stdin is always flushed before yeilding. While this loses some potential
speedup by processing video output on cpu while the gpu is processing
the next batch of frames, it is likely incompatible with errors related
to metadata which could not be replicated. For now, stdin is flushed to
reduce the likelihood of regression.
Fixed a mistaken ordering in the batch_manager node causing the
unique_id to be overwritten.
Re-add the dummy count value to the batch manager node in js. Without
it, an error during the first batch step will result in teh batch
manager node not being marked as stale. Since the batch_manager node
exists only as an optional input, IS_CHANGED will never be called and
there must be some external change to ensure it is still marked stale
