* avformat: deprecate AVFormatContext io_close callbackMarton Balint2023-02-16
| | | | | | io_close2 should be used instead. Signed-off-by: Marton Balint <cus@passwd.hu>
* avutil/frame: deprecate AVFrame.coded_picture_number and display_picture_numberMarton Balint2023-02-13
| | | | | | | | Their usefulness is questionable, very few decoders set them, and their type should have been int64_t. A replacement field can be added later if a valid use case is found. Signed-off-by: Marton Balint <cus@passwd.hu>
* avcodec: add AVCodecContext.frame_num as 64 bit variant to frame_numberMarton Balint2023-02-13
| | | | | | | | | | Frame counters can overflow relatively easily (INT_MAX number of frames is slightly more than 1 year for 60 fps content), so make sure we use 64 bit values for them. Also deprecate the old 32 bit frame_number attribute. Signed-off-by: Marton Balint <cus@passwd.hu>
* fftools/ffmpeg: add special syntax for loading filter options from filesAnton Khirnov2023-02-12
| | | | | | | | | | | | | | | | | Many filters accept user-provided data that is cumbersome to provide as text strings - e.g. binary files or very long text. For that reason such filters typically provide a option whose value is the path from which the filter loads the actual data. However, filters doing their own IO internally is a layering violation that the callers may not expect, and is thus best avoided. With the recently introduced graph segment parsing API, loading option values from files can now be handled by the caller. This commit makes use of the new API in ffmpeg CLI. Any option name in the filtergraph syntax can now be prefixed with a slash '/'. This will cause ffmpeg to interpret the value as the path to load the actual value from.
* lavfi: add a new filtergraph parsing APIAnton Khirnov2023-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Callers currently have two ways of adding filters to a graph - they can either - create, initialize, and link them manually - use one of the avfilter_graph_parse*() functions, which take a (typically end-user-written) string, split it into individual filter definitions+options, then create filters, apply options, initialize filters, and finally link them - all based on information from this string. A major problem with the second approach is that it performs many actions as a single atomic unit, leaving the caller no space to intervene in between. Such intervention would be useful e.g. to - modify filter options; - supply hardware device contexts; both of which typically must be done before the filter is initialized. Callers who need such intervention are then forced to invent their own filtergraph parsing, which is clearly suboptimal. This commit aims to address this problem by adding a new modular filtergraph parsing API. It adds a new avfilter_graph_segment_parse() function to parse a string filtergraph description into an intermediate tree-like representation (AVFilterGraphSegment and its children). This intermediate form may then be applied step by step using further new avfilter_graph_segment*() functions, with user intervention possible between each step.

* avutil/{color_utils, csp}: merge color_utils into csp and expose APILeo Izen2023-02-09
| | | | | | | | | | | | | | | | | | | | | | | | libavutil/color_utils contains some avpriv_ symbols that map enum AVTransferCharacteristic values to gamma-curve approximations and to the actual transfer functions to invert them (i.e. -> linear). There's two issues with this: (1) avpriv is evil and should be avoided whenever possible (2) libavutil/csp.h exposes a public API for handling color that already handles primaries and matricies I don't see any reason this API has to be private, so this commit takes the functionality from avutil/color_utils and merges it into avutil/csp with an exposed av_ API rather than the previous avpriv_ API. Every reference to the previous API has been updated to point to the new one. color_utils.h has been deleted as well. This should not break any applications as it only contained avpriv_ symbols in the first place, so nothing in that header could be referenced by other applications.

* fftools/ffmpeg: add an option for writing pre-muxing statsAnton Khirnov2023-02-09
| | | | | | Analogous to -enc_stats*, but happens right before muxing. Useful because bitstream filters and the sync queue can modify packets after encoding and before muxing. Also has access to the muxing timebase.
* avformat/hls: Add option to retry failed segments for hlsgnattu2023-02-09
| | | | | | | | | | | Current HLS implementation simply skip a failed segment to catch up the stream, but this is not optimal for some use cases like livestream recording.

* ffmpeg: add video heartbeat capability to fix_sub_durationJan Ekström2023-02-03
| | | | | | | | | | | | | | | | | | | Splits the currently handled subtitle at random access point packets that can be configured to follow a specific output stream. Currently only subtitle streams which are directly mapped into the same output in which the heartbeat stream resides are affected. This way the subtitle - which is known to be shown at this time can be split and passed to muxer before its full duration is yet known. This is also a drawback, as this essentially outputs multiple subtitles from a single input subtitle that continues over multiple random access points. Thus this feature should not be utilized in cases where subtitle output latency does not matter.
