Internally BPMDetect assumes that at most 2048 samples are passed
to it at once and stores those in a stack allocated static sized
array. If we pass too many samples this will result in a buffer overflow
resulting in heavy stack corruption and a crash. Fixes bug #570996.
Original commit message from CVS:
* ext/mpeg2enc/gstmpeg2enc.cc:
* ext/soundtouch/gstbpmdetect.cc:
Cast NULL sentinels to void * as NULL is defined as an integer
constant in most environments when using C++ and it's size might
be different from a pointer.
Original commit message from CVS:
* configure.ac:
* ext/mpeg2enc/Makefile.am:
* ext/soundtouch/Makefile.am:
* gst/modplug/Makefile.am:
Check for and define ERROR_CXXFLAGS and GST_CXXFLAGS and use them
when building C++ code.
Original commit message from CVS:
* ext/soundtouch/gstbpmdetect.cc:
Clean up a bit and only allocate a temporary buffer for the data
if processing stereo data as BPMDetect downmixes from stereo to
mono and stores the result in the input data. Thanks to
Stefan Kost for the suggestions.
Original commit message from CVS:
* ext/soundtouch/gstpitch.cc:
* ext/soundtouch/gstpitch.hh:
Implement LATENCY query and notify about latency changes.
Unfortunately we don't have a fixed latency but it changes
a bit with each buffer so we only send an LATENCY event with
the maximum latency if it changes.
Always calculate the timestamp, duration, etc from the sample
rate instead of using a pre-calculated duration for one sample
to prevent large rounding errors.

* ext/soundtouch/Makefile.am:
* ext/soundtouch/gstbpmdetect.cc:
* ext/soundtouch/gstbpmdetect.hh:
* ext/soundtouch/plugin.c: (plugin_init):
Add BPM detection plugin based on SoundTouch's libBPM.
* ext/soundtouch/gstpitch.cc:
Allow sample rates until MAX instead of only 48kHz and remove the
buffer-frames field from that caps.
Clear the remaining samples completely when necessary to get into
a clean state again.
Original commit message from CVS:
* ext/soundtouch/gstpitch.cc:
Allow seeking only in TIME and DEFAULT format, other formats will
not work as expected. Also handle a stop position of -1 correctly
for seeks, newsegment events and the queries. This fixes playback
with the pitch element if upstream doesn't know the duration or has
-1 as stop position in NEWSEGMENT events for other reasons. Before
simply nothing was played as the segment was going from 0 to 0.
Send a GST_MESSAGE_DURATION whenever the rate or tempo is changed
so applications can update their cached duration. Fixes bug #503308.
Some random cleanup and memory leak closing.
Original commit message from CVS:
* configure.ac:
* ext/soundtouch/gstpitch.cc:
Add support for libsoundtouch 1.3.1 and add an ugly workaround for
the header definined PACKAGE and other variables for which we need
our own values from config.h.
Original commit message from CVS:
* configure.ac:
Require core CVS. This is implicit in the -base CVS
requirement already, so we might just well spell it
out. Also, we do need at least 0.10.14 for
gst_element_class_set_details_simple(). Make check
for gmyth a bit more restrictive so things don't break
if the next version changes API.
* ext/alsaspdif/alsaspdifsink.c:
Work around alsa alloca macros triggering 'always evaluates to
true' warnings with gcc-4.2 and fix compilation with gcc-4.2.
Also don't leak the device string.
* ext/mpeg2enc/gstmpeg2enc.cc:
* ext/soundtouch/gstpitch.cc:
* gst/modplug/gstmodplug.cc:
Fix compilation with g++4.2 and -Wall -Werror (also needs plugin
define fix from core CVS). Fixes#462737.
Original commit message from CVS:
* ext/soundtouch/gstpitch.cc:
If we receive a new segment event, don't try to push buffers out
in response (without first sending it on!).
Instead, flush internal buffers on receiving flush events.
Fixes playback after seeking.
Original commit message from CVS:
Patch by: Wouter Paesen <wouter at kangaroot net>
* ext/soundtouch/Makefile.am:
* ext/soundtouch/gstpitch.cc:
Make pitch element controllable via GstController interface
(#344821).
* configure.ac:
Up core requirements to 0.10.8.1/CVS because earlier
GstControllers can't handle float properties correctly.
Check for GstController CFLAGS and LIBS.
* tests/icles/Makefile.am:
* tests/icles/pitch-test.c: (main):
Add small test program for the above (welcome to the 80s!).
