+
+ Handle changing playback rate
+ Before this patch, NLE and GES did not support NleOperations (respectively
+ GESEffects) that changed the speed/tempo/rate at which the source plays. For
+ example, the 'pitch' element can make audio play faster or slower. In GES 1.5.90
+ and before, an NleOperation containing the pitch element to change the rate (or
+ tempo) would cause a pipeline state change to PAUSED after that stack; that has
+ been fixed in 1.5.91 (see #755012 [0]). But even then, in 1.5.91 and later,
+ NleComposition would send segment events to its NleSources assuming that one
+ source second is equal to one pipeline second. The resulting early EOS event
+ (in the case of a source rate higher than 1.0) would cause it to switch stacks
+ too early, causing confusion in the timeline and spectacularly messed up
+ output.
+ This patch fixes that by searching for rate-changing elements in
+ GESTrackElements such as GESEffects. If such rate-changing elements are found,
+ their final effect on the playing rate is stored in the corresponding NleObject
+ as the 'media duration factor', named like this because the 'media duration',
+ or source duration, of an NleObject can be computed by multiplying the duration
+ with the media duration factor of that object and its parents (this is called
+ the 'recursive media duration factor'). For example, a 4-second NleSource with
+ an NleOperation with a media duration factor of 2.0 will have an 8-second media
+ duration, which means that for playing 4 seconds in the pipeline, the seek
+ event sent to it must span 8 seconds of media. (So, the 'duration' of an
+ NleObject or GES object always refers to its duration in the timeline, not the
+ media duration.)
+ To summarize:
+ * Rate-changing elements are registered in the GESEffectClass (pitch::tempo and
+ pitch::rate are registered by default);
+ * GESTimelineElement is responsible for detecting rate-changing elements and
+ computing the media_duration_factor;
+ * GESTrackElement is responsible for storing the media_duration_factor in
+ NleObject;
+ * NleComposition is responsible for the recursive_media_duration_factor;
+ * The latter property finally fixes media time computations in NleObject.
+ NLE and GES tests are included.
