216ee52090 video-info: Properly initialize/set extra fields
The flags and field order weren't properly initialized in the
gst_video_info_init().

Furthermore in gst_video_info_from_caps() we might set unitiliazed
values previously, this only sets them if valid.

47fdb15074 video-info: Add unit test for overflow checks
And also prevent overflows caused by allowing uint width/height in
gst_video_info_set_format() but storing them as (signed!) ints.

f578c00a14 videotimecode: Fix incorrect nsec_since_daily_jam calculation
For drop-frame timecodes, the nsec_since_daily_jam doesn't necessarily
directly correspond to this many hours/minutes/seconds/frames. We have
to get the frame count as per frames_since_daily_jam and then convert.

6e71583d07 Cast away const from GstMetaInfo in *_get_meta_info() functions
MSVC warns about the const in the implicit argument conversion in the
calls to g_once_init_{enter,leave}. It's OK so explicitly cast it.

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.

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.

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.

5c4f4ac1bd 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.

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
timecodes.

cfc36ba586 videodecoder: More trickmode fix
We need to take into account the input segment flags to know whether
we should drain the decoder after a new keyframe in trick mode.

Otherwise we would have to wait for the next frame to be outputted (and
the segment to be activated) which ... well ... kind of beats the whole
point of this draining :)

5e752f4eda video-converter: fix interlaced scaling some more
Fix problem with the line cache where it would forget the first line in
the cache in some cases.
Keep as much backlog as we have taps. This generally works better and we
could do even better by calculating the overlap in all taps.
Allocated enough lines for the line cache.
Use only half the number of taps for the interlaced lines because we
only have half the number of lines.
The pixel shift should be relative to the new output pixel size so scale
it.

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.
