this crash signature is showing up in 43 builds for the first time. the crash numbers are fairly low during the beta cycle, but since it's a regression i wanted to get it on file.
Component: Audio/Video → Audio/Video: Playback
Seems to have disappeared in 47. I guess we wait until 47 goes to beta.

Anthony --  This was found and marked by the bot on Friday as a carryover regression affecting Beta and Release back to Fx43.   Looks like it's a low volume crash and a NULL deref that we don't see until the Release gets to Beta.  (Looks like it affects only users who have older cards.) Can you prioritize this and decide when it needs to get into a Release?  Thanks.
Flags: needinfo?(ajones)
Too late for beta and as Maire points out it is pretty low volume even on release. Up to anthony and team if they want to fix this for 50/51.
Matt - if I read this correctly d3d9Manager->Init is null here:

  nsAutoPtr<D3D9DXVA2Manager> d3d9Manager(new D3D9DXVA2Manager());
  hr = d3d9Manager->Init(aFailureReason); <----
  if (SUCCEEDED(hr)) {	
    return d3d9Manager.forget();

Any idea what is happening?
Flags: needinfo?(ajones) → needinfo?(matt.woodrow)
Init() isn't virtual, so we can't really jump to the wrong place when calling it.

I suspect the contents of Init() have been inlined and the crash dump is doing a poor job of showing line numbers.

I'll grab the minidump soon and see if that shows anything useful.
Attached patch d3d9-null-crashSplinter Review
I'm not sure if this is just really old d3d9 versions, or broken dll's, but either way we shouldn't crash on it.
