This is strange.
Is this the error you get? FYI: gr-video-sdl is not installed realtime SDL video output window will not be available And you don't get this error when you run test_video-sdl.py (I put the code of test_video-sdl.py at the end of this mail) Both usrp_tv_rcv.py and test_video-sdl.py use exactly the same code to check for the availability of video_sdl. This is done in these lines: try: from gnuradio import video_sdl except: print "FYI: gr-video-sdl is not installed" print "realtime SDL video output window will not be available" So or both should output nothing, or both should work. Can you check if video_sdl.py is actually installed and where it is installed. Mine is located at: /usr/local/lib/python2.3/site-packages/gnuradio/video_sdl.py You can use the following to find all instances of video_sdl.py locate video_sdl.py or if locate isn't installed/configured cd / find -name video_sdl.py Greetings, Martin #!/usr/bin/env python # # Copyright 2006 Free Software Foundation, Inc. # # This file is part of GNU Radio # # GNU Radio is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2, or (at your option) # any later version. # # GNU Radio is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
