thnx,
I thought the pix_video_ds, later pix_videoDS has now become the standard pix_video and was integrated into GEM??? I am starting to mix things up, better I have a short break and go through docs and mailing list again, to many OSs and versions...
cu, marius.

hi, hmm, seems I run into a driver problem. I got the current CVS-version compiled again, alpha-blending is now working, but the video is vertically flipped... (linux) on windows the pix_video crashes pd. are there more versions of the pix_video? marius.

pix_rgba will add the alpha channel if it's not already present. I think
by now
all of the capture objects in CVS should deliver a pixmap with 32bit RGBA
on all
platforms.
The [alpha] object enables alpha blending of GL objects, and does not
affect
pix_ data.
Apart from the misplaced alpha object, the chain below should end up with
a
buffer that contains an alpha channel. However, pix_alpha seems to be set
up
for some keying functions so you probably have to supply the threshold
values to
avoid completely opaque images.
You don't say what the purpose of the patch is so I can't really advise
much
further. There are other objects that will directly do blending (pix_mix)
and
keying (pix_chroma_key) without the alpha channel. Perhaps try one of
those if
they fit the bill.

Quoting marius schebella marius.schebella@chello.at:
hi,
is it possible to convert the liveinput (pix_video) to some format with alpha channel? i tried [pix_video] [alpha] [pix_rgba] [pix_alpha] ... doesnot seem to work.
marius.
