Yes, I install all packages including gst*.

I would prefer python about pygst, but any other language is ok. If I just use package from cygwin mirrors, I will get the following error. I rebased many times,it does not work. 0 [unknown (0x2F04)] python2.7 2144 child_copy: loaded dll data write copy failed, 0x36402000..0x36402044, done 0, windows pid 5768, Win32 error 487 The pulseaudio.exe is always running even when I close the Cygwin/X and Cygwin.(I can use ps and kill -9 pid or just use windows Task Manager to shutdown it). Every time I start Cygwin and run a pygst, a new pulseaudio is spawned. After several times, there will be many pulseaudio.exe in windows background. It plays mp4 well, because I install gstreamer0.10-plugins-ffmpeg from cygwinports.org. The package from cygwin mirrors cannot do that. I am willing to try something to solve this problem. I would be glad to make contribution to pulseaudio package if possible. Any suggestion would be appreciated.
