Any news on this one? Straightforward change

@kkroening

Have you already tested the code?
I used the same fix, but problem still exists.

@ArchieMeng could you check with the latest version? I changed it slightly to cover all cases.

I tested in my use case, which is:

        self._ffmpeg_proc = (
            ffmpeg.input("pipe:", format="rawvideo", pix_fmt="yuyv422", s=resolution, framerate=cfg().calculate_fps())
            .output(self._filename, vcodec=cfg().record_codec)
            .overwrite_output()
            .run_async(pipe_stdin=True, quiet=True)
        )

Patched and running fine in v0.2.0. Here's how run_async is being called:

def run(self):
  """
  Run channel encoder
  """

  self.process = (
    self.output.run_async(
      quiet=self.quiet
    )
  )
  self.print("Running")

  return_code = self.process.wait()
  if return_code:
    self.print(f"Exited with code {return_code}")

Just for the record, the secret here is to redirect stderr to stdout and then redirect stdout to /dev/null, otherwise, it doesn't work redirecting both to /dev/null.

That's a weird bug 🤔

Yes. It works. Thank you.
