1.2.2 (2015-03-11)

Bugfixes:

  • Version 1.2.1 had multiple issues with its version numbering. These are now corrected, but npm requires unique version numbers to publish. Version 1.2.1 has been pulled from npm.

Features:

1.2.1 (2015-03-10)

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+.
  • Fix computation of the number of segments in MpdProcessor.
    • 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.
  • More detail added to AJAX error events.
  • The Player now dispatches buffering events.
  • 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.

1.1 (2015-01-14)

Maintenance release.

Bugfixes:

  • The enabled flag for text tracks is now preserved when switching tracks. Player.enableTextTrack() is no longer required after selectTextTrack().
  • The documentation for Player methods enableTextTrack, setPreferredLanguage, and getCurrentResolution has been corrected.
  • The AbrManager class is now correctly destroyed.
  • Clearkey support for Chrome 41+ has been fixed.
  • A new polyfill has been added to compensate for Chrome 41+'s removal of MediaKeys.isTypeSupported.
  • Several unused internal methods have been removed from the codebase.
  • Fixed a failing assertion in one of the MediaKeys polyfills.
  • Fixed failing code coverage analysis and related parse errors in several tests.
  • Fixed support for MPDs with SegmentTemplate@duration and MPD@mediaPresentationDuration, but no Period@duration attribute.

Features:

  • Tests are now checked for style.
  • Tests have been expanded to increase coverage and exercise more Player features:
    • playback rate
    • stats
    • 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.
  • New sample assets and code in app.js to demonstrate how to use a PSSH from an MPD to override what's in the content itself.

Broken Compatibility:

  • None!

1.0 (2014-12-19)

First public release.

Bugfixes:

  • Text tracks are no longer ignored in MPD manifests.
  • Adaptation decisions are now quicker and more reliable.
    • (This bug was more noticeable on faster internet connections.)
  • Playback no longer gets "stuck" on certain content.
  • Playback no longer gets "stuck" after certain seek patterns.
  • Player get/select/enable methods can now be called without a video source.
  • A <video> tag's "videoWidth"/"videoHeight" attributes now update correctly on Chrome >= 40.
  • Manual adaptation while paused no longer unpauses the video.
  • Credentials can now be used on cross-domain license requests.
  • Range headers are no longer sent for all segment requests.
    • (This fixes issues with IIS.)
  • A missing declaration of getVideoPlaybackQuality() has been added.
  • The compiled code no longer pollutes the global namespace.
  • DASH manifests using <SegmentList> are now parsed correctly.
  • Formatting has been fixed in the "Shaka Player Development" tutorial.

Features:

  • The Player is now reusable. You can call load() multiple times without calling destroy().
  • The JS linter is now included in sources, fixing compatibility issues between versions.
  • The test suite now includes playback integration tests.
  • The Player has been updated to support the 01 Dec 2014 draft of the EME specification.
  • The loader in load.js no longer makes assumptions about app.js. You can now use load.js to bootstrap other applications.
  • The test app now uses less screen real estate.
  • All custom events have been documented, and a new tutorial has been added to demonstrate how they can be used.
  • The Player now has a support-check API to determine if the browser has all necessary features for playback.
  • Sample code in the tutorials is now marked up to highlight changes from the previous sample.
  • Code coverage in unit tests has been increased.
  • Flakiness in unit tests has been reduced.
  • DASH manifests using <SegmentTemplate> without a segment index or segment timeline are now supported.
  • The DASH "presentationTimeOffset" attribute is now supported.

Broken Compatibility:
