Hi everyone,
I'm going to build *native directshow*, but cannot obtain.
Currently, I'm using visual 2005 to build .dll file successfully, but I
cannot use this to run on libjitsi.

Anyone know how to build *native directshow*, plz help me deal with this
problem.

Thank in advance!

Please be more specific about why you cannot use the built .dll with libjitsi.

Anyone know how to build native directshow, plz help me deal with this
problem.

We use MinGW to build directshow using "ant directshow" executed in
the root directory of the libjitsi project.

Hi,
Actually, I can run .dll with libjitsi properly.
Now I need to edit the native code of directshow to get black&white video,
I mean I apply transform to raw data captured from camera before send it
though to peer.
Could I can get raw video bytes before send it to make transformation at
JAVA code?

If we were to implement it, we'd likely go at it in a fashion similar
to the FMJ Effect implementation
org.jitsi.impl.neomedia.codec.video.HFlip that we currently have.

How can I use HFlip?
And if I need add more filter on video, I think I should edit native code
is more efficient, right?
