Thank you. But now i get a different error:

Number of stream maps must match numer of output streams

I don’t know what this means…

From this site i had the first version i used. The version you said its an old version. I don’t know how i have to integrate the filter.
ffmpeg -bsfs give me this information:

Thank you for your answer. I have downloaded the version 0.9 and tried the command:

ffmpeg -i abm.mkv -map 0 -vcodec copy -acodec copy -vbsf h264_changesps=level=41 abmmuss.mkv


But i get a mistake notification: Unknown bitstream filter h264_changesps=level=41

I don’t know where the mistake is. Are you able to help me?

Thank you
