* avdevice/decklink_dec: fix codec_tag of RGBA formatsBIGLER Don (Framatome)2018-11-01
| | | | | | Fixes ticket #7505. Signed-off-by: Marton Balint <cus@passwd.hu>
* avdevice/decklink_dec: add option to align capture start timeKarthick Jeyapal2018-09-30
| | | | | | | | | 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. Signed-off-by: Marton Balint <cus@passwd.hu>
* avdevice/decklink_dec: capture timecode to metadata when requestedJon Morley2018-06-13
| | | | | | | | | | 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. Signed-off-by: Marton Balint <cus@passwd.hu>
* avdevice/decklink_dec: use std::atomic for decklink_input_callback refcountingMarton Balint2018-06-13
| | | | | | Also remove the callback from the context, and add proper error handling. Signed-off-by: Marton Balint <cus@passwd.hu>
* avdevice/decklink_dec: use a custom memory allocatorMarton Balint2018-06-13
| | | | | | | 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. Signed-off-by: Marton Balint <cus@passwd.hu>

* avdevice/decklink_dec: do not copy video dataMarton Balint2018-04-30
| | | | | | | 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. Signed-off-by: Marton Balint <cus@passwd.hu>

* avdevice/decklink_dec: extract NTSC VANCRay Tiley2018-02-13
| | | | | | | | | | | | | | 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.

* libavdevice/decklink: add support for -sources and -sinks argumentsDevin Heitmueller2017-10-10
| | | | | | | | | | | | | | | 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>.

* avdevice/decklink: fix MSVC build issuesAaron Levinson2017-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* avdevice/decklink: remove pthread dependencyAaron Levinson2017-04-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
