Original commit message from CVS: * sys/v4l/Makefile.am: * sys/v4l/gstv4l.c: (plugin_init): * sys/v4l/gstv4lelement.c: (gst_v4lelement_get_type), (gst_v4lelement_init), (gst_v4lelement_dispose), (gst_v4lelement_change_state): * sys/v4l/gstv4lelement.h: * sys/v4l/gstv4lxoverlay.c: (gst_v4l_xoverlay_open), (gst_v4l_xoverlay_close), (idle_refresh), (gst_v4l_xoverlay_set_xwindow_id): * sys/v4l/gstv4lxoverlay.h: * sys/v4l/v4l-overlay_calls.c: * sys/v4l/v4l_calls.h: * sys/v4l2/Makefile.am: * sys/v4l2/gstv4l2.c: (plugin_init): * sys/v4l2/gstv4l2element.c: (gst_v4l2element_get_type), (gst_v4l2element_init), (gst_v4l2element_dispose), (gst_v4l2element_change_state): * sys/v4l2/gstv4l2element.h: * sys/v4l2/gstv4l2xoverlay.c: (gst_v4l2_xoverlay_open), (gst_v4l2_xoverlay_close), (idle_refresh), (gst_v4l2_xoverlay_set_xwindow_id): * sys/v4l2/gstv4l2xoverlay.h: * sys/v4l2/v4l2-overlay_calls.c: * sys/v4l2/v4l2_calls.h: Remove client-side overlay handling, use the X-server v4l plugin for that. Nicer overlay, less code. Also make the plugin compileable without X (but then without overlay, obviously). Makes xwindowlistener obsolete, should we remove that?

/* Because of some really cool feature in video4linux1, also known as
|
|
* 'not including sys/types.h and sys/time.h', we had to include it
|
|
* ourselves. In all their intelligence, these people decided to fix
|
|
* this in the next version (video4linux2) in such a cool way that it
|
|
* breaks all compilations of old stuff...
|
|
* The real problem is actually that linux/time.h doesn't use proper
|
|
* macro checks before defining types like struct timeval. The proper
|
|
* fix here is to either fuck the kernel header (which is what we do
|
|
* by defining _LINUX_TIME_H, an innocent little hack) or by fixing it
|
|
* upstream, which I'll consider doing later on. If you get compiler
|
|
* errors here, check your linux/time.h && sys/time.h header setup.
