I am still not having any luck with this. I have added '-strict -2" to both --extra-cflags and --extra-ldflags and have successfully compiled, but when I try to run my app, the avcodec_open2 function fails and outputs the following to the log: 

[aac @ 0x10700cc00] The encoder 'aac' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.

Where does this '-strict -2' need to be added to enable the proper codecs and get past this error?
