Because in ff_flv_decode_picture_header there is this code line:
    s->pict_type = FF_I_TYPE + get_bits(&s->gb, 2);
However I obviously missed the following lines:
    s->dropable= s->pict_type > FF_P_TYPE;
    if (s->dropable)
        s->pict_type = FF_P_TYPE;
which wouold mean that only I and P frames exist, so
the change would be wrong.
Wonder what is going wrong then...
