This also add supports for 4K DeckLink cards because they always output the ancillary data in 10-bit. v2: - only try teletext decoding for 576i PAL mode - some comments as requested by Aaron Levinson Signed-off-by: Marton Balint <cus@passwd.hu>

Using AVOnce as a stack variable makes no sense as the state is lost when the function exits. This fixes repeated calls to av(filter/device)_register_all

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.

The framework will allocate a buffer and copy the data to it, that takes time. But it avoids constently creating and destroyng the shared memory segment, and that saves more time. On my setup, from ~200 to ~300 FPS at full screen (1920×1200), from ~1400 to ~3300 at smaller size (640×480), similar to legacy x11grab and confirmed by others. Plus, shared memory segments are a scarce resource, allocating potentially many is a bad idea. Note: if the application were to drop all references to the buffer before the next call to av_read_frame(), then passing the shared memory segment as a refcounted buffer would be even more efficient, but it is hard to guarantee, and it does not happen with the ffmpeg command-line tool. Using a small number of preallocated buffers and resorting to a copy when the pool is exhausted would be a solution to get the better of both worlds.

sigaction is not defined in standards as a struct starting with another struct. Some *BSD variants do however, resulting in a warning from the zero initialization, which this change eliminates. This partially reverts a92be9b8.
