I am not saying Photoshop is wrong, but I read it as "RGB" "8bit", so I don't know where to find the additional information. (It may be a Photoshop-specific tag and that is what gimp's warnings indicate.) >> Since you used "image2pipe" in the subject: >> There is no tiff parser, so you cannot generally use >> input format image2pipe with tiff images, but this is >> unrelated to the samples. >> (Patch welcome.) > > I'm not sure to understand.

The idea of image2pipe is usually to feed a series of images to ffmpeg, a parser is needed to find the beginning of the next image.
