Xvidcap exits with "BadMatch" error

[jdb2]

Binary package hint: xvidcap

When trying to record video from a Firefox window which contains an embedded flash video Xvidcap fails after the "Start recording" button is clicked with this error :

"
The program 'xvidcap' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 1808 error_code 8 request_code 139 minor_code 4)
  (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.)
"

I've tried the latest version of Opera so this is not a Firefox specific issue.

The error can be reproduced on this page :

I forgot to mention the command I used :

xvidcap --fps 30000/1001 --audio yes --window 0x6000065 -v --file duke.avi

I've verified that gtk-recordmydesktop works on the above mentioned web page.

I can confirm that this bug is still present in the latest release of Lucid ( Linux aleph1 2.6.38-8-generic #42~lucid1-Ubuntu SMP Mon Apr 11 13:45:06 UTC 2011 x86_64 GNU/Linux ).

Trying to capture video from a Firefox 4.0.1 window -- just a Gmail session in this case -- results in an error similar to the above after pressing the "record" button :

jdb2@aleph1 ~/screencap $ xvidcap --fps 30000/1001 --sf --auto --file cap%0.9.ppm --gui yes --window 0x580006c

Debugging output is attached.

Looks like in this particular case, unlike the previous one involving the embedded video, xvidcap is crashing because I did not select an area to be captured.

Here's more extensive debugging information for what it's worth. Note that I've compiled xvidcap from the source package and run GDB against it.

Comment #6 has the wrong text file attached. Here is the correct one.
