    avcodec/diracdec: Fix qfactor/offset tables · 5fbd97fc
    Michael Niedermayer authored
    It seems the previous tables where calculated with 32bit integers ignoring
    overflows.
    Also check for the max qindex, the value is choosen so that the qfactor/offset
    fit in int32.
    
    Fixes: 070b7914fd5dfe8f93248bea71363410/asan_static-oob_c8d034_2764_258e20f4a3c79158aecddb61a833d756.drc
    Fixes out of array reads
