Hmmm.. do you mean pushing downstream events serialized with buffer stream?
If so, I think, this issue exists even now, without the patch, because AFAICT
all the calls to gst_pad_push_event() isn't protected by STREAM_LOCK, so
locking it for gst_pad_push() call doesn't seem to save the game.
Unfortunately, I don't have an idea how to solve it easily. We had some
thoughts on adding some multi-threaded-aware routines to GstVideoDecoder or to
subclass it for multi-threaded decoders, but all these are not too realistic
for now, I think.
