Most signal processing texts, including MATLAB, use the following convention for IIR filter coefficients:
a_0 y[n] + a_1 y[n-1] + ... + a_M y[n-M] = b_0 x[n] + b_1 x[n-1] + ... + b[N] x[n-N]
Usually, a_0 is set to 1 because the coefficients can always be rescaled, giving
y[n] = b_0 x[n] + b_1 x[n-1] + ... + b[N] x[n-N] - a_1 y[n-1] - ... - a_M y[n-M]
The convention that was previously used by audiofxbaseiirfilter and derived class had the a and b coefficients swapped, and did not have the minus signs.
This change makes the audiofx plugin use the more common convention described above.
wavenc only accepts little-endian PCM, but most of our
elements such as audiotestsrc only produce or process
audio in native endianness, so we need to plug a
converter before wavenc on big endian systems.
Some tests assumed that tag events would always pushed through
immediately, which isn't the case any longer, so push a newsegment
event and an empty buffer first.
Support for TAG_IMAGE and TAG_ATTACHMENT is commented out; this requires caps
on buffers which is gone from 0.11.
Segment handling in the demuxer is a bit complex; I added some FIXME comments
in places where I'm not yet sure if I ported correctly.

Some possible FIXMEs remaining in the audio parser getcaps functions.
Tests fail to build because g_mkdtemp is available from glib since
2.26.
This patch adds a condition around the redefinition of
g_mkdtemp on the tests to only build it if glib is older than
2.26.
When pushing out buffers over S/PDIF or HDMI, IEC 61937 payloading
requires each buffer to contain 6 blocks from each substream. This adds
code to collect all the frames needed to meet this requirement before
pushing out a buffer.

This is needed for automatic transcoding using encodebin. Our typefinder
does not always add a variant to the found caps, and encodebin needs
an *exact* match to the caps on the source pad template, so we need
to add the variant-less video/quicktime caps to the template as well
for encodebin to be able to find it. Add unit test for this as well.
https://bugzilla.gnome.org/show_bug.cgi?id=642879
Makes some improvements to tagschecking.c, making it use
fakesrc instead of videotestsrc and allowing to set input
caps so that more muxers can be used. Previously we could
only use those that accepted raw video caps.
Also adds some tests for geo-location tags
Adds a check unit test that aims to test tags serialization
and deserialization consistency (in muxers). It provides a
basic function that allows one to easily specify tags, a
muxer and a demuxer and a test will be done to check if
the tags have been consistently muxed and demuxed

Garbage after frames is now included in the frames because flacparse
has no easy way to detect the real end of a frame. Decoders are
expected to everything after the frame because only decoding the
bitstream will reveal the real end of the frame.
Fixes bug #631814.
It's an external which lives in gstcheck.c. Redeclaring it makes some
compilers/architectures think the 'buffers' in the individual tests are
a different symbol... and therefore we end up comparing holodecks with
oranges.
Create output caps from input caps, so we maintain any fields we
might get on the input caps, such as codec_data or rate and channels.
Set channels and rate on the output caps if we don't have input caps
or they don't contain such fields. We do this partly because we can,
but also because some muxers need this information. Tagreadbin will
also be happy about this.
Original commit message from CVS:

Add unit tests for new parsers.
Jack audio src/sink elements recently got moved from bad and should be excluded
from the test (like the other device specific source and sinks).
Fixes#644288
Images might have framerate=0/1 in the caps, which caused an
assertion on deinterlace. I don't know of interlaced image formats
but deinterlace might be hardcoded on some generic pipelines and
it shouldn't assert.
The fix was to set field_duration to 0 if the input has a framerate
with a 0 numerator.
This patch also adds checks for this situation on the unit tests.
https://bugzilla.gnome.org/show_bug.cgi?id=641400
The unit tests are riddled with g_assert() and friends, make sure we
don't disable assert and cast checks for the unit tests even if
this has been specified for the rest of the code base, e.g. via
--disable-glib-asserts.
First bring down everything to NULL before attempting to unlink
or unref anything.
Avoids the tests just hanging there for ever waiting to acquire a
lock that doesn't exist anymore.
If setting the pipeline to PLAYING before issuing the seek, buffers
are already arriving at the sink before the seek is handled and
will have the wrong timestamps and everything.
Fixes bug #625547.
So matroska's Block structure has no keyframe flag, only the SimpleBlock has it.
To detect keyframes in Blocks, it is just the BlockGroup container that needs
to have a ReferenceBlock attached if it is a delta frame in video.
deinterlace now always adds the interlaced field to the output caps,
if it wasn't present in the input caps the output caps will still
contain interlaced=false.
It's an external which lives in gstcheck.c. Redeclaring it makes some
compilers/architectures think the 'buffers' in the individual tests are
a different symbol... and therefore we end up comparing holodecks with
oranges.
This just replaces every "$ERROR_CFLAGS" usage with a usage of
"$WARNING_CFLAGS $ERROR_CFLAGS" to get the same functionality as
previously.
Actually using that separation will happen later.
Now the alpha is multiplied with the already existing alpha
value instead of simply ignoring it and the luma/chroma values
are kept, even if the output is 100% transparent.
Make sure we set a base_time on the element.
Fix the timeout to at least twice the jitterbuffer latency.
Enable previously failing tests.
Remove impossible checks.
CHange the backwards test to always send first buffer first to have a define
basetime. Add another test that sends buffers backwards to assert that only
first sent buffer is keep and used as basetime. Disabled those tests still,
as its not passing/failing consitently and file a bug for jitterbuffer.
The souphttpsrc test wasn't compiling. The soup-misc.h header is needed for
soup_ssl_supported.
Fix the y4menc test to use a 'progressive' header for the test data now that
the element outputs correct interlacing info.
Connect to the pad-removed signal of the ptdemux elements so that we remove the
ghostpads for them. Fixes cleanup when going to NULL as well as when releasing
the sinkpads.
Fixes#561752
flvmux only accepts raw audio in little endian, but audiotestsrc
produces audio in the native endianness, which makes linking
between audiotestsrc and flvmux fail on big endian machines. Add
an audioconvert element in between the two to fix this.
Reversing the unsynchronisation seems to work slightly differently
for ID3 v2.3 tags and v2.4 tags: v2.3 tags don't have syncsafe frame
sizes in the frame header, so the unsynchronisation is applied to
the whole frame data including all the frame headers. v2.4 frames
have sync-safe sizes, however, so the unsynchronisation only needs
to be applied to the actual frame data, and it seems that's what's
being done as well. So we need to undo the unsynchronisation on a
per-frame basis for v2.4 tags for things to work properly.
Fixes extraction of coverart/images from APIC frames in ID3 v2.4
tags (#588148).
Add unit test for this as well.
Request pads are removed by the element instance in PAUSED->READY
so we need to re-request pads for every run and link them again.
Last fix for bug #590447.
Changing directory invalidates the paths the registry has picked
up for our plugins, because the test environment specifies relative
paths. Fixing that is a separate problem, in the meantime, build a
path to the test files instead of changing directory. Fixes the
distcheck.
Move unit test data into the directory where it belongs and make in particular
the flacdec unit test cd into the directory with the test files instead of making
assumptions about the current working directory in that unit test. As a side effect
of movng those files, there's only one EXTRA_DIST in tests/check/Makefile.am now,
which is likely to work better than having two. Hopefully fixes#582753.
Flacdec outputs 16-bit samples, so let's check if the value of the first
sample is what we expect rather than just the first byte, which may be
different from what we expect depending on the host's endianness. Fixes
the flacdec unit tests on PPC. Also fix a bunch of leaks in the unit
tests to make valgrind happy. Fixes#582420.
The test creates buffers with non-silence, sets the GAP
flag on it and expects rganalysis to ignore the content and assume silence.
That's not the way how GAP buffers should be used, if the GAP flag is set
elements *can* assume that they only contain silence but they're not *required*
to assume that. The GAP flag must only be set on silence buffers.
Fixes bug #582252.
from a 10-buffer audiotestsrc flac, in the case of:
- a full decode
- a decode of a seek for the full file
- a decode of a seek for a small part, smaller than the first buffer
The test fails because flacdec drops the first outgoing buffer on a seek
Cast the new value for the "delay" property to GstClockTime.
Integers without type are passed to vararg functions with
an integer type that can hold a pointer.
A recent commit added video/x-raw-gray support to videocrop. However
this lets the videocrop unit test fail. Because videotestsrc can't
generate this format.
The element can add an echo and a simple reverb effect to
an audio stream but for a real reverb filter it would need
some additional filtering to prevent a metallic-sounding
result.
