 > How did you create the input file?

 Unfortunately, I did not create the video. It is automatically transcoded
 via a messenger application. (I do not exactly know how they transcode)

 I know how to avoid this issue, (just not prepend the extra-data, if the
 extra-data has already existed on IRAP frames)

 However, I do not exactly know whether this solution is correct or not.
