Comment (by alexpigment):

 jkqxz: I didn't realize it was looking for that sort of string. Thank you
 very much for point this out. Perhaps it should recognize 4.1 as well so
 that that people could use the same syntax from encoder to encoder.

 DeHackEd: No, that was my understanding as well. I realize that it was
 picking 4.0 in my case because it's not hitting a bitrate that would cause
 it to move into 4.1. I was just saying that ideally there would be bitrate
 limits tied to whatever level you choose, which unfortunately I hadn't
 been able to test until jkqxz clued me into the level_idc value thing. I
 can now confirm, however, that the bitrate limits don't seem to be in
 effect. The same is true for libx264 of course.
