[GStreamer] Support "chapter" text tracks
​https://bugs.webkit.org/show_bug.cgi?id=122000

Patch by Brendan Long <​b.long@cablelabs.com> on 2013-10-01
Reviewed by Eric Carlson.

Source/WebCore:

Test: media/track/in-band/track-in-band-mkv-chapters.html

  • platform/graphics/gstreamer/InbandMetadataTextTrackPrivateGStreamer.h: New class, needed for cues that aren't associated with GstPads.
  • platform/graphics/gstreamer/MediaPlayerPrivateGStreamer.cpp:

(WebCore::MediaPlayerPrivateGStreamer::handleMessage): Check for table of contents messages.
(WebCore::MediaPlayerPrivateGStreamer::processTableOfContents): Parse table of contents messages into text tracks.
(WebCore::MediaPlayerPrivateGStreamer::processTableOfContentsEntry): Recursive method for parsing all of the TOC entries.

  • platform/graphics/gstreamer/MediaPlayerPrivateGStreamer.h: Add the processTableOfContents functions.

LayoutTests:

  • media/content/counting-subtitled-srt.mkv: Added chapters metadata.
  • media/track/in-band/track-in-band-mkv-chapters-expected.txt: New test, similar to cues-added-one, but uses "chapters" track.
  • media/track/in-band/track-in-band-mkv-chapters.html: Same.
  • media/in-band-cues.js: Updated tests to handle the new "chapters" track.

     10        * platform/graphics/gstreamer/InbandMetadataTextTrackPrivateGStreamer.h: New class, needed for cues that aren't associated with GstPads.
     11        * platform/graphics/gstreamer/MediaPlayerPrivateGStreamer.cpp:
     12        (WebCore::MediaPlayerPrivateGStreamer::handleMessage): Check for table of contents messages.
     13        (WebCore::MediaPlayerPrivateGStreamer::processTableOfContents): Parse table of contents messages into text tracks.
     14        (WebCore::MediaPlayerPrivateGStreamer::processTableOfContentsEntry): Recursive method for parsing all of the TOC entries.
     15        * platform/graphics/gstreamer/MediaPlayerPrivateGStreamer.h: Add the processTableOfContents functions.
