612102fdbc gst: don't use volatile to mean atomic
volatile is not sufficient to provide atomic guarantees and real atomics
should be used instead.  GCC 11 has started warning about using volatile
with atomic operations.

ba4b9971e9 vp8enc: expect bps for temporal-scalability-target-bitrate.
Consistency with target-bitrate is less surprising and with
modern libvpx additional configuration is required to make
temporal scaling work.

d9cedee042 vp8enc: finish support for temporally scaled encoding
- introduce two new properties:

    * temporal-scalability-layer-flags:

      Provide fine-grained control of layer encoding to the
      outside world. The flags sequence should be a multiple of
      the periodicity and is indexed by a running count of encoded
      frames modulo the sequence length.

    * temporal-scalability-layer-sync-flags:

      Specify the pattern of inter-layer synchronisation (i.e.
      which of the frames generated by the layer encoding
      specification represent an inter-layer synchronisation).
      There must be one entry per entry in
      temporal-scalability-layer-flags.

  - apply temporal scalability settings and expose as buffer
    metadata.

    This allows the codec to allocate a given frame to the correct
    internal bitrate allocator. Additionally, all the
    non-bitstream metadata needed to payload a temporally scaled
    stream is now attached to each output buffer as a
    GstVideoVP8Meta.

  - add unit test for temporally scaled encoding.

39fcc7f58f vp9enc: expose row-mt property
With recent libvpx versions, multithreading can be enabled on
a per-tile basis, instead of on a per tile-column basis.

In combination with the new tile-rows property, this allows the
encoder to make much better use of the available CPU power.

Bump minimum libvpx version to 1.7.0

7b390a8bbd vpxenc: Add new bit-per-pixel property to select a better "default" bitrate
As part of this also change the default bitrate value to 0. The default
value was 256000 previously. In reality, if the property was not set the
bitrate value would be scaled according to the resolution which is not
very intuitive behavior. It is better to use 0 for this purpose. Now
together with newly introduced property "bits-per-pixel" 0 means to
assign the bitrate according to resolution/framerate.

The default bitrates are now
 - 1.2Mbps for VP8 720p@30fps
 - 0.8Mbps for VP9 720p@30fps
and scaled accordingly for different resolutions/framerates.

Previously the default bitrate was also not scaled according to the
framerate but only took the resolution into account.

This also fixes the side effect of setting bitrate to 0. Previously
encoder would not produce any data at all.

Addition from Sebastian Dröge <sebastian@centricular.com> to assume
30fps if no framerate is given in the caps instead of not calculating
any bitrate at all.

44e4de43da vpxdec: Check that output width and height != 0
For VP8 it's possible to signal width or height to be 0, but it does
not make sense to do so. For VP9 it's impossible. Hence, we most
likely have a corrupt stream. Trying to negotiate caps downstream with
either width or height as 0 will fail with something like

gst_video_decoder_negotiate_default: assertion 'GST_VIDEO_INFO_WIDTH (&state->info) != 0' failed

88ce7397fc vp8enc/vp8enc: set 1 for the default value of VP8E_SET_STATIC_THRESHOLD
In Google webrtc, the setting VP8E_SET_STATIC_THRESHOLD is set to 1
(except when the content is known to be static very often in which
case it is set to 100, i.e. when sharing screen with Google Hangouts).

The cpu usage drops a lot when using 1 for above setting because it
allows the encoder to skip static/low content blocks. The current
0 default value uses too much cpu and confuses the user regarding
the cpu usage expectations. User expects vp8enc to use low cpu by
default.

36fc2a747a vpxenc: discard frames that have been dropped by libvpx
This fixes a memory leak. When dropframe-threshold has been set,
libvpx may output less frames than the input ones, which causes
some GstVideoCodecFrames to queue up in GstVideoEncoder's internal
frame queue with no chance of ever being all released. And because
the frames keep references to the input buffers, the input buffer
pool keeps allocating new buffers and memory usage grows very fast.
For example the following pipeline's memory usage grows at a rate
of about 1GB per minute!

videotestsrc ! capsfilter caps=video/x-raw,width=1920,height=1080,framerate=30/1,format=I420 ! \

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.

8740313504 vpxenc: Properly handle frames with too low duration
When a frame's duration is too low, calling gst_util_uint64_scale()
to scale its value can result into it being truncated to zero, which
will cause the vpx encoder to return an VPX_CODEC_INVALID_PARAM error
when trying to encode.

To prevent this from happening, we simply ignore the duration when
encoding if it becomes zero after scaling, logging a warning message.
