We want to be able to handle crashes of either the GPU process, or the child process without crashing the other. If it's the GPU process that crashes, we want to resume decoding as soon as it's available again, probably from the next keyframe.

Comment on attachment 8806567 [details] [diff] [review] (lazily) Rebuild VideoDecoderManager when we restart the GPU process v3 Review of attachment 8806567 [details] [diff] [review]: ----------------------------------------------------------------- ::: dom/media/ipc/VideoDecoderManagerChild.cpp @@ +84,5 @@ > + RefPtr<VideoDecoderManagerChild> manager; > + RefPtr<Runnable> createManager = NS_NewRunnableFunction([&]() { > + Endpoint<PVideoDecoderManagerChild> endpoint; > + if (!ContentChild::GetSingleton()->SendInitVideoDecoderManager(&endpoint)) { > + return; return nullptr? (below too) slightly better form to have this function return RefPtr<VideoDecoderManagerChild>, but okay either way now that sDecoderManager is single-thread.
