'--output-res 720x304',

that seems wrong,...

but because I commented "ctypes.memmove" so that the pipe is not used.

so it is not working at all,...

1) the buffersize should be increased to allow the encoder to encode at least some seconds of movie

What buffer size? There is no buffer in this at all,.. ah, you mean from popen (that should change the result)
