Check How Many MediaCodec Instance Your Device Support

Lol, I have to admit you are right.
IMO, I just don't want to use magic numbers in the project.
Cause that might cause some accidents if other developers don't know what the number is for.
I am not saying your code is not ok or bad (I basically love that cause it's more clear), just try to figure out if there is a better way we can do :)

But anyway, you are the first one (and probably the only one) who is interested in this example and are willing to discuss it.
Really appreciate that. Thanks :)
