Hi,<br>
<br>
No, I am not using pix_alpha, because that's not what I need.<br>
pix_alpha changes the value of the alpha channel, so that pixels within a given range of colors _become_ transparent.<br>
<br>
In my case the video file itsalf already has an alpha channel and I want the pixels that are transparent to remain transparent.<br>

Hi Matteo,<br>
are you using pix_alpha?<br>
you could try this patch here, which works on my system, with a video<br>
encoded as "JPEG still images" (properties window video tab in gnome)<br>
ubuntu 10.10, pd 0.42-5 extended.<br>

Hi,<br>
<br>
I'm trying this:<br>
<br>
[pix_film]<br>
|<br>
[pix_texture]<br>
|<br>
[alpha]<br>
|<br>
[rectangle]<br>
<br>
I'm using some videos that have an alpha channel and I had tried<br>
them previously in Windows and Mac and they were rendered correctly<br>
with their transparent background.<br>
<br>
Now I am trying the same in Linux and the videos are opaque, as if<br>
they didn't have an alpha channel or as if they had an opaque black<br>
background.<br>
<br>
I've already tried sending "colorspace RGBA" to pix_film, but<br>
nothing changes.<br>
<br>
I'm almost sure the videos were encoded with the Apple Animation+<br>
encoder but if i right-click them in Ubuntu and select "properties"<br>
it says "run-length encoder". What is sure is that i tested them in<br>
Windows and Linux and used to work.<br>
<br>
Any idea?<br>
<br>
thanks<br>
m.<br>
<br>
