Andreas Rheinhardt	497a0f839d	avformat/img2: Avoid relocations for ff_img_tags The strings here are so short that using a pointer is wasteful (the longest string takes nine bytes; on 64 bit systems, the pointer+padding already take 12 bytes). So avoid them and add asserts to ensure that no one ever tries to use a too long tag. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	9 months ago
Alexandre Heitor Schmidt	ae436cc5e4	avformat/img2dec: add option to provide metadata fields related to input path 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.

Michael Niedermayer	7ccedc1c78	avformat/img2dec: do not interpret the filename by default if a IO context has been opened With this, user applications which use custom IO and have set a IO context will not have their already opened IO context ignored and glob/seq being interpreted Comments and tests from maintainers of user apps are welcome!
