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

it could be that the decoding backend does not support alpha channels. i'm pretty sure that recent versions of Gem with gmerlin do support alpha (at least i remember having spent some time for that). if you can provide a (short) video with alpha i could test.
