[Bug 967091] Re: Wrong tint in flash when it uses video acceleration

 

I'd like to get the existing bugfix accepted as an SRU. Hope I get the
SRU process more or less right.

While simply using the Quantal revision's changes in Precise would work
perfectly well, I also created an update for the Precise version that
includes only patches relevant for this bug. See the linked bzr branch
and debdiff.

** Description changed:

  Using Ubuntu 11.10 64 bit, nvidia binary driver, youtube videos show blue faces after the upgrade to flashplugin 11.2.
  Didn't occur with 11.1.

+ SRU description
+ 
+ [IMPACT]
+ 
+  * Flash videos have the wrong tint ("blue faces") on Precise when
+    using nvidia-current or nvidia-current-updates.
+ 
+  * This effectively renders Flash videos unwatchable for all LTS users
+    with an NVidia video card.
+ 
+ [TESTCASE]
+ 
+  * Install nvidia-current, view any Flash video on YouTube,
+    eg. https://www.youtube.com/watch?v=dkVBXW4JeUI.
+ 
+  * Reproducable with various Nvidia video cards from at least the
+    GeForce 8 series up to the GeForce 600 series.
+ 
+  * Screenshot included in Aloysius' original bug description.
+ 
+ [Regression Potential]
+ 
+  * While Stephen Warren's patch is not exactly a one-liner, it is
+    rather straightforward and only changes libvdpau's behaviour for
+    Flash.
+ 
+  * On the off-chance that this change causes instability, it can be
+    easily disabled via vdpau_wrapper.cfg.
+ 
+  * The patch is widely tested, is included in upstream since 0.5 and
+    has been backported for 0.4.1 by the Debian team. The fix is
+    included in Quantal (0.4.1-6ubuntu1).
