As the second argument for init_get_bits (buf) can be crafted, a return value check for this function call is necessary.
'buf' is  part of  'AVPacket pkt'.
replace init_get_bits with init_get_bits8.

The existing error concealment makes no sense for the image formats, they
use transformed source images which is different from keyframe + MC+difference
for which the error concealment is designed.
Of course feel free to re-enable this if you have a case where it works and
improves vissual results
