OSError：[errno2]没有这样的文件或目录，并且OSError：[Errno 12]无法分配内存

Question

我正在尝试使用Apache Kafka和FFmpeg转换视频。我已经在系统上运行了程序，但是在服务器上运行时失败。我运行代码时遇到此错误：

Traceback (most recent call last):
  File "/home/fu/kafka/kafkaVideo/ffmpeg-python-master/ffmpeg/send.py", line 30, in <module>
    subprocess.call([sys.executable, start])

    return Popen(*popenargs, **kwargs).wait()
