Media Encoder -- Audio -- Advanced Settings -- Precedence -- What is the difference between the two options presented here and how does it effect the final file?

Question

I see no literature in any of the manuals that explains this option -- what is it exactly and how does it work?

Um...have you compared when specifying v = 0x0FFFF, as an arbitrary example?
Edit All right I'll be a little more specific. How the heck would your Test1 method know if it's only being passed int values <= 255?
Edited by: endasil on Nov 6, 2007 8:48 PMI see, well, why would it care? all it does is take int and store it into a byte. what else could it do with an int and byte array? Also, if you wanted to check for values <= 255 one could simply add asm code to do that, after all, Test2.test2() has a signature of ([BI) that is (byte[] ba, int v). So, if the method wants to fool around with v* it can iload_1* and do any comparison tests, ifeq* etc..., and latter stuff it into byte array using bastore* without the unnecessary i2b* call.
I just don't see the use of the i2b* instruction if bastore* could careless. Will this cause the stack to become unlined and cause trouble program down-the-line in execution? I am thinking that I loaded an int*, +4bytes+, but only consumed 1byte. But now that I think about it, iload_1 loads an int* onto local heap so it should get cleaned up when the program exits. So, as long as I made bastore* the last instruction in the program I shouldn't have a problem. Or maybe this doesn't matter either?
*Also, since ba is an byte[] why would I want to check it for anything other than a byte value? if I wanted to get an int I would have created an int[]*
My point is that as long as one wants to stuff an int into a byte array the i2b instruction is overkill, albeit not much, and I just do see the usefulness of it.
This is for when I do something like, byte_array[i] = '-', and the compilers say loss of information and I cast '-' to (byte)'-', meaning I don't care if I loss any information. but it called i2b anyways byte_array[i] = '-' yields the same result.
I just didn't understand what was behind this.
Does that answer that question or am I missing anything?
