+++ This bug was initially created as a clone of Bug #950079 +++ This bug is created based on Bug 950079 Comment 17. Buffer ownership handling between SurfaceStream and CanvasClient has a problem. It could cause the problem to Fence delivery from Compositor to SurfaceStream.

CanvasClientSurfaceStream does not explicitly handle buffer return to SurfaceStream. Post new buffer to Compositor side by the following call implicitly expect synchronous buffer return to the SurfaceStream. But the following call requests async transaction. > GetForwarder()->UseTexture(this, mBuffer);
Bug 988956 might be necessary to fix the problem.
I am going to use AsyncTransactionTracker::WaitComplete() to wait transaction complete. http://mxr.mozilla.org/mozilla-central/source/gfx/layers/ipc/AsyncTransactionTracker.h

Confirmed the patch black flickering is fixed.

Comment on attachment 8424186 [details] [diff] [review] patch - Handle buffer ownership between SurfaceStream and CanvasClient. Review of attachment 8424186 [details] [diff] [review]: ----------------------------------------------------------------- I am struggling a bit with the logic around process ID, I suppose there is always one parent process so we don't really need to track its ID, so I suppose we are looking at the the child process ID here. But we create the LayerTransactionParent querying the current process ID, which makes it look like we are tracking the parent ID, so I am a bit confused. I think it would help a lot if you renamed all the [m|a]ProcessId and aOtherProcessID variables into [m|a][Child|Parent]ProcessId to make it clear which side's ID we are tracking. I'll catch up with you on irc or skype today to get a better understanding of the overall thing. ::: gfx/layers/client/TextureClient.h @@ +297,5 @@ > return mReleaseFenceHandle; > } > > /** > + * Set AsyncTransactionTracker of RemoveTextureFromCompositableAsync() transaction. nit: trailing space ::: gfx/layers/ipc/CompositableTransactionParent.cpp @@ +187,5 @@ > + GetProcessId(), > + OpReplyRemoveTexture(true, // isMain > + op.holderId(), > + op.transactionId())); > + nit: trailing spaces

The patch tracks child side's process id. When LayerTransactionParent(CompositableParentManager) receives an async transaction message, it sends back an async transaciton response message via ImageBridge parent. The messge is handled to ImageBridgeChild. ImageBridgeChild notify the transaction complete to AsyncTransactionTrackersHolder. By this way, AsyncTransactionTracker provide a sync wait capability by using async transaction. By changing the sync wait place from gecko ipc transaction to AsyncTransactionTracker, we could put off sync wait.
Apply the comments.

Attachment #8427041 - Flags: review+
On master, the problem is fixed. But on v1.4, the problem is exist on hw composer composition:-( On OpenGL composition case, the problem is fixed even in b2g v1.4. On current master, hw composer is not used in almost all situations by some reasons. On b2g v1.4, Hw composer is used in WMW app. If we disable the hw composer, the problem is gone with the patch.
Release Fences are always sent on main thread, but RemoveTextureAsync transaction response is sent via ImageBridge. Therefore, release fence is arrived to child side after the transaction response's receival in child side.
Need to send related Fence object via ImageBridge too.
I locally fixed the black flash problem in Comment 31. But it change how to deliver Fence from compositor to child side. More code change becomes necessary. I am updating the patch.
Patch for b2g v1.4. Fix flickering problem on HWComposer composition.

This is causing a B2G OS crash when I try to make a webrtc call using H.264 OMX. It works on the checkin before this landed (my patches for OMX H.264 cleanup landed a few hours after this, and had been tested before this landed). I reverified using the pre-checkin patches and this rev and the previous rev; previous rev works, this one crashes the phone. You need this: pref("media.peerconnection.video.h264_enabled", true); or equivalent user pref to enable it. We'll need to back this out or land a fix very soon.
Thanks for the notification. I am going to check it soon.

Hmm, b2g v1.4 does not have Bug 924622 fix. It might affect to the crash.
FWIW, I'm trying to talk nical into writing backport patches for 30 and 31 :)
The crash happens because there is a cases that ImageBridgeParent is not destroyed until nsCycleCollector_shutdown(). I am going to add a workaround to prevent the crash for b2g-v1.4.

FYI, you can safely ignore the mochitest-e10s and Android debug results (they were never intended to run on Gecko 30 anyway). As a general rule of thumb, you can safely ignore any test results for things you don't see running on a normal b2g30 run on TBPL.
