[PD] problem in compiling puredata_opencv

[ydegoyon at gmail.com]

ola,

yeh it's quite clear...

the yuv images that comes from your cam
must be converted to rgba with pix_rgba
before being passed to opencv
that only works with rgb and grey internally..

[pix_video]
|
[pix_rgba]
|
[pix_opencv_...]

suerte,
sevy
