dash.js v4.6.0 officially released

[daniel....@fokus.fraunhofer.de]

Hello all,

we are pleased to announce that version 4.6.0 of dash.js has officially been released.

A big thank you to all the contributors that made this possible, especially Bertrand Berthelot.

The release info can be found here:

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
• #4095 Add feature support for Common Media Server Data. 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
    

Improvements

• #4102 Use Karma as a testrunner for the unit tests. Allows us to run the tests in "real" browser-based environments and not in node.js context
• #4103 #4412 Fix blinking cues when segmented over multiple segments or chunks
• Link Add unit test for Utils.parseHttpHeaders
• Link Remove deployment script from Circle CI/CD
• Link Remove http rewrite on the default timing source
• Link Improve error message for missing ttml rendering div
• Link Update browser tools for Circle CI to version 1.4.1
  

Bugfixes

• #4101 Fix handling of embedded texttracks for dynamic streams with MPD updates
• #4107 Fixes an issue when the timescale value in the manifest differs from the timescale in init segments
• #4110 Corrected fallback responseHeaders value to be null
• #4418 Move ContentSteeringController configuration initialization to initialize function to fix error in offline playback
• Link Fix a regression when providing a posix string as start value to attachSource()

One addition that is missing in the release notes above:

#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.
