Summary:
The behaviour of the decoder (and image2pipe but not image2) has changed
in ffmpeg master for certain input images, meaning with the same input you
get different output now. Especially that mean, that before the supplied
jpeg decoded with no error and output a 64 KB image. After decoder errors
out with invalid data and cannot reproduce the same image as with the
latest stable version.
If this is wanted and such jpeg images shall produce two output images in
the future _and_ need to be split up prior to be sent to the decoder by
hand (as image2pipe fails to properly split them), then please leave a
comment.
