Status: RESOLVED DUPLICATE of bug 1436117

(Core :: WebRTC: Audio/Video, defect, P1)

Description

[Nils Ohlmeier [:drno]]

Example report https://crash-stats.mozilla.com/report/index/5ca8ebf7-1448-49a5-afb7-929df1180110

Would be interested in seeing if updating libyuv in bug 1346291 will fix this.

all wildptr reads -- though mostly ending in 0x00001, but not all.  Arguably sec-moderate, but to be consistent sec-high.

It's unlikely that the source of the problem is libyuv; most likely it's a race or logic flaw in webrtc/.../vp8_impl.cc or something above it in the stack.

Jan-Ivar, what is the next step here?

[Jan-Ivar Bruaroey [:jib] (needinfo? me)]

Thanks Frederik for the ping. CCing some folks. Looks like encoding. Jean-Yves, can you take a look?

Could this be bug 1436117 in effect?

Looks plausible as I only see a single crash in 60 from a date before the patch in bug 1436117 landed. Let's wait for 60 to become release and see if we will get any crash reports for it.

[Frederik Braun [:freddy]]

No crashes for recent releases. This one here *might* be RESOLVED/WORKSFORME.

Marking as dup
