* avfilter/ccfifo: remove unnecessary context allocationsJames Almer2023-05-121-1/+1
| | | | | | | This is not public API, no it has no need for an alloc() and free() functions. The struct can reside on stack. Signed-off-by: James Almer <jamrial@gmail.com>
* avdevice/decklink: move AVPacketQueue into decklink_common and rename it to ↵Devin Heitmueller2023-05-111-3/+10
| | | | | | | | | | | | | | | | | | | | DecklinkPacketQueue Move the AVPacketQueue functionality that is currently only used for the decklink decode module into decklink_common, so it can be shared by the decklink encoder (i.e. for VANC insertion when we receive data packets separate from video). The threadsafe queue used within the decklink module was named "AVPacketQueue" which implies that it is part of the public API, which it is not. Rename the functions and the name of the queue struct to make clear it is used exclusively by decklink, per Marton Balint's suggestion.

* avdevice/decklink_enc: add support for playout of 608 captions in MOV filesDevin Heitmueller2023-05-111-0/+3
| | | | | | | | | | | | | | | | | Unlike other cases where the closed captions are embedded in the video stream as MPEG-2 userdata or H.264 SEI data, with MOV files the captions are often found on a separate "e608" subtitle track. Add support for playout of such files, leveraging the new ccfifo mechanism to ensure that they are embedded into VANC at the correct rate (since e608 packets often contain batches of multiple 608 pairs). Note this patch includes a new file named libavdevice/ccfifo.c, which allows the ccfifo functionality in libavfilter to be reused even if doing shared builds. This is the same approach used for log2_tab.c. Signed-off-by: Devin Heitmueller <dheitmueller@ltnglobal.com> Signed-off-by: Limin Wang <lance.lmwang@gmail.com>
* avdevice/decklink_enc: don't take for granted that first frame to decklink ↵Devin Heitmueller2023-03-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | output will be PTS 0 The existing code assumed that the first frame received by the decklink output would always be PTS zero. However if running in other timing modes than the default of CBR, items such as frame dropping at the beginning may result in starting at a non-zero PTS. For example, in our setup because we discard probing data and run with "-vsync 2" the first video frame scheduled to the decklink output will have a PTS around 170. Scheduling frames too far into the future will either fail or cause a backlog of frames scheduled far enough into the future that the entire pipeline will stall. Issue can be reproduced with the following command-line: ./ffmpeg -copyts -i foo.ts -f decklink -vcodec v210 -ac 2 'DeckLink Duo (4)' Keep track of the PTS of the first frame received, so that when we enable start playback we can provide that value to the decklink driver. Thanks to Marton Balint for review and suggestion to use AV_NOPTS_VALUE rather than zero for the initial value.

* avcodec/packet_internal: Add proper PacketList structAndreas Rheinhardt2022-01-041-1/+4
| | | | | | | | | | | | | | | Up until now, we had a PacketList structure which is actually a PacketListEntry; a proper PacketList did not exist and all the related functions just passed pointers to pointers to the head and tail elements around. All these pointers were actually consecutive elements of their containing structs, i.e. the users already treated them as if they were a struct. So add a proper PacketList struct and rename the current PacketList to PacketListEntry; also make the functions use this structure instead of the pair of pointers.

* avdevice/decklink: remove pthread dependencyAaron Levinson2017-04-151-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
