54f4d3772c audio-channels: map buffer read-write only if channels differ
gst_audio_buffer_reorder_channels() was always mapping the buffer read-write
regardless whether any reordering was needed.  If the from and to channel order
is identical return immediately without remapping the buffer.

Add a small helper function gst_audio_channel_positions_equal() which is used
in both gst_audio_reorder_channels() and gst_audio_buffer_reorder_channels().

3bf893e12a video: add gst_video_decoder_allocate_output_frame_with_params
It adds a third argument to pass GstBufferPoolAcquireParams
to gst_buffer_pool_acquire_buffer.

If a user subclasses GstBufferPoolAcquireParams, this allows to
pass an updated param to the underlying buffer pool at each
gst_video_decoder_allocate_output_frame_with_params call.

f5eb366335 allocators: define GST_CAPS_FEATURE_MEMORY_DMABUF
Adds "memory:DMABuf" caps feature. Since 1.11 tag.
Useful when the the dma-buf buffer cannot be mapped to CPU for r/w requests.
Example: protected content or platform constraints.

79809633de video-info: Add optional field-order caps field for interlaced-mode=interleaved
Usually this information is static for the whole stream, and various
container formats store this information inside the headers for the
whole stream.

Having it inside the caps for these cases simplifies code and makes it
possible to express these requirements more explicitly with the caps.

89e711663f audioclock: use GstAudioClock* as first argument in GstAudioClock methods
All the GstAudioClock method declarations required object of GstClock type
as a first argument, but in fact, required GstAudioClock object (runtime
check in function body). Instead of checking type in run-time, we can
change functions declaration, to accept only GstAudioClock methods. Then,
runtime check is not necessary anymore, since always GstAudioClock object
is passed to a function.

92392a4733 videodecoder: Default caps sets format I420
Also the format must be fixed on the default raw caps. If not
gst_video_info_from_caps() will fail and
gst_video_decoder_negotiate_default_caps() return FALSE.

The test simulates the use case where a gap event is received before
the first buffer causing the decoder to fall back to the default caps.

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.

41c9f0b9dc videotimecode: Fix false positive coverity issues
They are false positive overflows, because coverity doesn't realize that
hours <= 24, minutes < 60 and seconds < 60 in all functions. Also casting the
number 60 (seconds in minute, minutes in hour) to guint64 for the
calculations, in order to avoid overflowing once we allow more than 24-hour

9adaeb0a71 riff: Remove sample rate and channel count boundaries in caps
WAV is too generic to impose more-or-less arbitrary boundaries on the
sample rate and channel count caps. For example, there are 384 kHz WAV
files. Another example: it is in theory possible that somebody puts DSD
data into a WAV file, which will then have a sample rate of ~2.8 MHz.

For this reason, get rid of the rate and channel caps unless they are
fixed values. Downstream anyway usually knows the limitations better.

c6722c06a0 appsink: add _pull_sample/preroll() variants with timeout
The _pull_sample() and _pull_preroll() functions block
until a sample is available, EOS happens or the pipeline
is shut down (returning NULL in the last two cases).

This adds _try_pull_sample() and _try_pull_preroll()
functions with a timeout argument to specify the maximum
amount of time to wait for a new sample.

To avoid code duplication, wait forever if the timeout is
GST_CLOCK_TIME_NONE and use that to implement
_pull_sample/_pull_preroll with the original behavior.

Add also corresponding action signals "try-pull-sample"
and "try-pull-preroll".

a2c050a4be tagdemux: fix handling of very short files in push mode
By default we'll wait for a certain amount of data before
attempting typefinding. However, if the stream is fairly
short, we might get EOS before we ever attempted any
typefinding, so at this point we should force typefinding
and output any pending data if we manage to detect the
type.

8d4f79b640 audiodecoder: fix invalid timestamps when PLC and delay
Elements inherited from GstAudioDecoder, supporting PLC and introducing
delay produce invalid timestamps. Good example is opusdec with in-band FEC
enabled. After receiving GAP event it delays the audio concealment until
the next buffer arrives. The next buffer will have DISCONT flag set which
will make GstAudioDecoder to reset it's internal state, thus forgetting
the timestamp of GAP event. As a result the concealed audio will have the
timestamp of the next buffer (with DISCONT flag) but not the timestamp
from the event.

5dd720e064 exiftag: Increase serialized geo precision
The serialization of double typed geographical
coordinates to DMS system supported by the exif
standards was previously truncated without need.

The previous code truncated the seconds part of
the coordinate to a fraction with denominator
equal to 1 causing a bug on the deserialization
when the test for the coordinate to be serialized
was more precise.

This patch applies a 10E6 multiplier to the numerator
equal to the denominator of the rational number.

Eg. Latitude = 89.5688643 Serialization

DMS Old code = 89/1 deg, 34/1 min, 7/1 sec
DMS New code = 89/1 deg, 34/1 min, 79114800UL/10000000UL

Deserialization

DMS Old code = 89.5686111111
DMS New code = 89.5688643

The new test tries to serialize a higher precision
coordinate.

The types of the coordinates are also guint32 instead
of gint like previously. guint32 is the type of the
fraction components in the exif.

8b8708f946 videodecoder: handle buffer's flags at offset
For reverse playback it is important to handle correctly the frame sync
points, which is set when the input buffer doesn't have the DELTA_UNIT flag.

This is handled correctly when decoder is packetized, but when it is not the
frame's sync point is not copied, and the reverse playback never decodes frame
batches.

The current patch adds the buffer's flags to the Timestamp list, where the
timestamp and duration of the input buffers are hold.

b4a695cd11 libs: video: split allocation query caos and pad caps
Since the allocation query caps contains memory size and the pad's caps
contains the display size, a video encoder or decoder might need to allocate
a different frame size than the size negotiated in the caps.

This patch splits this logic distinction for videodecoder and videoencoder.

The user if needs a different allocation caps, should set the allocation_caps
in the GstVideoCodecState before calling negotiate() vmethod. Otherwise the
allocation_caps will be the same as the caps set in the src pad.

7a206336dd rtpbasedepayload: look at ssrc before sequence numbers
Doing so prevents us dropping buffers in the rare, but possible, situations,
when the stream changes SSRC and new sequence numbers does not differ
much from the last sequence number from previous SSRC. For example:
ssrc - 0xaaaa 101,102,103,104 ssrc - 0xbbbb 102, 103, 104, 105...
In the scenario above we don't want to drop the first 3 packets of
0xbbbb stream.

2102fdc983 discoverer: copy over result and seekable fields when copying a discoverer info
The function gst_discoverer_info_copy doesn't copy the data members seekable
and result of the source GstDiscovererInfo.

In the case of copying a GstDiscovererInfo for later use, the seekbale will be
undefined, which in practice usually will be false, even though the seekable of
the original GstDiscovererInfo is true.
