gst/base/gstbasetransform.c: use gboolean return values and pointers to size so we can use the full GST_BUFFER_SIZE r...
Original commit message from CVS: * gst/base/gstbasetransform.c: (gst_base_transform_transform_caps), (gst_base_transform_transform_size), (gst_base_transform_getcaps), (gst_base_transform_setcaps), (gst_base_transform_get_unit_size), (gst_base_transform_buffer_alloc), (gst_base_transform_handle_buffer): use gboolean return values and pointers to size so we can use the full GST_BUFFER_SIZE range (guint) for buffer sizes use GstPadDirection for transform_caps * gst/base/gstbasetransform.h: rename get_size to get_unit_size since that's what it is * gst/elements/gstcapsfilter.c: (gst_capsfilter_transform_caps): use GstPadDirection for transform_caps * gst/gstbuffer.c: (gst_buffer_new_and_alloc): * gst/gstutils.h: cleanup and debugging
