The ProRes encoder allocates huge worst-case buffers just to be safe; and for huge resolutions (8k in this case) these can be so big that the number of bits does no longer fit into a (signed 32-bit) int; this means that one must no longer use the parts of the PutBits API that deal with bit counters. Yet proresenc_kostya did it, namely for a check about whether we are already beyond the end. Yet this check is unnecessary nowadays, because the PutBits API comes with automatic checks (with a log message and a av_assert2() in put_bits() and an av_assert0() in flush_put_bits()), so this is unnecessary. So simply remove the check. Fixes ticket #9173. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
