579919 - Quicktime flickering

Status: RESOLVED WORKSFORME

(Core Graveyard :: Plug-ins, defect)

Description

[Jeff Muizelaar [:jrmuizel]]

Playing the videos on this page http://www.apple.com/antenna/ with trunk on 10.5 causes a great deal of flickering. Safari doesn't have the same problem.

->benwa for investigation: did this start with retained layers?

Comment 2

[Benoit Girard (:BenWa)]

Also I'm wondering if the CoreAnimation rendering model is being negotiated by Quicktime. I have heard that there are some issues with CoreAnimation on 10.5.

I don't have a 10.5 machine. Can someone investigate if this was caused by Core Animation or retained layers landing?

This is also broken in 3.6 nightlies but fixed when you change the user-agent to firefox. It uses a different video player for Firefox perhaps.

3.5 shows the player and then crashes when you give the site an unexpected useragent.

Since we've had this problem for a long time it probably doesn't block anymore. However, it would still be good to figure out what's going on here.

I don't have access to a 10.5 machine at the moment so I'm un-assigning myself.

At this point it would be great to reconfirm this bug.

I don't see any flickering in today's mozilla-central nightly, testing
with the main video at http://www.apple.com/antenna/ on OS X 10.5.8.
(Click on "Watch the video" to start the video.)

Do you still see this problem, Jeff?  If so, please provided detailed
information on how to reproduce it.

I couldn't reproduce this issue on Mac OS 10.8 for FF 17 and Latest Nightly (12/12/2012)
