Format profile : LC@L4

The logs shared says that the profile level is 4. The latest gitHub version does not have support for Level 4 files. We are currently working on adding support for this profile. The old version might also be able to decode it only with some workaround.

Thank you! I completely forgot I performed the workaround in issue #1 in the old code. I tried applying that to the current code and still got the same behavior (it's on a different line but the neighboring logic seems to be the same). I believe some other addition to make the program conform to the standard fixes the "bug" that makes the workaround possible. I will wait for the support for Level 4 and close the issue then if that's OK with you.

@sclsj Can You once try with the latest version of the decoder?
