/* Convert from an internal time of a child within a clip to a
|
||||
* ===========================================================
|
||||
* timeline time
|
||||
* =============
|
||||
*
|
||||
* Given an internal time T for some child in a clip, we want to know
|
||||
* what the corresponding time in the timeline is.
|
||||
*
|
||||
* If the time T is between the in-point and out-point of the child,
|
||||
* then we can convert to the timeline coordinates by answering:
|
||||
*
|
||||
* a) "What is the timeline time at which the internal data from the child
|
||||
* found at time T appears in the timeline output?"
|
||||
*
|
||||
* If the time T is after the out-point of the child, we instead want to
|
||||
* answer:
|
||||
*
|
||||
* b) "If we extended the clip indefinetly in the timeline, what would be
|
||||
* the timeline time at which the internal data from the child found at
|
||||
* time T would appear in the timeline output?"
|
||||
*
|
||||
* However, if the time T is before the in-point of the child, we instead
|
||||
* want to answer a more subtle question:
|
||||
*
|
||||
* c) "If we set the 'in-point' of the child to T, what would we need to
|
||||
* set the 'start' of the clip to such that the internal data from the
|
||||
* child currently found at the *beginning* of the clip would then appear
|
||||
* at the same timeline time?"
|
||||
*
|
||||
* E.g. consider the following children of a clip, all in the same track,
|
||||
* and all active:
|
||||
* T
|
||||
* :

|
||||
* -------------------------------:-------------------timeline
|
||||
* S X
|
||||
*
|
||||
* where i is the in-point of the source and i' is the in-point of the
|
||||
* overlay. Also, g0 is the sink_to_source translation function for the
|
||||
* first time effect, and g1 is the same for the second. S is the start of
|
||||
* the clip. The ~(o_o)~ figure is the data that appears in the source at
|
||||
* T.
|
||||
*
|
||||
* Essentially, question a) wants us to convert from the time T, where the
|
||||
* data is, which is in the internal time coordinates of the source, to
|
||||
* the timeline time X. First, we subtract i to convert from the internal
|
||||
* source coordinates of the source to the external source coordinates of
|
||||
* the source, then we apply the sink_to_source translation functions,
|
||||
* which act on external source coordinates, then add 'start' to finally
|
||||
* convert to the timeline coordinates. So overall we have
|
||||
*
|
||||
* X = S + g1(g0(T - i))
|
||||
*
|
||||
* To answer b), T would be beyond the end of the clip. Since g1 and g0
|
||||
* can convert beyond the end time, we similarly compute
|
||||
*
|
||||
* X = S + g1(g0(T - i))
|
||||
*
|
||||
* The user themselves should note that this could exceed the max-duration
|
||||
* of any of the children.
|
||||
*
|
||||
* Now consider
|
||||
*
|
||||
* T
|

* ---:-----------------------------------------------timeline
|
||||
* X S
|
||||
*
|
||||
* To do the same as a), we would need to be able to convert from T to X,
|
||||
* but this isn't defined since the children do not extend to here. More
|
||||
* specifically, the functions g0 and g1 are not defined for negative
|
||||
* times. Instead, we want to answer question c). That is, we want to know
|
||||
* what we should set the start of the clip to to keep the figure at the
|
||||
* same timeline position if we change the in-point of the source to T.
|
||||
*
|
||||
* First, if we set the in-point to T, then we would have
|
||||
*
|
||||
* T
|
||||
* :
|
||||
* +============================+
|
||||
* | _/ \_ |
|
||||
* | ~(o_o)~ source |

|
||||
* : :
|
||||
* ---:-----:-----:-----------------------------------timeline
|
||||
* X S Y
|
||||
*
|
||||
* In order to make the figure appear at 'start' again, we would need to
|
||||
* reduce the start of the clip by the difference between S and Y, where
|
||||
* Y is the conversion of the previous in-point i to the timeline time.
|
||||
*
|
||||
* Thus,
|
||||
*
|
||||
* X = S - (Y - S)
|
||||
* = S - (S + g1(g0(i - T)) - S)
|
||||
* = S - g1(g0(i - T))
|
||||
*
|
||||
* If this would be negative, the conversion will not be possible.
|
||||
*
|
||||
* Note, we are relying on the *assumption* that the translation functions
|
||||
* *do not* change when we change the in-point. GESBaseEffect only claims
|
||||
* to support such time effects.
|
||||
*
|
||||
* Note that if g0 and g1 are simply identities, and we translate the
|
||||
* internal time using a) and b), we calculate
|
||||
*
|
||||
* S + (T - i)
|
||||
*
|
||||
* and for c), we calculate
|
||||
*
|
||||
* S - (i - T) = S + (T - i)
|
||||
*
|
||||
* In summary, if we are converting from internal time T to a timeline
|
||||
* time the return is
|
||||
*
|
||||
* G(T) = { S + g1(g0(T - i)) if T >= i,
|
||||
* { S - g1(g0(i - T)) otherwise.
|
||||
*
|
||||
* Note that the overlay did not play a role since it overall translates
|
||||
* all received times by the identity. Note that we could similarly want
|
||||
* to convert from an internal time in the overlay to the timeline time.
|
||||
* This would be given by
|
||||
*
|
||||
* S + g1(T - i') if T >= i',
|
||||
* S - g1(i' - T) otherwise.
|

*
|
||||
* Convert from a timeline time to an internal time of a child
|
||||
* ===========================================================
|
||||
* in a clip
|
||||
* =========
|
||||
*
|
||||
* We basically want to reverse the previous conversion. Specifically,
|
||||
* when the timeline time X is between the start and end of the clip we
|
||||
* want to answer:
|
||||
*
|
||||
* d) "What is the internal time at which the data from the child that
|
||||
* appears in the timeline at time X is created in the child?"
|
||||
*
|
||||
* If the time X is after the end of the clip, we instead want to answer:
|
||||
*
|
||||
* e) "If we extended the clip indefinetly in the timeline, what would be
|
||||
* the internal time at which the data from the child that appears in the
|
||||
* timeline at time T would be created in the child?"
|
||||
*
|
||||
* However, if the time X is before the start of the child, we instead
|
||||
* want to answer:
|
||||
*
|
||||
* f) "If we set the 'start' of the clip to X, what would we need to
|
||||
* set the 'in-point' of the clip to such that the internal data from the
|
||||
* child currently found at the *beginning* of the clip would then appear
|
||||
* at the same timeline time?"
|
||||
*
|
||||
* Following the same arguments, these would all be answered by
|
||||
*
|
||||
* F(X) = { i + f0(f1(X - S)) if X >= S,
|
||||
* { i - f0(f1(S - X)) otherwise.
|
||||
*
|
||||
* where f0 and f1 are the corresponding source_to_sink translation
|
||||
* functions, which should be close reverses of g0 and g1, respectively.
|
||||
*
|
||||
* Note that this does indeed reverse the internal to timeline conversion:
|
||||
*
|
||||
* F(G(T)) = { i + f0(f1(G(T) - S)) if G(T) >= S,
|
||||
* { i - f0(f1(S - G(T))) otherwise.
|
||||
*
|
||||
* but, since g1 and g0 map from [0,inf) to [0,inf),
|
||||
*
|
||||
* G(T) - S = { + g1(g0(T - i)) if T >= i,
|
||||
* { - g1(g0(i - T)) otherwise.
|
||||
* { >= 0 if T >= i,
|
||||
* { = 0 if (T < i and g1(g0(i - T)) = 0)
|
||||
* { < 0 otherwise.
|
||||
*
|
||||
* => ( G(T) >= S <==> T >= i or (T < i and g1(g0(i - T)) = 0) )
|
||||
*
|
||||
* therefore
|
||||
* F(G(T)) = { i + f0(f1(g1(g0(T - i)))) if T >= i,
|
||||
* { i + f0(f1(0)) if T < i
|
||||
* { and g1(g0(i - T)) = 0,
|
||||
* { i - f0(f1(g1(g0(i - T)))) otherwise
|
||||
*
|
||||
* = { i + f0(f1(g1(g0(T - i)))) if T >= i,
|
||||
* { i - f0(f1(g1(g0(i - T)))) otherwise
|
||||
*
|
||||
* = T
|
||||
*
|
||||
* because f1 reverses g1, and f0 reverses g0.

* particular scene in a media file.
|

*
|

* Note that whilst a clip has no time effects, this second return is

* equivalent to finding the timeline time at which the content of @child

|

*
|
||||
* ## Time Coordinates
|
||||
*
|
||||
* There are three main sets of time coordinates to consider when using
|
||||
* timeline elements:
|
||||
*
|
||||
* + Timeline coordinates: these are the time coordinates used in the
|
||||
* output of the timeline in its #GESTrack-s. Each track share the same
|
||||
* coordinates, so there is only one set of coordinates for the
|
||||
* timeline. These extend indefinitely from 0. The times used for
|
||||
* editing (including setting #GESTimelineElement:start and
|
||||
* #GESTimelineElement:duration) use these coordinates, since these
|
||||
* define when an element is present and for how long the element lasts
|
||||
* for in the timeline.
|
||||
* + Internal source coordinates: these are the time coordinates used
|
||||
* internally at the element's output. This is only really defined for
|
||||
* #GESTrackElement-s, where it refers to time coordinates used at the
|
||||
* final source pad of the wrapped #GstElement-s. However, these
|
||||
* coordinates may also be used in a #GESClip in reference to its
|
||||
* children. In particular, these are the coordinates used for
|
||||
* #GESTimelineElement:in-point and #GESTimelineElement:max-duration.
|
||||
* + Internal sink coordinates: these are the time coordinates used
|
||||
* internally at the element's input. A #GESSource has no input, so
|
||||
* these would be undefined. Otherwise, for most #GESTrackElement-s
|
||||
* these will be the same set of coordinates as the internal source
|
||||
* coordinates because the element does not change the timing
|
||||
* internally. Only #GESBaseEffect can support elements where these
|
||||
* are different. See #GESBaseEffect for more information.
|
||||
*
|
||||
* You can determine the timeline time for a given internal source time
|
||||
* in a #GESTrack in a #GESClip using
|
||||
* ges_clip_get_timeline_time_from_internal_time(), and vice versa using
|
||||
* ges_clip_get_internal_time_from_timeline_time(), for the purposes of
|
||||
* editing and setting timings properties.
