Thanx for trying Stewart, but that is not what I need The output of mencoder is not readable with readlines (i tried it) because after the initial informational lines You don't get lines anymore (you get a linefeed but no newline) The prints are all on the same line (like a status line) something like Pos: 3,1s 96f ( 0%) 42fps Trem: 0min 0mb A-V:0,038 [171:63] which is coninually updated while the process runs... > in your app, you could create a Tkinter stringVar, say myOutput, for > the process output.

I really like to know how I can catch the output of a subproces.Popen() command and redirect it to something else (like a textwidget ) and I really like to use the subprocess module (standard in v2.4) to get to know it. Another reason to use the subprocess module is I can stop the process because I know the handle of the thread. The subprocess module knows all this. cheerz, Ivo. -- http://mail.python.org/mailman/listinfo/python-list
