Buffers should have readlocks and writelocks to enforce
|
|
GST_BUFFER_DONTKEEP and relax the restriction that buffers with
|
|
multiple refcounts are read-only.
|
|
|
|
|
|
|
|
Example:
|
|
|
|
videotestsrc ! ximagesink
|
|
|
|
videotestsrc requests a buffer from its src pad
|
|
|
|
ximagesink creates a buffer (refcount:1 readlock:0 writelock:0)
|
|
|
|
videotestsrc writelocks it (refcount:1 readlock:0 writelock:1)
|
|
|
|
videotestsrc writes to the buffer
|
|
|
|
videotestsrc un-writelocks it (refcount:1 readlock:0 writelock:0)
|
|
|
|
ximagesink readlocks it (refcount:1 readlock:1 writelock:0)
|
|
|
|
ximagesink writes it to the screen
|
|
|
|
ximagesink un-readlocks it (refcount:1 readlock:0 writelock:0)
