15b8f36be1 avdevice/decklink: fix checking video mode in SDK version 11
Apparently in the new SDK one cannot query if VANC output is supported, so we
will fall back to non-VANC output if enabling the video output with VANC fails.

Fixes ticket #7867.

8732dfa995 avdevice/decklink: Add support for EIA-708 output over SDI
Hook in libklvanc and use it for output of EIA-708 captions over
SDI.  The bulk of this patch is just general support for ancillary
data for the Decklink SDI module - the real work for construction
of the EIA-708 CDP and VANC line construction is done by libklvanc.

Libklvanc can be found at: https://github.com/stoth68000/libklvanc

5409f065f2 avdevice/decklink: Suppress warning about misuse of struct instead of class
When building with Clang, the following warning is shown:

warning: struct 'IDeckLinkVideoFrame' was previously declared as a
class [-Wmismatched-tags]

The function incorrectly casts IDeckLinkVideoFrame as a struct
instead of a class pointer.

77f7d710e0 libavdevice/decklink: add support for 10-bit output for Decklink SDI
Can be tested via the following command:

./ffmpeg -i foo.ts -f decklink -vcodec v210 'DeckLink Duo (1)'

Note that the 8-bit support works as it did before, and setting
the pix_fmt isn't required for 10-bit mode.  The code defaults to
operating in 8-bit mode when no vcodec is specified, for backward
compatibility.

278588cd0b libavdevice/decklink: add support for -sources and -sinks arguments
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.

7f7ee86d5a avdevice/decklink: fix MSVC build issues
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).

9e86a61870 avdevice/decklink: remove pthread dependency
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.
