GST_VIDEO_CAPS_xxx -> GST_VIDEO_CAPS_MAKE(xxx)
|
||||
|
||||
Some caps functions now take ownership of the input argument, for
|
||||
efficiency reasons (to avoid unnecessary copies to make them writable):
|
||||
|
||||
gst_caps_normalize (caps) => caps = gst_caps_normalize (caps)
|
||||
gst_caps_do_simplify (caps) => caps = gst_caps_simplify (caps)
|
||||
gst_caps_merge (caps,caps2) => caps = gst_caps_merge (caps,caps2)
|
||||
gst_caps_merge_structure (caps,st) => caps = gst_caps_merge_structure (caps,st)
|
||||
gst_caps_truncate (caps) => caps = gst_caps_truncate (caps)
|
||||
|
||||
The compiler should warn about unused return values from these functions,
|
||||
which may help find the places that need to be updated.

abs_rate was removed from the public fields, it can be trivially calculated
|
||||
from the rate field.
