Also fixes the condition for the 2ch case to be exact, rather than at
least 2 channels since the downmix will not take place in the >stereo
case.

We need to initialize the AudioUnit early to be able to probe the

AudioUnitUninitialize() documentation, format changes should be done
while the AudioUnit is uninitialized. So we explicitly uninitialize the
AudioUnit during a format change and reinitialize it when we're done.

f107f7306b osxaudio: Fix lockup in _audio_unit_property_listener
_audio_unit_property_listener is called either from a Core Audio thread
or as a result of a Core Audio API (e.g. AudioUnitInitialize)
from our own thread. In the latter case, osxbuf can be already locked
(GStreamer's mutex is not recursive).

We introduce the flag cached_caps_valid and use it instead of nullifying
cached_caps when we cannot lock on osxbuf.

As it's very common, handle driver not setting field in buffers
by using the field value from the format. This workaround a long time
bug in UVC driver. For even buggier driver, we simply assume
progressive as before. We also only warn once, to avoid spamming.

88703ae585 v4l2: query crop configuration after each call of S_CROP
S_CROP ioctl is write-only and the device can adjust crop rectangle so
we query back the crop configuration after each S_CROP to know what has
been done.

600027a1ee v4l2bufferpool: fix import_userptr() in single-planar API when n_planes > 1
In the V4L2 single-planar API, when format is semi-planar/planar,
drivers expect the planes to be contiguous in memory.
So this commit change the way we handle semi-planar/planar format
(n_planes > 1) when we use the single-planar API (group->n_mem == 1).

To check that planes are contiguous and have expected size, ie: no
padding. We test the fact that plane 'i' start address + plane 'i'
expected size equals to plane 'i + 1' start address. If not, we return
in error.

Math are done in bufferpool rather than in allocator because the
former is aware of video info.

ac3cb8817e v4l2allocator: let bufferpool calculate image size when importing userptr
Offset are relative to the buffer and there is no guarantee substracting
them will give us the plane size. So we let bufferpool make the math as
it is more aware of video info than allocator and pass a size array to
allocator import function.

8ca40fa86f osxaudiosrc: iOS resampling causes stuttering
Fixes stuttering audio when iOS AU is resampling. To make AU resample,
one has to request a rate that differs from AVAudioSession's
sampleRate. The resampling itself is not the culprit, but rather our
API misuse.

AudioUnitRender modifies the mDataByteSize members with the
actual read bytes count. Therefore, they must be reinitialized
before each AudioUnitRender. (The buffers themselves can be
preallocated.)

The "stutter" was caused by one AudioUnitRender making the buffer
too small for other AudioUnitRender invocations, making them fail
with -50 (paramErr). By way of luck, when AU didn't resample, all
AudioUnitRender invocations read the same number of bytes.

(This patch addresses some non-interleaved audio concerns, but
at this moment the elements do not support non-interleaved audio
and non-interleaved is untested.)

6afd1c5d57 v4l2: Enable copy when no known allocation params
When there is no allocation parameters in the query, enable copy
threshold. When this threshold is reached, the buffer pool will start
copying when the pool reaches a critical level. If the driver supports
CREATE_BUFS, this will be used instead.

dfb0ec6d4d v4l2bufferpool: Update allocator flags
When we hit emulated formats, we disable CREATE_BUFS since libv4l2
cope very badly with it. Also clear the allocator flags so we will
never try to allocate more buffers. This fixes failure when the copy
threshold is reached as we where calling CREATE_BUFS, which lead to
libv4l2 instability.

b91fe36644 v4l2: fraction is reversed
In the fraction 1 / 2. 1 is the numerator and 2 is the denominator.
The arguments of fraction gst_value_set_fractions() are value,
numerator and denominator.
Also, gst_value_set_fraction() fails if denominator is 0 for obvious
reasons.

171bfeccdf v4l2pool: Deactivate other pool
When importing buffers from a downstream pool, we need to deactivate

keeps a reference on their proposed pool.

f5ef99fe5e v4l2allocator: Fix freeing of shared memory
When memory (that has been shared using gst_memory_share()) are freed,
the memory (or the DMABUF FD) should not bee freed. These memories have
a parent. This also removes the extra _v4l2mem_free function and avoid
calling close twice on the DMABUF FD.
