how to check opus encode frame has FEC

I want to know if an opus encode frame has FEC information or not, I checked RFC6716 and 7587, but can't find the answer, anyone can help? Really appreciate your help!

Are you looking for a tool that will just tell you this, or do you want to examine the frames by hand?  Isn't FEC encoded in an LBRR frame?

Lithopsian,  thanks a lot for your answer! I want to check the frames by hand, now I have the encoded frames, and want to know if there is FEC data in these frames, do you have any idea? Thanks again!

I got it, just to check if there are LBRR frames in the package, right? Really appreciate your help!

I can't guarantee, but yes so far as I know the LBRR frames are the only way that forward error correction is encoded.
