We got Keith to *start* fixing it the other day. I don't see that a fix has been 
committed yet. I think he was too distracted by the rest of the rocket meeting to 
finish the work.

Darn it, what good is a rocket meeting if you can't get any decent X hacking done?!

>> Hi all,
>> Finally I managed to create xcb versions of the xshm and the xv output 
>> patch_one.diff contains the necessary changes to include/xine.h.
>> patch_two.diff adds all the needed autotools changes.
>> patch_three.diff removes some unused variables in the current xshm plugin.
>> video_out_xcbshm.c, video_out_xcbxv.c, xcbosd.c, xcbosd.h all belong
>> to src/video_out.
>> kaffeine_patch.diff is a kaffeine hack for testing all this.
>> Some notes:
>> * The required version of libxcb is 1.0 (0.9.93 may also work, but I

>> * You still need a mutex in the output plugins; not because of the xcb

>> * There's an issue with large images when not using shared memory [1].

>> * This message was sent to the xine-devel list with the attachments.
>> Thanks to different people who made this possible ;)
>> * Vincent Torri for giving me xcb support whenever i needed it.
>> * Jamey Sharp for caring about the large image issue.
>> * Christophe Thommeret for providing the autotools patch and testing
