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. |

General Idea:
=============
_____/ gstv4lsrc.[ch]
_____/ \ v4lsrc_calls.[ch]
/
gstv4lelement.[ch] _/____________/ gstv4lmjpegsrc.[ch]
v4l_calls.[ch] \ \ v4lmjpegsrc_calls.[ch]
\_____
\_____/ gstv4lmjpegsink.[ch]
\ v4lmjpegsink_calls.[ch]
I.e., all the files on the right are child classes of
the v4lelement 'parent' on the left.
* v4lelement handles generic v4l stuff (picture settings,
audio, norm/input setting, open()/close())
* v4lsrc, v4lmjpegsrc handle the capture specific
functions. Maybe we'd need a v4lmpegsrc too
* v4lmjpegsink handles mjpeg hardware playback of video
