Parameters

buffer	bitstream buffer, must be AV_INPUT_BUFFER_PADDING_SIZE bytes larger than the actual read bits because some optimized bitstream readers read 32 or 64 bit at once and could read over the end
bit_size	the size of the buffer in bits

Returns: 0 on success, AVERROR_INVALIDDATA if the buffer_size would overflow.
