Hi Chris,
Thanks for your answer.
I just replace my pix_image object with pix_film and it works. I also send it a RGB colorspace message at loading time, this way PNGs are showing fine. Without the RGB message, JPGs are showing fine but not PNGs. Do you have any ideas why it works with JPGs and not PNGs?
Quicktime will convert YUV to RGB automagically, but not the other way around. pix_film defaults to YUV because it is the proper color-space for video and also quite a bit faster than RGB. PNG images are RGB with lossless compression, while JPEG are YUV with lossy compression applied.
