RecordMyDesktop steps
I found this page Activity Screencast! Must research and test!
- Get Sugar installed and internet connection working
- Go to terminal (can be found in list of activities)
- 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.
- 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.
