1.4.0 (2015-07-06)

Code health release. Major refactoring of streaming logic.

Bugfixes:

  • Overriding a license server URL in the test app no longer causes a PSSH from the MPD to be ignored.
  • Fixed possible event listener leak.

Features:

  • Player.destroy() now returns a Promise.
  • DrmSchemeInfo now has distinctiveIdentifier, persistentState, and robustness parameters.
  • Clarified buffering event policies.

  • Custom BandwidthEstimators can now allow XHR caching.
  • Added support for startNumber of 0, per the recent DASH spec corrigendum.
  • Added support for server certificate APIs through DrmSchemeInfo.
  • Major refactor of streaming. Switching representations is now faster and more flexible. Live stream seek ranges are more accurate.
  • XHR timeout is now runtime-configurable.
  • Buffering goals are now runtime-configurable.
  • Alternative IAbrManager implementations can now be injected at runtime.

Test app features:

  • Added "buffered ahead" and "buffered behind" indicators.
  • Converted cycle buttons into checkboxes so cycling can be stopped during playback.
  • Test app now jumps to live when the user clicks on the time code in a live stream.
  • Added an example of a trick-play UI built on the Player API.

Testing:

  • Disabled code coverage stats in unit tests by default.
  • Split unit tests and integration tests into separate test runners.

  • Improved documentation for Role tags and multilingual assets.

Test app features:

  • Example player controls in the test app.

Deprecated:

  • The following methods on Player are deprecated. They will be removed in v1.4.0:
    • getCurrentResolution() (replace with video.videoWidth & video.videoHeight)
    • getCurrentTime()/seek() (replace with video.currentTime)
    • getDuration() (replace with video.duration)
    • getMuted()/setMuted() (replace with video.muted)

    • play() (replace with video.play)
    • pause() (replace with video.pause)
    • requestFullscreen() (replace with video.requestFullscreen())

Broken compatibility:

  • The license postprocessor callback is no longer given a Restrictions argument. See Player.getRestrictions()/setRestrictions().

1.2.2 (2015-03-11)

A roll-up of recent bugfixes, plus a few minor additions to the test app. Branched from v1.2.0.

Bugfixes:

  • Try to recover from a streaming failure.
  • Ignore spurious error events from the video tag.
  • Update docs WRT content restrictions and folder organization.
  • Fix clearkey errors in Chrome 42+.

    • Only affects assets which use SegmentTemplate with a duration attribute.

Test app features:

  • Rename a confusing asset.
  • Add a button to cycle video tracks.
  • Support MPD init data overrides for all DRM schemes.

1.2.0 (2015-02-24)

Lots of internal refactoring and bugfixes, and a few new features.

Bugfixes:

  • Buffer eviction no longer causes hangs on seek.
  • Adaptation no longer causes hangs on looping and seeking backward.
  • StreamStats no longer shows null for width and height before adaptation.
  • Content with differing start times for the audio & video streams no longer exhibits A/V sync issues.
  • DrmSchemeInfo's suppressMultipleEncryptedEvents flag is now correctly honored regardless of the timing of events.
  • Calculations for the $Time$ placeholder in MPD SegmentTemplates has been corrected.
  • The test app no longer causes mixed-content errors when served over HTTPS.
  • Small mistakes in URLs and asset names in the test app have been corrected.
  • Windows checkouts now have consistent newline style.
  • Windows build steps documented.

Features:

  • The isTypeSupported polyfill has been removed and all EME APIs have been updated to the Feb 9 2015 EME spec.
  • Gaps and overlaps in SegmentTimeline are no longer treated as an error. Large gaps/overlaps will still generate a warning.
  • HDCP-related failures are now translated into error events in Chrome 42+.
  • The MPD Role tag is now supported as a way of indicating the main AdaptationSet for the purposes of language matching.

  • Parser support for the new v1 PSSH layout, including parsing of key IDs.
  • The fullscreen polyfill has been updated and expanded.
  • DashVideoSource refactored to split DASH-independent functionality into the generic StreamVideoSource. This should simplify the implementation of new video sources for non-DASH manifest formats. (Contributions welcome.)
  • Automatic build numbering has been added, with version numbers appearing in the test app UI.
  • The library has been published on npm and cdnjs.
  • Release version numbering follows the semantic versioning spec.

Broken Compatibility:

  • System IDs in PSSH objects are now hex strings instead of raw strings.

    • language preference
    • license restrictions
    • WebM/VP9
    • error events
  • Integration tests now run much faster.
  • MediaKeys polyfills have received minor updates to improve compatibility with Chrome 41.
