ignore something being written to apache error log

Hello, In my apache error log I am getting 1000s of entries like the following, how can I fix this or at least stop it being logged to the apache error log? is there a way to ignore/exclude this? , it looks like it is related to ffmpeg which in fact is working fine so just ignoring the error would be fine. thanks

yes but ffmpeg is working just fine so just ignoring the error would be OK but how can I exclude this being logged to the apache error_log. im getting 1000s of entries per day and each is 18 lines long so the error log is massive.
