decode an uncompressed avi using ffdshow and directshow function in avs

[fenomeno83]

excuse me..
I want use ffdshow to decoding an uncompressed avi file.
I created a script avs with directshow but ffdshow decoding doesn't work!
with mpeg1-2 files it's ok, but with uncompressed avi not!
in ffdshow options I choosed "all suported" for raw..
also per mpeg1-2 I choosed libvacodec as decoder....but for uncompressed avi?
How can I decode using ffdshow(I want apply its filter)?
thanks

What type of uncompressed AVI is it?

[fenomeno83]

I uncompressed it with virtual dub choosing avi uncompressed rgb/ycbcr

It's easier to apply the ffdshow filtering in VirtualDub I suppose.

If you have the ffdshow VFW component installed go to compression>ffdshow>Input>enable image processing.

also if I set ffdshow in virtualdub and set filters, doesn't work..I set uncompressed as encoder in ffdshow inside virtualdub and set various filters in decoder, BUT DECODER DOESN'T WORK AND FILTERS AREN'T APPLIED

I explain my problem: I have some 3gp files on which I want increase quality..
I tried some filters in real time with ffdshow and I got good results..
But now I want apply this filter!

my idea was use an avs with directshow to apply this filter, and pass this avs tu automkv to use h264 as format of final file (for don't use uncompressed file)..
directshow doesn't work with 3gp..for this I used ffmpegsource that recognize 3gp but don't use ffdshow..
An indea is create an uncompressed avi file using ffmpegsource and that use directshow in this uncompressed avi to use ffdshow, compriming also in h264 with automkv..
but ffdshow don't decode uncompressed avi files...I tried to change fourcc of uncompressed avi in RGB3, but also if in this case ffdshow can decode it, image became unreadable after that I changed fourCC

how can I solve?

Please read my post more carefully. Don't set the filters in the decoder tab when compressing. Of course that doesn't work.

doesn't work, also if a set image processing and set ffdshow filter, this doesn't applied in encode processing with virtuadub

but I found solution:
open 3gp using ffmpegsource and save using uncompressed of ffdshow (uncompressed of virtualdub has problem)
change fourcc of this uncompressed in RGB3
now use automkv-h264 encode loading an avs with directshow function

perfect

This does work. I am using it fairly often.

[fenomeno83]

I don't know...also If I use this option, ffdshow doesn't work
this is a difference: I don't find in ffdshow configuration of image processing,voice "supported codecs" to set RAW..maybe is this the problem?

ps: i tried this importing avs with ffmpegsource("...3gp")
