+ * docs/random/mimetypes:
+ update docs for audio/x-raw-float. Add "buffer-frames=0 means
+ undefined"
+ * gst/elements/gstfilesrc.c: (gst_filesrc_set_location):
+ make it only work in NULL.
+ * gst/gstcaps.c:
+ don't posion NULL caps
+ * gst/gstelement.c: (gst_element_set_time):
+ add debugging statement
+ * gst/gstelement.c: (gst_element_emit_found_tag),
+ (gst_element_found_tag_func), (gst_element_found_tags):
+ * gst/gstelement.h:
+ These functions take const taglists
+ * gst/gstpad.c: (gst_pad_proxy_getcaps):
+ fix memleak
+ * gst/gstpad.c: (gst_pad_event_default):
+ make more effort on handling discont and clocks, g_warn if everything
+ fails
+ * gst/gststructure.c: (gst_structure_remove_fields),
+ (gst_structure_remove_fields_valist):
+ * gst/gststructure.h:
+ add gst_structure_remove_fields(_valist)
+ * gst/gsttag.c:
+ fix doc glitch

2 - Raw Audio (floating point format)
mimetype: audio/x-raw-float
- properties: 'depth' = X (INT) <- 32=float, 64=double
+ properties: 'width' = X (INT) <- 32=float, 64=double
'endianness' = 1234/4321 (INT) <- use G_BIG/LITTLE_ENDIAN!
'buffer-frames' = (INT)
+ number of samples per buffer, 0 means undefined
With regards to the signal: 0.0 represents no signal, +/- 1.0 is 0 dB.
