02d3f9748b v4l2object: improve colorspace handling for JPEG sources
gstjpegdec sets 1:4:0:0 colorimetry (full range BT.601 YCbCr encoding
with unknown primaries and unknown transfer function). This currently
gets translated to bt601 or bt709 depending on resolution.
Both cases result in a negotiation failure:

    ERROR: from element /GstPipeline:pipeline0/v4l2video0convert:v4l2video0convert0: Device '/dev/video0' does not support 1:4:0:0 colorimetry

Improve the guessing game by selecting JPEG colorimetry (JPEG colorspace
with sRGB transfer function) under these specific conditions, and loosen
the matching so that 1:4:0:0 input gets accepted if the device is
actually configured to 1:4:7:1 (V4L2_PIX_FMT_JPEG default).

3f360e8f15 v4l2src: fix first input used is always used next times
The input from an v4l2 device that was used the first time was
remembered for next times, and set again always the pipeline is
set to READY state. This was making that users wasn't able to
select a different input without having to create a new pipeline.

This patch makes that v4l2src element forget previous used input
when going to NULL state, so it will check again for the current
selected input when going again to READY state. Users can change
to NULL state, select a new input with a VIDIOC_S_INPUT ioctl
and change to PLAYING again.

9e79821b1d v4l2bufferpool: Validate that capture buffers were queued
When the pool is started, we allocate and release buffer, expecting
the pool release-buffer handler to queue them. Though, as we rely
on release function, there is no direct way to detect that this
process didn't work.

To check this, validate that the number of queued buffer is the same
as the number of allocated buffers. This allow returning an error
when buffer importation was refused by the driver.

38b68cbbd7 v4l2bufferpool: Remove duplicate check
We were calling gst_v4l2_is_buffer_valid() before and inside
gst_v4l2_buffer_pool_qbuf() as we needed to access the group. The second
check failed since the writability of the buffer get inherited from the
GstMemory, which lead to pipeline failure. As we cannot avoid the extra
ref, it would be racy otherwise, just pass the group to _dbuf() so it
does not have to call gst_v4l2_is_buffer_valid() again.

35ab185d75 v4l2videodec: do not call streamon while pool is flushing
gst_v4l2_buffer_pool_flush() executes streamoff for the output, but
streamoff->streamon for the capture of the decoder.
gst_v4l2_buffer_pool_streamon() on capture assumes that is able to
resurrect the buffers from the pool, but acquiring buffers fails if the
buffer pool is still flushing.

The decoder needs to stop flushing the pools before calling
gst_v4l2_buffer_pool_flush() to restart the v4l2 device. Otherwise
starting the decoding thread might fail, because there are no buffers in
the capture pool.

This fixes a regression that was introduced in 97985a335c
("v4l2videodec: Add dynamic resolution change support").

4632f33334 v4l2deviceprovider: Don't do slow probes
This is problematic in the current design at it seriously slow down
startup of applications. As of now, no known application uses the
colorimetry and the interlace-modes for anything (the two fields that
won't be probed). So let's disable it, in the long term we'll try and
find a way to interact with the provider so applicaiton could opt-in
these slow probing methods for more advance configuration.

4026211154 v4l2object: Don't use mmap64 if off_t is 64-bit
The difference between mmap and mmap64 is the type of 'offset' argument.
mmap64 always uses a 64-bit interger as offset, while mmap uses off_t,
whose size can vary on different operating systems or architectures.

However, not all operating systems support mmap64. Fortunately, although
FreeBSD only has mmap, its off_t is always 64-bit regardless of
architectures, so we can simply use mmap when sizeof(off_t) == 8.

5e05cadb17 v4l2videodec: Handle drivers that only round up height
Commit 1f31715c98 ("v4l2videodec: use visible size, not coded size,
for downstream negotiation filter") added support for removing the
padding obtained as the difference between width/height from G_FMT and
visible width/height from G_SELECTION from the probed caps obtained
via TRY_FMT.
This patch fixes the padding removal for drivers that only round up
height, but not width, to the padded frame size. This might happen
because horizontal padding can be handled by line stride (bytesperline),
but there is no such thing as plane stride in the V4L2 API for
single-buffer planar formats.

57d7ae8496 v4l2allocator: Add support for data_offset
In MPLANE mode, the driver may set data_offset, which represent some
padding at the start of the buffer used internally. This portion of the
data need to be skipped, though it is included in bytesused.

This patch removes frame size sanity check as the method used will no
longer work. This check was simply there to help detect broken kernel
drivers. It would be re-implement by estimating the plane size, which is
not totally trivial and may be too much work for a simple debug check.

b3e089d415 v4l2src: Speedup camera startup by skipping try_fmt
In this commit, we enabled skip_try_fmt_probes quirk in order to speed
up the start which is known to be disastrously slow with certain USB
cameras.

This has the side effect that we needed to rewrite the entire
negotiation process in a way that we iterate over the possible caps
until we find one that works.

The new negotiation method consist of extracting a preferred structure
from the peer caps and using this to fixate and sort the caps. To
reflect the old behaviour, we sort all resolution strictly bigger
to the preferred one with the closes one first. The rest is appended,
keeping the same order. We then normalize the caps in case there was
some list of interlace-mode or colorimetry left. We finally iterate
over all fixed caps and try it. 99% of the time, the first or the
second one should work, whit the result of a single S_FMT being issues.

From there, it will be relatively easy to introduce new negotiation
algorithm. The current algorithm is made for optimal image quality
with a scaling sink that sets it's window resolution as preference.
This the case if for:

  v4l2src ! videoconvert ! videoscale ! ximagesink

Other strategy would be needed to optimize for non-scaling sink like
ximagesink or kmssink when the driver does not scale.

cae0b9a2d2 v4l2object: Introduce quirk to skip slow probes

interlace-mode and colorimetry to avoid relying on try_fmt. This quirk
will be used by v4l2src to avoid desastrous startup time with slow
USB webcams.

When this quirk is enabled, caller will have to iterate over the
negotiated caps as it may contains unsupported formats. If the peer
didn't choose a specific interlace-mode, or colorimetry, the value
chosen by the driver is set into the caps. For this reason, when this
mode is enabled, gst_v4l2_object_set_format() will require writable
caps.

724a3ceec5 v4l2videodec: Implement stable element names
Before that, each m2m node would be wrapped as a single, multi-format
decoder element. As a unique name was needed, we where using the device
name, which changes between re-boots. This led to unpredictable element
names. In this patch, we generate an element per codec, using
v4l2<codec>dec name. If there is multiple decoder for the same format,
the following elements will be named v4l2<node><codec>dec.

47ca2ce499 v4l2: increase by one the number of allocated buffers
Increasing this number fix a buffer starvation problem I'm hitting
with a "v4l2src ! kmssink" pipeline.

kmssink requests 2 buffer as it keeps a reference on the last rendered
one. So we were allocating 3 buffers for the pipeline.
Once the first 2 buffers have been pushed we ended up with:
- one buffer queued in v4l2
- one being pushed
- one kept as last rendered

If this 3rd buffer is released after that v4l2 used the first one to
capture we end up with a buffer starvation problem as no buffer is currently
queued in v4l2 for capture.

Fixing this by adding one extra buffer to the pipeline so when one
buffer is being pushed downstream the other can already be queued to
capture the next frame.

We were already adding 3 buffers if downstream didn't reply to the
allocation query. I reduced this number to 2 to compensate the extra
buffer which is now always added.

27310365d5 v4l2: Add Video Encoder support
This implements H264 encoding support using generic V4L2 interface. It is
reported to work with Samsung MFC driver, IXM.6 CODA driver and
Qualcomm mainline Venus driver. Other platform should be supported as
none of this work is platform specific.

The implementation consist of a GstV4l2VideoEnc base class, which
implements the core streaming functionality. This base class is implemented
by GstV4l2H264Enc class that implements the caps negotiation specific to
H264 profiles and level. This implementation supports hardware with multiple
H264 encoder. Though, to make it simplier to use, the first discovered H264
encoder will be named v4l2h264enc. Other encoder found during discovery will
have a unique name like v4l2video0h264enc.

This work is the combined work of multiple developpers in the last 3
years. Thanks to all of the contributors:

Fixes https://bugzilla.gnome.org/show_bug.cgi?id=773681

We have to do polling here because the event notification API that
Directsound exposes cannot be used with live playback since all events
must be registered in advance with the capture buffer, you cannot
add/remove them once playback has begun. Directsoundsrc had the same
problem.

Running `gst-validate-launcher -t validate.file.playback.change_state_intensive.vorbis_vp8_1_webm`

This happens when the following race happens:

- T0: Main thread
- T1: Upstream streaming thread
- T2. v4l2dec processing thread)

[The decoder is in PAUSED state]

T0. The validate scenario runs `Executing (36/40) set-state: state=null repeat=40`
T1- The decoder handles a frame
T2- A decoded frame is push downstream
T2- Downstream returns FLUSHING as it is already flushing changing state
T2- The decoder stops its processing thread and sets `->processing = FALSE`
T1- The decoder handles another frame
T1- `->process` is FALSE so the decoder restarts its streaming thread
T0- In v4l2dec-> stop the processing thread is stopped
NOTE: At this point the processing thread loop never started.
T0- assertion failed: (g_atomic_int_get (&self->processing) == FALSE)

Here I am removing the whole ->processing logic to base it all on the
GstTask state to avoid duplicating the knowledge.

ce5c0b8f92 v4l2object: set streamparm for outputs that support it
Without a specified framerate from the sink, the decoder frame interval
should be set using the framerate of the encoded video stream.
Therefore, the v4l2object should be able to change the framerate on the
output if the V4L2 device accepts it.

This is also necessary for mem2mem encoders so that their bitrate
calculation code may work correctly and they may report the correct
frame duration on the capture queue.

If the duration of the v4l2object is GST_CLOCK_TIME_NONE, because the
sink did not specify a framerate in the caps and the driver accepts the
framerate, the decoder element uses GST_CLOCK_TIME_NONE to calculate and

not use the invalid duration to calculate a latency, but print a warning
instead.

7f763f2710 v4l2allocator: reference memory before the buffer is queued
In gst_v4l2_allocator_qbuf(), the memory is referenced after the
buffer is queued. Once queued (VIDIOC_QBUF), the buffer might be handled
by the V4L2 driver (e.g. decoded) and dequeued (gst_v4l2_allocator_dqbuf),
through a different thread, before the memory is referenced (gst_memory_ref).
In this case, in gst_v4l2_allocator_dqbuf(), the memory is unreferenced
(gst_memory_unref) before having been referenced: the memory refcount
reaches 0, and the memory is freed.
So, to avoid this crossing case, in gst_v4l2_allocator_qbuf(), the
memory shall be referenced before the buffer is queued.

56b1d088a9 v4l2: Warn, don't assert if v4l gives us a buffer with a too large size
I've seen problems where the `bytesused` field of `v4l2_buffer` would be
a silly number causing the later call to:

    gst_memory_resize (group->mem[i], 0, group->planes[i].bytesused);

to result in this error to be printed:

    (pulsevideo:11): GStreamer-CRITICAL **: gst_memory_resize: assertion 'size + mem->offset + offset <= mem->maxsize' failed

besides causing who-knows what other problems.

We make the assumption that this buffer has still been dequeued correctly
so just clamp to a valid size so downstream elements won't end up in
undefined behaviour.

The invalid `v4l2_buffer` I saw from my capture device was:

    buffer = {
      index = 0,
      type = 1,
      bytesused = 534748928, // <- Invalid
      flags = 8260, // V4L2_BUF_FLAG_TIMESTAMP_MONOTONIC | V4L2_BUF_FLAG_ERROR | V4L2_BUF_FLAG_DONE
      field = 01330, // <- Invalid

b09f478e80 Add support for Meson as alternative/parallel build system
https://github.com/mesonbuild/meson

With contributions from:

Tim-Philipp Müller <tim@centricular.com>
Jussi Pakkanen <jpakkane@gmail.com> (original port)

Highlights of the features provided are:
* Faster builds on Linux (~40-50% faster)
* The ability to build with MSVC on Windows
* Generate Visual Studio project files
* Generate XCode project files
* Much faster builds on Windows (on-par with Linux)
* Seriously fast configure and building on embedded

... and many more. For more details see:

http://blog.nirbheek.in/2016/07/building-and-developing-gstreamer-using.html

Building with Meson should work on both Linux and Windows, but may
need a few more tweaks on other operating systems.

D3DX has been deprecated for the last 4 years and latest versions of
Windows no longer ship headers for it. This is fine as long as you're
building with Cerbero's Wine-based DirectX headers, but sucks if you
want to build against the actual Windows SDK.

We were just using it to get error strings anyway, so just use the
generic error string API.

The gst_v4l2_object_acquire_format() function is used by v4l2videodec to obtain
the currently set capture format. Since G_FMT returns the coded size, the
visible size needs to be obtained from the compose rectangle in order to
negotiate it with downstream elements. The G_CROP call hasn't worked on mem2mem
capture queues for a long time. Instead use the G_SELECTION call to obtain the
compose rectangle and only fall back to G_CROP for ancient kernels.

b18031cf4b v4l2sink: Use V4L2_BUF_TYPE_VIDEO_OUTPUT_OVERLAY if driver advertises it.
On modern kernels, the G/S_FMT ioctls will always fail using
V4L2_BUF_TYPE_VIDEO_OVERLAY with VFL_DIR_TX (e.g. real overlay out drivers)
since this is not the intented use (rather rx, according to v4l2 API doc).
Probably this is why the Video Output Overlay interface was created, so if
the driver advertises it we might as well use.
For old kernels (pre 2012) the old way might still work so keeping this for
compatibility.

df9eed0ab5 v4l2: Change warning handling to break infinite message loop
v4l2src can cause an "infinite message loop" when a base control exposed as a
property is not provided by the device. In these cases, if in the warning message
handling for the bus, the GST_DEBUG_BIN_TO_DOT_FILE* category of functions are used,
the src lookup causes a new warning to be posted on the bus, causing a loop.

This patch changes the warning for these controls so they are not posted on the bus.

c163250f0d v4l2object: probe all colorspace supported by device
A device can support more than one colorspace for a given image
dimension and pixel format. So we have to probe all the supported
colorspace and not only rely on the default one. Otherwise we could end
up with negotiation failure if the caps colorimetry field don't match
the v4l2 device default one even if the v4l2 could support such
colorimetry.

This patch enable probing if colorspace for both capture and output
device. It really makes sense for output device since the colorspace
shall be set by the application and a little less for capture device
which, at the moment, shall provide the colorspace; ie: the v4l2
specification seems to not take into account the fact that a capture
device could do colorspace conversion.

As a side effet, probing takes some times and so sligthly delay v4l2
initialization. Note that this patch only probe colorspace and not all
colorspace, matrix, transfer and range combination to avoid taking too
much time, especially with low-speed devices as full probing do 1782
ioctl.
