RecordMyDesktop steps

I found this page Activity Screencast! Must research and test!

  1. Get Sugar installed and internet connection working
  2. Go to terminal (can be found in list of activities)
  3. Go to root by typing
 su

You are looking for RecordMyDesktop. Read the very old help pages. They'll give you some clues to the operation of RecordMyDesktop(RMD) though I must say that after playing with RMD on Sugar I much prefer RMD on Ubuntu.

  1. Type:
yum install recordmydesktop

RecordMyDesktop is command line only. Use GTK below for the GUI. 

yum install gtk-recordmydesktop

or this one written in Python WHICH should be more stable on Sugar as Sugar is written in Python... though amazingly qt-recordmydesktop asked for 27M of space where gtk-recordmydesktop only asked for a few 100K! Bemasc at the IRC rightly pointed out that QT is a big app and that there are huge buffering considerations for using RMD in general. 

yum install qt-recordMyDesktop

GStreamer

Bemasc found this. Test it on the command line. Let us know. 

gst-launch ximagesrc ! video/x-raw-rgb,framerate=5/1 ! ffmpegcolorspace ! theoraenc ! oggmux ! filesink location=desktop.ogg

Why make screencasts?

Video, when done properly, can explain a lot more than text. And video can overcome some of the language barriers by SHOWING people what to do and their expected outcomes.

Possible errors you may encounter with RecordMyDesktop

[root@localhost liveuser]# gtk-recordMyDesktop /usr/lib/python2.6/site-packages/recordMyDesktop/rmdMonitor.py:10: DeprecationWarning: The popen2 module is deprecated. Use the subprocess module. import popen2 /usr/lib/python2.6/site-packages/recordMyDesktop/rmdSimple.py:223: DeprecationWarning: os.popen3 is deprecated. Use the subprocess module. (stdin,stdout,stderr)=os.popen3(xwininfo_com,'t') The program 'gtk-recordMyDesktop' received an X Window System error. This probably reflects a bug in the program. The error was 'BadAlloc (insufficient resources for operation)'. (Details: serial 3927 error_code 11 request_code 53 minor_code 0) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.)

  • No known workaround for this yet.
