* avcodec/vbndec: add VBN decoderMarton Balint2022-04-10
| | | | | | | | Add support for decoding Vizrt Binary Image (VBN) files. LZW-compressed data is not supported yet. Signed-off-by: Marton Balint <cus@passwd.hu>
* configure: Use a separate config_components.h header for $ALL_COMPONENTSMartin Storsjö2022-03-16
| | | | | | | | This avoids unnecessary rebuilds of most source files if only the list of enabled components has changed, but not the other properties of the build, set in config.h. Signed-off-by: Martin Storsjö <martin@martin.st>

* avformat/img2dec: probe JFIF/Exif headerAlex Xu (Hello71)2021-11-27
| | | | | | | | | | | | | | | | | Due to reasons, mpv doesn't pass filename when probing. mpv also sets default probescore threshold to 26. Since the current jpeg_probe implementation returns 25 until EOI, it means that the whole image needs to be probed to succeed. Worse, the whole image is not passed at once; increasingly large buffers are tried before that. Adding it up together, if many demuxers are enabled, moderately large JPEG files (few MB) can take several seconds to open, despite taking less than 1 second to actually decode. Therefore, adjust the heuristic to be more optimistic if proper JFIF or Exif segments are found. While not strictly required, the vast majority of JPEG-ish files have one or the other or both.

* avformat: Avoid allocation for AVStreamInternalAndreas Rheinhardt2021-09-17
| | | | | | | | | | Do this by allocating AVStream together with the data that is currently in AVStreamInternal; or rather: Put AVStream at the beginning of a new structure called FFStream (which encompasses more than just the internal fields and is a proper context in its own right, hence the name) and remove AVStreamInternal altogether.

* avformat/img2dec: Deduplicate AVClassesAndreas Rheinhardt2021-07-08
| | | | | | | | The child_class_next API relied on different (de)muxers to use different AVClasses; yet this API has been replaced by child_class_iterate. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat/img2dec: set r_frame_rate in addition to avg_frame_rateJan Ekström2021-04-11
| | | | | | | | | Apparently for various image sequences libavformat/utils.c can calculate rather fancy r_frame_rate values, such as `186/1921`, and since ffmpeg.c utilizes r_frame_rate for the filter chain time base, this can quite deteriorate the output frame timing - even though the user has requested the image sequence to be interpreted at a specific, constant frame rate.
* avcodec/packet: Also change av_packet_pack/unpack_dictionary to size_tAndreas Rheinhardt2021-03-19
| | | | | | | | | These are auxiliary side-data functions, so they should have been switched to size_t in d79e0fe65c51491f9bf8a470bbe36fb09f3e1280, but this has been forgotten. Reviewed-by: James Almer <jamrial@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* lavf: move AVStream.*index_entries* to AVStreamInternalAnton Khirnov2020-10-28
| | | | | | | Those are private fields, no reason to have them exposed in a public header. Since there are some (semi-)public fields located after these, even though this section is supposed to be private, keep some dummy padding there until the next major bump to preserve ABI compatibility.

* avformat: Remove unnecessary av_packet_unref()Andreas Rheinhardt2020-02-10
| | | | | | | | | Since bae8844e the packet will always be unreferenced when a demuxer returns an error, so that a lot of calls to av_packet_unref() in lots of demuxers are now redundant and can be removed.

* avformat/img2dec: add option to provide metadata fields related to input pathAlexandre Heitor Schmidt2020-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libavformat/img2.h: New field export_path_metadata to VideoDemuxData to only allow the use of the extra metadata upon explicit user request, for security reasons. libavformat/img2dec.c: Modify image2 demuxer to make available two special metadata entries called lavf.image2dec.source_path and lavf.image2dec.source_basename, which represents, respectively, the complete path to the source image for the current frame and the basename i.e. the file name related to the current frame. These can then be used by filters like drawtext and others. The metadata fields will only be available when explicitly enabled with image2 option -export_path_metadata 1. doc/demuxers.texi: Documented the new metadata fields available for image2 and how to use them. doc/filters.texi: Added an example on how to use the new metadata fields with drawtext filter, in order to plot the input file path to each output frame. Usage example: ffmpeg -f image2 -export_path_metadata 1 -pattern_type glob -framerate 18 -i '/path/to/input/files/*.jpg' -filter_complex drawtext="fontsize=40:fontcolor=white: fontfile=FreeSans.ttf:borderw=2:bordercolor=black: text='%{metadata\:lavf.image2dec.source_basename\:NA}':x=5:y=50" output.avi Fixes #2874.
