Original commit message from CVS:
* gst/playback/gstdecodebin.c: (close_pad_link):
Fix typo in a debug statement.
* gst/playback/gstplaybasebin.c: (probe_triggered),
(new_decoded_pad_full), (new_decoded_pad), (subs_new_decoded_pad),
(gen_source_element), (source_new_pad), (analyse_source),
(setup_source):
When handling no_more_pads in new_decoded_pad, make sure to treat
subtitle pads correctly. Fixes playback with subtitle files.
Move a recurring message to LOG level.
* sys/xvimage/xvimagesink.c: (gst_xvimagesink_get_xv_support):
The maximum value for the Xv colorkey on this Radeon is 0xFFFFFFFF,
which ends up as -1 when cast to an int. Make the logic handle the
max value as an unsigned mask and only change the colorkey when it's
a value we recognise.
