtering while capturing does force a mega high CPU load, so dropped frames (imho) will be obligatory
c) If you see a real goal in avs filtering during the capture process, then this is possible via ffdshow used as encoder, there you can choose from libavcodec compressors/filters up to handling avs scripting.

Thanks,

Yeah I used ffdshow. It works great! I am applying multiple plugins in realtime (while still recording).

But drop frames are of no concern for me. I only need it to preview it.

Sorry Incredible. I cannot work out how you can achieve point (c). Please, explain in details how to do it.

Thank you in advance.
