We now keep the fft data that is related to one channel in a separate structure
to prepare for multichannel support. We also refactor the code to operate more
often on the channel context.
Use 'input' instead of 'spectrum->input' which was intende already (variable
exists, but not used everywhere). Also use a local version of
'spectrum->input_pos'.
consistently only update if the property actualy changed the value. Do it
without reading the gvalue twice. No need to reset the spectrum analyzer for
threshold changes.
Link to properties. Correct titles for examples. Document a few trivial cases. Keep lists in section file and docs/plugins/Makefile.am alphabetically ordered.
Original commit message from CVS:
* gst/spectrum/gstspectrum.c: (gst_spectrum_reset_state),
(gst_spectrum_transform_ip):
* gst/spectrum/gstspectrum.h:
Implement a simple compensation algorithm for rounding errors.
This makes sure that a spectrum message is posted on the bus
every interval nanoseconds. Fixes bug #567955.
Original commit message from CVS:
* gst/spectrum/gstspectrum.c: (gst_spectrum_reset_state):
Don't call gst_fft_f32_free() with NULL to prevent a
crash. Fixes bug #567642.
Original commit message from CVS:
* gst/spectrum/gstspectrum.c: (gst_spectrum_transform_ip):
* gst/spectrum/gstspectrum.h:
Use correct types for frame/fft counters and some minor
cleanup.

if the interval is small than the length of the FFT.
Fixes bug #567642.
Major cleanup of the spectrum element.
Original commit message from CVS:
* gst/level/gstlevel.c:
Little renaming (l -> level).
* gst/spectrum/gstspectrum.c:
* gst/spectrum/gstspectrum.h:
Also send full timestamp/duration details here.

* gst/spectrum/gstspectrum.c: (gst_spectrum_class_init),
(gst_spectrum_init), (gst_spectrum_set_property),
(gst_spectrum_get_property), (gst_spectrum_message_new):
Rename property enums and default defines for the properties to match
the property names and rephrase property descriptions to make them a
bit clearer (hopefully). See #518188.

Add a simple example application for the spectrum element, include it
in the docs, and fix some documentation ambiguities.
Fixes: #348085
Original commit message from CVS:

Change the meaning of the magnitude values given in the
GstMessages by spectrum to decibel instead of
decibel+threshold.
Original commit message from CVS:
* gst/spectrum/gstspectrum.c:
Now do the scaling right for real. Also initialize a previously
uninitialized variable.
Original commit message from CVS:
* gst/spectrum/demo-audiotest.c: (main):
Use autoaudiosink instead of alsasink and use a sine wave.
* gst/spectrum/gstspectrum.c:
Fix the magnitude calculation.
Original commit message from CVS:
* ChangeLog:
Add missing newline.
* gst/librfb/rfbdecoder.c:
Fix the build (missing stdlib.h).
* gst/spectrum/gstspectrum.c:
* gst/spectrum/gstspectrum.h:
Use basetransform segment so that it is correctly managed on flushes
and start/stop. Report message timestamp as stream time, which is what
an application can understand. (Yes these are adapted from wim recent
level element changes)
Original commit message from CVS:
* gst/spectrum/gstspectrum.c: (gst_spectrum_start),

average all FFTs done in one interval for better results, use
a better windowing function, allow posting the phase in the message
and actually do an FFT with the requested number of bands instead
of interpolating.
