Took a look, parseNextChunk eventually calls push{Video,Audio}Frame
which in turn (in base class) calls waitIfNeeded (having the
AV queue already locked).
Your patch seems fine, and could eventually also make the call
to waitIfNeeded deep in pushAVFrame needless.
Watch out for deadlocks, if you don't get any go ahead and commit
it for broader testing.
