97 * AudioMapping XML changed.
99 * Subtitle offset changed to subtitle y offset, and subtitle x offset added.
101 * Use <Scale> tag in <VideoContent> rather than <Ratio>.
105 * Subtitle X and Y scale.
107 * Bumped to 32 for 2.0 branch; some times are expressed in Times rather
111 * Changed <Period> to <Subtitle> in FFmpegSubtitleStream
113 * Content only contains audio/subtitle-related tags if those things
116 * VideoFrameType in VideoContent is a string rather than an integer.
118 * EffectColour rather than OutlineColour in Subtitle.
