I가 다음 코드 조각 :파이썬에서 내 Gstreamer 파이프 라인 논리에 근본적인 문제가 있습니다. 어떤 충고?

을하지만, 내가 제대로하고 있어요 있는지 확실하지 않습니다 :
는https://stackoverflow.com/a/18228933/814221
사람은 나를 이해하는 데 도움이 내가 잘못 근본적으로 뭘하는지?
감사합니다.
@HarvardGraff가이 질문에이 글을 올렸습니다. (현재 나와 다른 질문에 링크되어 있습니다.) 내 생각이 있다면 내 친구에게 알려줘! –
내 대답을 보았습니까? –
@HavardGraff 헤이 맨, 네, def는 당신의 대답을 보았습니다. 나는이 시점에서 생각하는 파이썬과 관련된 근본적인 문제를 가지고있었습니다. 귀하의 지침에 따라, 여기 내 개정 된 listener.py : http://pastebin.com/5paUJ9MS, recorder.py : http://pastebin.com/1S9PR5mu, 추적 오류 : http://pastebin.com/siNGzMvx 그래서 그냥 움직임을 통해. 최소한 gstreamer는 어떻게 보이나요? –
