For now, the H264 decoding support is rather sturdy. It handles change of resolution and content smoothly thanks to the H264Converter.
The VP8/VP9 one however, not so much.
So we make a preference to only enable H264 for now.
Depends on D7895

Summary:
The fix of bug 1479964 breaks some web apps using Google Closure including
Google's apps. So, for Nightly testers, we should disable the new behavior
until Google Closure fixes it or we can disable the new behavior per web apps.

Chrome sets both KeyboardEvent.keyCode and KeyboardEvent.charCode of "keypress"
event to same value. On the other hand, our traditional behavior is, sets
one of them to 0.
Therefore, we need to set keyCode value to charCode value if the keypress
event is caused by a non-function key, i.e., it may be a printable key with
specific modifier state and/or different keyboard layout for compatibility
with Chrome. Similarly, we need to set charCode value to keyCode value if
the keypress event is caused by a function key which is not mapped to producing
a character.
Note that this hack is for compatibility with Chrome. So, for now, it's enough
to change the behavior only for "keypress" event handlers in web content. If
we completely change the behavior, we need to fix a lot of default handlers
and mochitests too. However, it's really difficult because default handlers
check whether keypress events are printable or not with following code:
> if (event.charCode &&
> !event.altKey && !event.ctrlKey && !event.metaKey) {
or
> if (!event.keyCode &&
> !event.altKey && !event.ctrlKey && !event.metaKey) {
So, until we stop dispatching "keypress" events for non-printable keys,
we need complicated check in each of them.
And also note that this patch changes the behavior of KeyboardEvent::KeyCode()
when spoofing is enabled and the instance is initialized by initKeyEvent() or
initKeyboardEvent(). That was changed by bug 1222285 unexpectedly and keeping
the behavior makes patched code really ugly. Therefore, this takes back the
old behavior even if spoofing is enabled.

Etherpad fixed the bug with new Gecko behavior and has already released
it in this August. So, even if some instances still use older versions,
we can request them to update the version.
This patch removes all Etherpad instances we know from the blacklist
of strict keypress dispatching. So, Nightly testers can find old
instances easier.

StructuredCloneTester objects can configured to be serializable (or not) and
deserializable (or not) by the structured clone algorithm. They can be used to
test, for example, onmessageerror event handlers, where the messageerror event
is fired when a message fails to be deserialized (but was successfully serialized).
The class is pref'ed with "dom.testing.structuredclonetester.enabled".

Medium's editor listens to keypress event to handle Ctrl+Z and Ctrl+Y on Gecko.
Therefore, if we don't dispatch keypress events for non-printable keys (by
default on Nightly), users cannot use undo/redo in medium.com.
This patch makes the editor of medium.com into the blacklist of strict
keypress dispatching for avoiding inconvenience of Nightly testers.

By delegating responsibility for shared surfaces reporting to imagelib,
we can cross reference the GPU shared surfaces cache with the local
surface cache in a content process (or the main process). This will
allow us to identify entries that are in the GPU cache but not in the
content/main process cache, and aid in debugging memory leaks. This
functionality is pref'd off by default behind image.mem.debug-reporting.
Additionally, we want to report every entry that was mapped into the
compositor process, in the compositor process memory report. This will
give us a sense of how much of our resident memory is consumed by mapped
images in absence of the more detailed cross referencing above.
