dash.js v4.6.0

Features

• #4108 Adds the preload functionality to the current version of dash.js. The idea is to preload the media segments into the memory before attaching a video element and initializing the MSE. That way content can be preloaded on platforms that only have a single decoder and are currently displaying different content. As an example, this enables Broadcast-Broadband ad-insertion on HbbTV devices. @dsilhavy
• #4095 Add feature support for Common Media Server Data @bbert . Includes:
  • CMSD response headers parsing
  • Add settings to
    • Enable/disable CMSD parsing
    • Enable/disable use of "mb" maximum suggested bitrate (mb) as an upper-bound for the ABR algorithm
    • set the weight ratio to be applied on etp regarding measured bandwidth to determine throughput to be used by ABR throughput rule
  • Update reference sample to add CMSD settings configuration and to display bandwidth (measured, etp) metrics
• #4122 Adds the possibility to define a function that is called before segments are appended to the SourceBuffer. That way the application can modify the data if required. @dsilhavy
