Summary [Mac] DataCues do not work properly when rewinding video

If you play a video that has embedded WebKitDataCue elements, the cues are displayed properly as you watch the video. However, if you rewind the video, the data cues are not re-displayed.

This bug was introduced with Bug 132715 (Changeset <http://trac.webkit.org/changeset/168519>). 1. DataCue objects do not provide the correct startTimeVariance value for AVFoundation use. 2. The comparison in "hasEquivalentStartTime" should be "<=", rather than "<" to handle the case of zero startTimeVariance.

Comment on attachment 231796 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=231796&action=review Did you mean to mark this r? If so, this looks good to me modulo the TextTrack.h change I don't understand. > Source/WebCore/html/track/TextTrack.h:162 > + virtual double startTimeVariance() const { return 0; } > + Why is this needed?
