Hi Luca,
Thanks for this advice.
Meanwhile to was able to run this task with the libav API functions.
But I also will try version 9.
Best regards

Looks like there is a bug that makes it assume the h264 bitstream is not formatted as he would expect, yet, since it has extradata it fails to use the current filter.

Please check with libav9, it might had been fixed already.
