The German Wikipedia is a good start, it contains all necessary
information to understand this issue:

Yes, in general, commentaries are not necessary to decode
multimedia streams, broken parts of files can cause decoding

I meant: Which brand and model is the camera?
Recognizing the encoder would make fixing your issue easier.
