Original commit message from CVS: * configure.ac: * ext/Makefile.am: Fixes to make ext/libcaca compile. * ext/divx/gstdivxdec.c: * ext/gdk_pixbuf/gstgdkpixbuf.c: (gst_gdk_pixbuf_sink_link), (gst_gdk_pixbuf_init), (gst_gdk_pixbuf_chain): Make gdkpixbufdec handle images that span multiple buffers. Now work with both filesrc ! gdkpixbufdec and qtdemux ! gdkpixbufdec. * ext/gdk_pixbuf/gstgdkpixbuf.h: * ext/libcaca/gstcacasink.h: Fixes needed due to recent video/video.h changes * ext/xvid/gstxvid.c: (gst_xvid_csp_to_caps): same * sys/v4l/gstv4lmjpegsrc.c: (gst_v4lmjpegsrc_get), (gst_v4lmjpegsrc_buffer_free): Use buffer free function instead of GstData free function. * sys/v4l/gstv4lsrc.c: (gst_v4lsrc_get), (gst_v4lsrc_buffer_free): same.
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
