Known Issues - Red5 Pro Server


  • For Safari < v12, iOS SDK broadcast cannot be viewed with WebRTC in Mac or iOS Safari.
  • With the release of Microsoft Edge Chromium, we have dropped support for older versions of Edge
  • IMPORTANT: Because of different libcrypto library versions supported between CentOS and Ubuntu, with releases > 5.2.0, if you are using CentOS it is necessary to modify {red5pro}/conf/webrtc-plugin.properties, and change openssl.enabled=true to openssl.enabled=false.
  • Some issues with some versions of Safari WebRTC <==> Firefox WebRTC
  • HLS playback over clustered server may freeze after 20-30 minutes (refreshing page will resume playback)
  • If Using the Orientation Post Processor, note that the Android SDK recordings take approximately 3 times the duration of the file to convert to MP4; modify the cloudstorage-plugin.properties file, setting the max.transcode.minutes= value to allow for this timing
  • IMPORTANT UPDATE FOR RED5PRO SERVICE: if updating from a previous release, the line -cp ${RED5_HOME}/commons-daemon-1.0.15.jar:${RED5_HOME}/red5-service.jar:${RED5_HOME}/conf \ must be modified to -cp ${RED5_HOME}/commons-daemon-1.1.0.jar:${RED5_HOME}/red5-service.jar:${RED5_HOME}/conf \ as of release 5.7.0. See here for full service file syntax.
  • If you are upgrading your server/webapp from a version older than 5.4.0, please see these details on including a websocket filter to your webapp.
  • There are threading issues on Ubuntu 18 which may lead to OOM errors at more than 1,400 connections.
