Hi Chen,
For modules/libimg/png, mozilla products use aPNG which was rejected
by upstream.
http://en.wikipedia.org/wiki/APNG
So we have to use internal png.
For media/libvorbis, mozilla has custom patches in the source tree.
https://bugzilla.mozilla.org/show_bug.cgi?id=517422
Fro media/libvpx, I don't know well. However you are welcome to file
the issue to bugzilla.mozilla.org.

Mozilla isn't always great about getting changes pushed upstream.
I just committed the relevant patch they had outstanding against
libvorbis to the libvorbis svn, though I'm not sure when we'll cut
another official libvorbis release.
(They also have a patch for building on Solaris— which seems to be due
to not using the normal build system for libvorbis. I'm pretty
confident that it's irrelevant for Fedora).

But this is against our packaging guidelines.
There are only 2 solutions to this:
a. apply the Debian patch which removes APNG support from xulrunner OR
b. apply the Mozilla patch which adds APNG support to libpng.
The current "solution" is NOT acceptable.

c. help create a real project out of http://littlesvr.ca/apng/ with
tarballs instead of just patchsets, possibly renaming it to something
else, and ship that so we can build against it.

How is shipping a redundant copy of essentially the same code better than just
applying the patch to our libpng package?
There's even an upstream for those patchsets, I really don't see why it can't
just be applied to our libpng.
I know that it's a nonstandard extension for PNG. In fact, I'm really angry at
Mozilla for having come up with that instead of promoting the already existing
MNG! But given the situation we have now, it's in the best interest of Fedora
as a distribution to ship an APNG-enabled libpng.
