Report that we can play MP3 inside MP4 on Windows Vista and later in
HTMLMediaElement.canPlayType. Chrome and IE on Windows match this behaviour.
Add a test file with MP3 contained inside MP4. Note the B2G emulator can't play
this file, so I added a codecs parameter to the file's mime type so that
decoder backends have to opt-in to testing with it.
Enable playback of MP3 inside MP4 in WMFReader.
Change from reporting the IMFSourceReader's duration inside WMFReader, to
instead report the IMFSourceReader's duration as the media "end time". This is
needed because the MP3-contained-in-MP4 file's first sample output by the
IMFSourceReader has a non-zero timestamp, and the MediaDecoderStateMachine
assumes that the media samples will be in the range
[$firstSampleStartTime, $firstSampleStartTime+$reportedDuration]. But that's
not the case here, the IMFSourceReader seems to output samples in the range
[0,$reportedDuration]. This assumption mismatch means on the
MP3-contained-in-MP4 file we end up trying to seek after what the
IMFSourceReader assumes is the end of the file, which fails and causes
test failures.

Diego's README changes
update tests
Two comments in AnimationCommon.h refer to 'mFlushCount' which was presumably
the old name for mAnimationGeneration. Also, one comment says
nsCSSFrameConstructor tracks this. This patch adjusts the comments to refer
to mAnimationGeneration and RestyleManager.
(The reference to nsTransitionManager::UpdateAllThrottleStyles() is still valid
since there is useful documentation accompanying that method despite the fact
that the relevant code is mostly contained in AnimationCommon.h since bug
914847. Eventually we will unify the structures of transitions and
animations to the the point that we can replace the
IMPL_UPDATE_ALL_THROTTLED_STYLES_INTERNAL macro in AnimationCommon.h with an
actual method. At that point we can move the documentation accompanying
nsTransitionManager::UpdateAllThrottleStyles and its references to
AnimationCommon.)
We need a basic representation of animations from which we can derive subclasses
to represent specific cases such as transitions. For now we will retrofit
ElementAnimation for that purpose hence renaming it to StyleAnimation.
This patch removes the "using namespace mozilla::layers" line from
AnimationCommon.cpp since the unified build system concatenates several files
together before compiling making using declarations like this leak into other
files potentially creating ambiguities. Previously, when we were calling
ElementAnimation, 'Animation', there were ambiguities between
mozilla::layers::Animation and this new 'Animation' class. In general, it is
probably a good idea to limit the scope of these using declarations so I've kept
that change.
This patch relocates ElementAnimation from nsAnimationManager.{h,cpp} to
AnimationCommon.{h,cpp} and in the process moves it into the mozilla::css
namespace.
The loops for adding animations and transitions to a layer in
nsDisplayList::AddAnimationsAndTransitionsToLayer are now identical and so can
be factored out into a common method.
Since it is not possible to implicitly convert from
nsTArray<ElementPropertyTransition> to nsTArray<ElementAnimation> despite
ElementPropertyTransition being a subclass of ElementAnimation a templated
method is used. In the future, as animations and transitions share more and more
code, we should be able to remove the need for templates.
ElementAnimation::HasAnimationOfProperty doesn't seem to be overridden anywhere.
I suspect it was a copy-paste mistake because the methods of the same name on
ElementAnimations, ElementTransitions, and CommonElementAnimationData are
virtual.
Now that ElementTransitionProperty inherits from ElementAnimation,
ElementTransitions::HasAnimationOfProperty can re-use
ElementAnimation::HasAnimationOfProperty in its definition of
ElementTransitions::HasAnimationOfProperty.
Similarly, in nsDisplayList::AddAnimationsAndTransitionsToLayer we can use this
method rather than drilling down to the appropriate segment by hand.
Both ElementPropertyTransition and ElementAnimation specify an IsRunningAt
method which have the same purpose but with two subtle differences:
a) ElementPropertyTransition::IsRunningAt checks if the transition is a removed
sentinel and if so returns false. This patch adds a check for a null start time
to IsRunningAt since I think in future we will want to allow null times in
various places to represent, for example, animations that are not connected to
a timeline. (However, ultimately we will probably not allow start times on
*animations* to be null, only on their associated player.)
Should we later use a different mechanism for marking sentinel transitions (e.g.
a boolean flag) this method should still be correct as it checks if aTime is
inside the transition interval before returning true.
b) ElementPropertyTransition::IsRunningAt returns false if the transition is in
the delay phase, that is, waiting to start. This patch changes this behavior so
that transitions are considered running even if they are in the delay phase.
This brings their behavior into line with animations and removes the need for
the ElementPropertyTransition::mIsRunningOnCompositor since it is only used to
determine when a transition in the delay phase has begun.
ElementAnimation::IsRunningAt also handles pause state and iterations but this
logic should still be correct for transitions which, in this area, only use
a subset of the functionality of animations since their pause state is always
playing and their iteration count is 1.
As part of moving towards more shared data structures for animation, this patch
makes ElementPropertyTransition inherit from ElementAnimation. At the same time
we switch from storing the target property, start/end values, start time, delay,
and timing function on the transition to the corresponding location in
ElementAnimation.
Since nsDisplayList::AddAnimationsAndTransitionsToLayer was already doing this
conversion in order to create animations to pass to the compositor thread, we
can remove the conversion code from there and just use the ElementAnimation data
structures as-is.
A number of assertions are added to verify that transitions are set up as
expected (namely, they have only a single property-animation with a single
segment). As we move to more generic handling of animations and transitions
these assertions should disappear.
As a first step towards making CSS animations and CSS transitions use the same
data structures, this patch aligns their behavior with regards to start time and
delay handling.
Previously, ElementAnimation objects maintained separate mStartTime and mDelay
members whilst ElementPropertyTransition objects maintained a single mStartTime
property that incorporated the delay. This patch adds an mDelay member to
ElementPropertyTransition and stores the delay and start time separately.
Calculations involving ElementPropertyTransition::mStartTime are adjusted to
incorporate mDelay.
