Hello to all,
I discovered a bug of bicubic filter, introduced with version 1.3: when I resize a video source from higher resolution to lower, it crash! Sure this filter is created for the *opposite* task :D but I really need this (I have many video a 720x576 but my TV have a VGA-in limited at 640x480 and I want rescaling with the best quality, my video card hardware rescaling is simple *orribile*...) , and the 1.2 do not have this problem.
Anyone know the email of developer, to report this bug ?
And anyone can email me an older versione of bicubic fileter ? I accidentally deleted it and and anywhere i the web I found only the newest...
thanks

Sorry, haven't got an older version and couldn't find one either, but you could try this instead:
Download Avisynth, install it and write an .avs file that looks like this:

DirectShowSource("Whatever.avi")
BicubicResize(width,height)

Then open the .avs file with media player and you got your resized video.

Thanks, but it is the first time for me that I use Avisynth...it works, but without audio!
How I must do to ear audio with avs file, from an DivX+MP3 avi file ?

your avi has to contain wave audio in order to work with avisynth. or you can insert audio from an extra wav file following the sample:

video = DirectShowSource("YourVideo.avi")
audio = WAVSource("YourWave.wav")
AudioDub(video, audio)
BilinearResize(width,heighth)

ps: bilinear resize is faster and is almost the same quality as bicubic.

Thanks to all

Anyway, bilinar yes is faster but because I need use it for playing my divx with mp3 audio, I cannot use bilinear with avisynt (no audio from MP3) and so I need a directshow filter...
When someone will make a fast bilinear directshow filter, I will very happy because sometime (high bitrate divx) my CPU is not enough powerful for playing with real-time software bicubic filtering....

there is in fact a faster way of resizing: simpleresize plugin for avisynth. it's in the download section at doom9.

BTW: have you recieved the directshowfilter yet? i thought vinetu sent you an e-mail?

uhmm, do not seems to much faster than bilinear included with avisynth. Anyway if avisynt cannot play mp3 audio, it is useless for me

yes, thanks to to vinetu

when i try to use this bicubic directshow filter, it just makes the image all garbled and i can't make out anything. has anyone else had this problem?

Funny, I had the Bicubic resizer crashing all the time, trying to reduce a 720x480 DVD to VCD size. I didn't even think to try it the other way, to expand a smaller image.

The
Moonlight Scalar (http://moonlight.co.il/products/ir.shtml) has been an excellent tool for me, reduces, crops images, and also handles different colorspace formats.

Very interesting, but it is usable for AVI playing with Media Player ? How ? Afer registering filter, it is not loaded automatically by Media Player like others directshow filters...

Thanks Very Much!
