8305cb2995 meson: find libjpeg via pkg-config
This effectively (but optionally) requires libjpeg-turbo which
ships with a .pc file and is what pretty much everyone these days
uses anyway for libjpeg, so shouldn't be a problem hopefully.

8f807477eb meson: Add feature options for all plugins
Checks for GL, Qt5, and C++ are still automagic. FIXMEs have been
added for these so they can be fixed later.

ba86a1d99c jpegenc: add snapshot property
Like pngenc, automatically send an EOS message.

Example of bin:
appsrc ! jpegenc snapshot=true ! filesink location=out.jpg

This is especially useful for limited/slow hardware.

Otherwise calling gst_video_convert_sample() is a better option
(internally uses videoconvert and videoscale).

10ff3c8e14 jpeg: Fixup frames without an EOI marker
Some cameras fail to send an end-of-image marker (EOI)
and can't be properly decoded by either JPEG or libjpeg.

This commit parses the frame, making sure it has an EOI.
If there isn't one, the EOI gets added to the buffer.

A similar fixup is done in the rtpjpegdepay element,
and it makes sense to do it in jpegdec as well.

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.

a6008fde65 jpegdec: Wait for segment event before checking it
The heuristic to choose between packetise or not was change to use the
segment format. The problem is that this change is reading the segment
during the caps event handling. The segment event will only be sent
after. That prevented the decoder to go in packetize mode, and avoid
useless parsing.

905e28a0f3 jpegdec: Don't pass the same data over and over
We already pass the entire frame to the decoder. If the decoder ask for
more data, don't pass the same data again as this leads to infinit loop.
Instead, simply fail the fill function to signal the problem with that
frame. It will then be skipped properly.

7ef9dd3761 jpegdec: fix output state memory leak
When jpeg_finish_decompress is called, output state reference is being created.
But if there is any failures in finishing decompress, it jumps to setjmp,
and at that point state was not referenced. Resulting in leak of output state.
Hence adding another setjmp after output state is referenced.
Similarly adding another setjmp to unmap the frame in case error happens before
finish_decompress

1421fc558e jpegdec: fix frame leaks in handle_frame() implementation

gst_video_decoder_drop_frame() or gst_video_decoder_finish_frame() we have to
release it manually.

448b1ac2b1 jpeggdec: modify wrong packetized mode logic
packetized mode is being set when framerate is being set
which is not correct. Changing the same by checking the
input segement format. If input segment is in TIME it is
Packetized, and if it is in BYTES it is not.

Now that the subset check actually works, this breaks

to plug either yet.
