1 sec might not be enough for the cards to detect the format...

The capture_started variable was never set, it is simpler to call the stop
functions unconditionally if the interface is available.

This option is useful for maintaining input synchronization across N
different hardware devices deployed for 'N-way' redundancy.
The system time of different hardware devices should be synchronized
with protocols such as NTP or PTP, before using this option.

If the user provides a valid timecode_format look for timecode of that
format in the capture and if found store it on the video avstream's
metadata.
Slightly modified by Marton Balint to capture per-frame timecode as well.

The default memory allocator is limited in the max number of frames available,
and therefore caused frame drops if the frames were not freed fast enough.

Create a buffer from the data instead and use the buffer destructor to free the
DeckLink frame. This avoids a memcpy of the frame data.

This changes how NTSC VANC is extracted from the buffer. In NTSC the vanc data
is interleaved between luma and chroma, and not just the luma as in high
definition resolutions.
In my testing this allows a decklink card encoding valid NTSC closed
captions to pass the caption data to the x264 encoder.
Updated with reviews from Devin Heitmueller and Marton Balint.

Add support for enumerating the sources/sinks via the ffmpeg
command line options, as opposed to having to create a real pipeline
and use the "-list_devices" option which does exit() after dumping
out the options.
Note that this patch preserves the existing "-list_devices" option,
but now shares common code for the actual enumeration.
Updated to reflect feedback from Marton Balint <cus@passwd.hu>.

Purpose: Made minor changes to get the decklink avdevice code to build
using Visual C++.
Notes: Made changes to configure per Hendrik Leppkes's review of first
and second versions of patch. Also made slight alterations per Marton
Balint's reviews.
Comments:
-- configure: Added if enabled decklink section and setting
decklink_indev_extralibs and decklink_outdev_extralibs here for
both mingw and Windows. Also eliminated the setting of these
variables in the mingw section earlier in the file.
-- libavdevice/decklink_common.cpp: Switched the order of the include
of libavformat/internal.h to workaround build issues with Visual
C++. See comment in file for more details.
-- libavdevice/decklink_dec.cpp:
a) Rearranged the include of libavformat/internal.h (for reasons as
described above).
b) Made slight alteration to an argument for call to av_rescale_q() to
workaround a compiler error with Visual C++. This appears to only
be an issue when building C++ files with Visual C++. See comment
in code for more details.
-- libavdevice/decklink_enc.cpp: Rearranged the include of
libavformat/internal.h (for reasons as described above).

Purpose: avdevice/decklink: Removed pthread dependency by replacing
semaphore used in code appropriately. Doing so makes it easier to
build ffmpeg using Visual C++ on Windows. This is a contination of
Kyle Schwarz's "avdevice/decklink: Remove pthread dependency" patch
that is available at https://patchwork.ffmpeg.org/patch/2654/ . This
patch wasn't accepted, and as far as I can tell, there was no
follow-up after it was rejected.
Notes: Used Visual Studio 2015 (with update 3) for this.
Comments:
-- configure: Eliminated pthreads dependency for decklink_indev_deps
and decklink_outdev_deps and replaced with threads dependency
-- libavdevice/decklink_common.cpp / .h:
a) Eliminated semaphore and replaced with a combination of a mutex,
condition variable, and a counter (frames_buffer_available_spots).
b) Removed include of pthread.h and semaphore.h and now using
libavutil/thread.h instead.
-- libavdevice/decklink_dec.cpp: Eliminated include of pthread.h and
semaphore.h.
-- libavdevice/decklink_enc.cpp:
a) Eliminated include of pthread.h and semaphore.h.
b) Replaced use of semaphore with the equivalent using a combination
of a mutex, condition variable, and a counter
(frames_buffer_available_spots). In theory, libavutil/thread.h and
the associated code could have been modified instead to add
cross-platform implementations of the sem_ functions, but an
inspection of the ffmpeg source base indicates that there are only
two cases in which semaphores are used (including this one that was
replaced), so it was deemed to not be worth the effort.
