framesPerSecond
Hello
When recording video with openmeetings (the icon in the upper right corner) the quality of the recording is poor, with the video in the folder webapp/openmeetings/streams/hibernate/.
Picture twitches seems that the small value of frames per second.
Parameter increased framesPerSecond not help
