Try run: https://treeherder.mozilla.org/#/jobs?repo=try&group_state=expanded&revision=3a9c5bb7753172459fde80e894388b4b809f0868

Test is no longer run after disabling.

I don't see how aarch64 EME could possibly be related to this test; it's likely another issue.

From a quick comparison of the $objdir/config.status of an i686 and an aarch64 build, I can see that MOZ_FFVPX is defined for i686, but not for aarch64. So that means that we'll always take the "flac not supported" branch here:
https://searchfox.org/mozilla-central/rev/b2d35912da5b2acecb0274eb113777d344ffb75e/dom/media/flac/FlacDecoder.cpp#19

This causes canPlayType() to report that we don't support flac.

This also mean our software vpX decoding will be using libvpx, which doesn't utilize parallelism as well as ffvpx.

thanks :cpearce, we assumed any playback was EME related, that is our fault- do you know who could look at this instead?

Comment 5

[Chris Pearce [:cpearce (Not reading bugmail)]]

I've filed bug 1533598 to look into the underlying cause. Once that's resolved, we can re-enable the test.

thanks for your help on this. There are a lot of failures and we are doing our best to aggregate them to be useful- this certainly helps!

Attachment: Bug 1526080 - re-enable some of the disabled media-related tests on windows10-aarch64

Comment 8

[Jean-Yves Avenard [:jya]]

fly by fix as I spotted the bug in bug 1674043

Comment 9

[Jean-Yves Avenard [:jya]]

will take this in bug 1674043 as it relies on a bug fixed there.

Comment 10

[Jean-Yves Avenard [:jya]]

flac is now enabled on arm64 platforms.
