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

dfb0ec6d4d v4l2bufferpool: Update allocator flags
When we hit emulated formats, we disable CREATE_BUFS since libv4l2

81e15d22c0 osxvideosink: Disable hack for NSApp iteration with a special #define
The hack causes deadlocks and other interesting problems and it really
can only be fixed properly inside GLib. We will include a patch for
GLib in our builds for now that handles this, and hopefully at some
point GLib will also merge a proper solution.

A proper solution would first require to refactor the polling in
GMainContext to only provide a single fd, e.g. via epoll/kqueue
or a thread like the one added by our patch. Then this single
fd could be retrieved from the GMainContext and directly integrated
into a NSRunLoop.

e7b10a107d osxaudio: Fix deadlock and property change notification in device selection code
After creating the ringbuffer we have to set the device on the ringbuffer as
it defaults to kAudioDeviceUnknown. At this point it can't have changed to
anything else yet and we don't have to notify about changes to the sink/src
"device" property. It's also not a good idea because GstAudioBaseSrc has the
object lock taken while the ringbuffer is created, which might cause a
deadlock if something calls back into the element from "notify::device".

Once the base class is done with the NULL_TO_READY state change, it has opened
the device via the ringbuffer and this might have chosen a different device.
Especially if we initially used kAudioDeviceUnknown. Also notify about this
property change as initially intended by this code.

3dae65ede8 v4l2object: Always set format
Right now we try to be clever by detecting if device format have
changed or not, and skip setting format in this case. This is valid
behaviour with V4L2, but it's also very error prone. The rational
for not setting these all the time is for speed, though I can't
measure any noticeable gain on any HW I own. Also, until recently,
we where doing get/set on the format for each format we where
probing, making it near to impossible that the format would match.
This also fixes bug where we where skipping frame-rate setting if
format didn't change.

02040d507c v4l2: Clean up interlace support
Rather than try and guess interlace support as part of checking supported
sizes, look for interlace support specifically in its own function.

As a cleanup, use V4L2_FIELD_ANY when probing sizes, which should result in
the driver doing the right thing.

With my capture setup, this gets me the following sample caps:

For 1080i resolution:
video/x-raw, format=(string)YUY2, width=(int)1920, height=(int)1080, pixel-aspect-ratio=(fraction)1/1, interlace-mode=(string)interleaved, framerate=(fraction){ 25/1, 30/1 }

For 720p resolution:
video/x-raw, format=(string)YUY2, width=(int)1280, height=(int)720, pixel-aspect-ratio=(fraction)1/1, interlace-mode=(string)progressive, framerate=(fraction){ 50/1, 60/1 }

For 576i/p resolution (both possible at the point of query):
video/x-raw, format=(string)YUY2, width=(int)720, height=(int)576, pixel-aspect-ratio=(fraction)1/1, interlace-mode=(string){ progressive, interleaved }, framerate=(fraction){ 25/1, 50/1 }

This, in turn, makes 576i work correctly; with the old code,
the caps would be interlace-mode=progressive for interlaced video.

1dcc883261 v4l2bufferpool: cleanly handle streamon failure for output device
On streamon failure, the queued buffer is not released from the
bufferpool class point of view because it is queued to the driver and
the flush logic is not performed since we are not in streaming state.
It causes the v4l2 bufferpool to always return that stop method failed
and to leak v4l2 objects and buffers.

This commit solve this by performing the flush logic in error case, ie
flushing the allocator and restoring queued buffer state to non-queued.

7554bd3916 ximagesrc: Draw the cursor only when it is active in the capturing region
Use XQueryPointer to check that the pointer is actually active inside
the capturing region.

This prevents drawing the cursor when the pointer is partially outside
of the captured region but not active inside the region; in particular
this avoids drawing the "window resize" cursor shapes to the captured
image when the mouse pointer crosses a window border.

NOTE that this is not only an optimization, this also happen to fix
a serious problem in multi-screen setups.

Because XFixes gives no information of what screen the pointer is on,
ximagesrc was always drawing the cursor on the captured screen even if
the mouse pointer was on another screen.

For example, when capturing from screen 1 (i.e. display-name=":0.1") the
cursor was drawn in the captured image even when the mouse pointer was
actually on screen 0, which is wrong and visually confusing.

3705f08bad ximagesrc: Fix drawing the cursor when it is outside the capturing region
When the cursor is partially or totally out of the capturing region on
the top side or on the left side, it gets drawn fully inside of the
region with its coordinates rounded up to the left or to the top border.

This is immediately noticeable when using the xid property to capture
a specific window.

To fix the issue, allow negative cx and cx coordinates when checking the
boundaries before drawing the cursor.

NOTE that the boundaries checking calculations still allows the cursor
to be drawn when it is only partially outside of the capturing region,
but this makes sense and gives a more pleasing visual behaviour.

cb70a7f6a7 ximagesrc: Fix the destination coordinates of the cursor
XFixes provides the cursor coordinates relative to the root window, this
is not taken into account when using the xid property to capture
a specific window, the result is that the cursor gets drawn at the wrong
position.

In order to fix this consider the window location when calculating the
cursor position in the destination image.

This will prevent the converter to be picked automatically in case

a converter suited for general purpose. Re-negotiation is also needed

5c933fa781 v4l2allocator: Workaround driver that don't support REQBUFS(0)
There is still around 18 drivers not yet ported to videobuf2. These driver
don't support freeing buffetrs through REQBUFS(0) hence for these the
memory type probing fails. In order to gain back our previous behaviour in
presence of these, we implement a workaround that assuming MMAP is
supported. Note that an allocator is only created for device with
STREAMING support in the device capabilities. In such case one of MMAP,
USERPTR and DMABUF is required. Though DMABUF came afterward, so is
not an option and in practice none of these drivers will only do USERPTR.

116649371e v4l2: get_nearest_size: Fix "Unsupported field type" errors
Most V4L2 ioctls like try_fmt will adjust input fields to match what the
hardware can do rather then returning -EINVAL. As is docmented here:
http://linuxtv.org/downloads/v4l-dvb-apis/vidioc-g-fmt.html

EINVAL is only returned if the buffer type field is invalid or not supported.

So upon requesting V4L2_FIELD_NONE devices which can only do interlaced
mode will change the field value to e.g. V4L2_FIELD_BOTTOM as only returning
half the lines is the closest they can do to progressive modes.

In essence this means that we've failed to get a (usable) progessive mode
and should fall back to interlaced mode.

This commit adds a check for having gotten a usable field value after the first
try_fmt, to force fallback to interlaced mode even if the try_fmt succeeded,
thereby fixing get_nearest_size failing on these devices.
