--- Comment #3 from Hyunjun Ko <zzoon at igalia.com> ---
This deadlock happens when seek is called on the main thread, which also has to call back for resource loader (dataReceived, responseReceived) 

In OGG demuxer during seek, it requests more data to upstream if needed, but between appsrc and ogg demuxer in this case, there's downloadbuffer, which is waiting for upstream's feeding.

But at the moment appsrc(webkitwebsrc) can't feed since seek is not finished. Because dataReceived can't be called until seek finishes.
