yihua resolved OPENMEETINGS-2182.
---------------------------------
Resolution: Fixed
Now I know how this happened.
First,because i use Centos7/8,the KMS must be installed in the Docker:
#docker pull kurento/kurento-media-server
then running the KMS service and must mapping the om's data directory to
centos's.
#docker run -d --name kms -p 8888:8888 --mount
type=bind,source=/opt/apache-openmeetings-5.0.0-M3/webapps/openmeetings/data, \
target=/opt/apache-openmeetings-5.0.0-M3/webapps/openmeetings/data
kurento/kurento-media-server
/////the second:
I could enter the meeting room after the above operation completed , but a
new issue appeared.
the Video/mp4 file not generated,so I went to see the log file and the
relevant media files .The log is shown below:

OK,we can know where the problem comes from.My fffmeg version is 2.8.15,It's
{color:#172b4d}encoder 'aac' is experimental but experimental codecs are not
enabled,we should add '-strict -2' if we want to use it alternatively use the
non experimental encoder 'libfdk_aac'.{color}
the command is :
