hello,   i've added fullscreen features to the xvimagesink plugin, which allows the plugin to go into fullscreen mode. basically ive written a function that achieves this, but there seems to be a problem sometimes while going into the fullscreen mode, [problems] sometimes while switching to the fullscreen mode, the window just dissapears and fullscreen never appears. and sometimes XIO:  fatal IO error 0 (Success) on X server ":0.0"       after 197 requests (195 known processed) with 0 events remaining. [end] maybe im not aquiring the correct locks, or the fullscreen_toggle() is not done at the proper location in code. currently im aquiring a lock on the flow and to the xcontext, i.e. g_mutex_lock(xvimagesink->flow_lock)  and g_mutex_lock(xvimagesink->x_lock) .. Probably i should be able to fix this with the help of Julien Moutte (original code author). Code Additions ive made: 1] gst_xvimagesink_toggle_fullscreen(), toggles the fullscreen mode. 2] Installed fullscreen property on the plugin (so that the pipeline can start in fullscreen mode) 3] Installed title property on the plugin (so u can set the title of the xv window to something u like, default "XVImageSink") 4] Capturing X Keypress Events for keys F and f to toggle fullscreen and Key Escape to switch to window mode when in fullscreen. i would like to know where i should submit the code additions ive made. and would also like to know whether i need to describe what im doing in the code additions. regards snaik
