Dyami Caliri	50833c9f7b	Fix buffer_size argument to init_put_bits() in multiple encoders. Several encoders were multiplying the buffer size by 8, in order to get a bit size. However, the buffer_size argument is for the byte size of the buffer. We had experienced crashes encoding prores (Anatoliy) at size 4096x4096.	10 years ago
