# note: Mode data for 15 macroblocks in a frame whose dimensions call for 16. # expect: ok # roundtrip: no # exercises: The missing macroblock is decoded out of partition 0's padding # without the reader ever running out, so the frame is accepted and the # last macroblock decodes to whatever the padding happens to say. Nothing # checks that the mode data is as long as the frame claims to be. # Reading the file back gives 16 macroblocks, so it is the one case # here that cannot be disassembled and reassembled unchanged. width 64 height 64 yac_qi 30 mb_no_skip_coeff 1 prob_skip_false 255 macroblock count 15 mb_skip_coeff 1 intra_y_mode DC_PRED intra_chroma_mode DC_PRED macroblock_count 15
