Global side data as exported by a decoder may no longer apply if a filter in the chain altered the frames in some form, like changing color, dimensions, or channel layout information. After this change, any such changes in side data will be taken into account by the encoder futher in the process. Signed-off-by: James Almer <jamrial@gmail.com>
