Subject: gst/gstbuffer.c: Small docs update.
X-Git-Tag: RELEASE-0_10_1~54
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d16ce65df7fa236b106ab6fa5f3bf37f23d1c921;p=platform%2Fupstream%2Fgstreamer.git

gst/gstbuffer.c: Small docs update.

Original commit message from CVS:
* gst/gstbuffer.c:
Small docs update.

* gst/gstcaps.c: (gst_caps_is_equal):
Don't assert on NULL <--> X. Fixes #323260

* gst/gstminiobject.c: (gst_mini_object_replace):
If we're doing atomic operations, we might just as well use
the proper way to get an atomic pointer.

* libs/gst/base/gstbasesink.c: (gst_base_sink_get_position):
Clean up debugging.
