How can I install a directshow filter ?

[ADLANCAS]

Hi,
I'd like to test some directshow filters when I make a capture using IUvcr program. I have, for example, a filter Deinterlace.ax that comes from DScaler project, but I don't know how can I install such file.

Thanks,

Alexandre

Just unzip the .ax file, most users put them in the windows\system32 directory, then register the file from commandline: regsvr32 deinterlace.ax

Great!

By the way, do you know if I can use filters .dll (as used in Dscaler) as a directshow in my aplication IUvcr? Could I use the same command ?

Thanks again!

If they are directshow filters, yes, the command is the same, but be sure, not all .dll's are DShow filters.

Please,

I´ve just installed two directshow filters:
- Deinterlace.ax (from Dscaler)
- AlparyDenoise.ax (from Alpary)
and installed also lastest version from Dscaler (4.1.8).

Since then, I had problems playing a video captured in YUY2 with Huffyuv in Windows media player, PowerDVD and with BSplayer. I don't know how to explain how is the played in the screen, but it seems that the video is divided in 3 parts and mixed up.

Players work(play) perfectly with another codecs like a PicVideo Mjpeg or DivX 5.02.

So, I installed the last version from Huffyuv (0.2.2) and continue to have problems. When I open this videos in Vdub it works also perfecty.
After that I also installed DirectX 9.0b.

My OS is XP Pro.
Some ideas to fix this? or How can I unnistall a directshow filter ?

Thanks,

Alexandre

Is here a correct place to put this subject ?

Uninstalling is just as easy as installing:
regsvr32 /u deinterlace.ax

Finally I found the reason!
I was using a old version from ffdshow!
With the newest version alpha, it works.

Thanks anyway,

Alexandre
