Take JPEG, the C. elegans of compression codecs, as an illustrative example. Encoding an image requires a 2D frequency transform (partially parallelizable, processing rows then columns), DC value prediction (fully serial), quantization to discard perceptually irrelevant information (fully parallel), and finally Huffman coding (extremely serial). The mix of parallel and serial steps turns out to be the central challenge for GPU codec acceleration.
