Notice For Upgrade V3 To V4

The config and settings in v3 panel will be imported to the v4 panel after the upgrade is completed. But there are a few incompatible changes between v3 and v4, please read the following changes before upgrade.

  • The default panel login username and password will be reset to admin.
  • The builtin RTMP server's application name has changed from live to stream.
  • The HLS 8888 port is no longer exists, it's using panel administration port for HLS.
  • The prefix /stream will be added to the HLS URL. For example: http://192.168.2.1:8888/1/index.m3u8 will be changed to http://192.168.2.1/stream/1/index.m3u8.
  • A new stream id will be assigned to the original stream 0, because the stream id in v4 panel is start from 1.
  • The HLS ABR settings is also changed now. You need add multiple Video/Audio Encoders and create multiple HLS outputs and add an additional HLS Master output for select the HLS outputs you created.
  • Login to the https://www.xaccel-codec.com (opens new window), then go to the Services > My Services tab, find your license key and reissue it. Then go to panel's Servers > Manage Servers tab, click the icon at settings column for open the license page and reactivate you license.
