View file

@ -5,6 +5,13 @@ TODO list (short term):
* v4lsrc: actually try the format out on capsnego
* all three: fix interlacing (not handled at all...)
* libgstrec: build (a library for video recording)
For other plugins:
* SDL: seems okay for now
* jpegmmxenc/dec: seems okay for now
* avidemux: seems okay for now, though it doesn't really handle
events yet
* avimux: interaction with disksink, maxfilesize support, events
(GST_EVENT_RESTART!!->s/RESTART/NEW_MEDIA/), etc. - big TODO
TODO list (long term):
