Original commit message from CVS: 2005-07-07 Andy Wingo <wingo@pobox.com> * sys/v4l/v4lsrc_calls.h: * sys/v4l/v4lsrc_calls.c: Remove sync-related stuff. (gst_v4lsrc_get_fps_list): Moved here from gstv4lsrc.c. (gst_v4lsrc_buffer_new): Totally derive from GstBuffer. * sys/v4l/v4l_calls.h: Cast to V4lElement. * sys/v4l/v4l_calls.c: Header loc fixen, don't load mjpeg, all v4lelements are sources. * sys/v4l/gstv4lxoverlay.h: * sys/v4l/gstv4lxoverlay.c: * sys/v4l/gstv4ltuner.h: * sys/v4l/gstv4ltuner.c: Header loc fixen. * sys/v4l/gstv4lsrc.h: * sys/v4l/gstv4lsrc.c: Crucial GPL update. Clean up a bit, port to PushSrc/BaseSrc. Removed most sync-related properties, videorate or something should handle that. Made a live source. * sys/v4l/gstv4lelement.h: * sys/v4l/gstv4lelement.c: Derive from GstPushSrc. No more signals. Some cleanups. * sys/v4l/gstv4lcolorbalance.h: Interface header update. * sys/v4l/gstv4l.c: Don't register v4lelement, or the jpeg/mjpeg stuff. * sys/v4l/Makefile.am: Build everything except the jpeg/mjpeg stuff. * sys/Makefile.am (SUBDIRS): Hit the V4L crack pipe.

/* 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.
