@ -3,11 +3,13 @@ TODO list (short term):
* as soon as we've trashed Gtk-1.2, change 'gint palette'
to 'guint16 palette' in gstv4lsrc.[ch]
* v4lsrc: actually try the format out on capsnego
* all plugins: on try_set_caps(), loop try_set_caps() per caps
instead of using a multi-caps so we know the end-format
* all three: fix interlacing (not handled at all...)
* add overlay handling in v4lelement
* libgstrec
* avidemux: add events (seek)
* avimux: fps calculations
* avimux: fps calculations (or make that a set/get_property()?)
