View Full Version : VfW DirectShow Wrapper - possible?

Hi,

this is a question to our coding wizards :)

Just wanted to know if it's possible to create a wrapper which acts as a VfW driver but can load files with only DirectShow drivers bound to them (just like DirectShowSource in AVISynth but without the scripting, with sound and framerate detection).

Another possibility would be a frameserver which can be selected as compressor codec. If you compress a movie using this codec it would then create a proxy AVI which then could be opened with any software (that supports AVIs - of course).


I'm asking for this because I'm working with stuff like Graphedit quite often these days (converting RealMedia files using Gabest's excellent RealMediaSplitter) and RADVideoTools and don't want to create these huge intermediate MJPEG or HuffYUV compressed files just to be able to load them into VirtualDub for further editing.

Not sure if I got it right, but sounds like you are looking for:

VFAPI, or something similiar,..

DirectShowSource has been updated with seeking and sound support in the latest CVS binary (see my signature).

ffvfw can be used to create fake AVI's from AviSynth scripts. (Use search)

Yeah - I've already taken notice of this - good job :)

I tried it with a RealMedia Clip via Gabest's RealMediaSplitter. Works so far but I don't get A/V synchronized (I think this may be a VFR problem).

Is there a way to let AviSynth "guess" the right framerate?
