Example remux.py failed

Expected behavior

Got remuxed video

Actual behavior

Traceback:

  File "/Users/xizhen.liu/Downloads/test2.py", line 10, in <module>
    out_stream = output.add_stream(template=in_stream)
  File "av/container/output.pyx", line 47, in av.container.output.OutputContainer.add_stream
TypeError: add_stream() takes at least 1 positional argument (0 given)

Investigation

I tried using add_stream_from_template(). It runs successfully but the output video is not playable
