2011-10-08put_bits: fix invalid shift by 32 in flush_put_bits()Mans Rullgard
If flush_put_bits() is called when the 32-bit buffer is empty, e.g. after writing a multiple of 32 bits, and invalid shift by 32 is performed. Since flush_put_bits() is called infrequently, this additional check should have negligible performance impact. Signed-off-by: Mans Rullgard <mans@mansr.com>
