// frame N it needs frame decompressed frame N-1 available to calculate
// it, unless we are at a keyframe. So with keyframed codecs, you can't
// get away with applying the transform to change the frames in place,
// because you'll mess up the next frames decompression. The runtime
// MPEG decoder does not have keyframes in the same way so it can be
// done in place. We know if a sample is key frame as we transform
