* avfilter: add QSV variants of the stack filtersHaihao Xiang2023-02-16
| | | | | | | | | | | | | | | | | | | Include hstack_qsv, vstack_qsv and xstack_qsv. They may accept input streams with different sizes. Examples: $ ffmpeg -hwaccel qsv -hwaccel_output_format qsv -i input.mp4 \ -filter_complex "[0:v][0:v]hstack_qsv" -f null - $ ffmpeg \ -hwaccel qsv -hwaccel_output_format qsv -i input.mp4 \ -hwaccel qsv -hwaccel_output_format qsv -i input.mp4 \ -hwaccel qsv -hwaccel_output_format qsv -i input.mp4 \ -hwaccel qsv -hwaccel_output_format qsv -i input.mp4 \ -filter_complex "[0:v][1:v][2:v][3:v]xstack_qsv=inputs=4:fill=0x000000:layout=0_0_1920x1080|w0_0_1920x1080|0_h0_1920x1080|w0_h0_1920x1080" \ -f null - Signed-off-by: Haihao Xiang <haihao.xiang@intel.com>

* avformat/movenc: allow writing out channel count in MP4 and 3GPJan Ekström2023-02-14
| | | | | | | | | | | | | | | | | | | ISOBMFF (14496-12) made this field ('channelcount') in the AudioSampleEntry structure non-template¹ somewhere before the release of the 2022 edition. As for ETSI TS 126 244 AKA 3GPP file format (V16.1.0, 2020-10), it does not seem contain any references limiting the channelcount entry in AudioSampleEntry or in its own definition of EVSSampleEntry. fate-mov-mp4-chapters test had to be adjusted as it output a mono vorbis stream, which would now be properly marked as such in the container. 1: As per 14496-12: Fields shown as “template” in the box descriptions are fields which are coded with a default value unless a derived specification defines their use and permits writers to use other values than the default.

| | | | | | | | | | | | | When building FFMPEG in the MSYS environment under Windows, one must not use forward slashes ('/') for command-line options. It appears that the MSYS shell interprets these as absolute paths and then automatically rewrites them into equivalent Windows paths. For example, the '/nologo' switch below gets rewritten to something like 'C:/Program Files/Git/nologo', and this obviously breaks the build. Thankfully, most M$ tools accept dashes ('-') as well.

* 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.
* lavfi/avfilter: track whether a filter has been initializedAnton Khirnov2023-02-12
| | | | Refuse to link uninitialized filters or initialize a filter twice.
* lavfi/avfilter: export process_options()Anton Khirnov2023-02-12
| | | | | | | Also, replace an AVFilterContext argument with a logging context+private class, as those are the only things needed in this function. Will be useful in future commits.
