Hi there! I'm just writing to make sure this patch wasn't forgotten. :)

The patch follows attached, to avoid formatting issues. The commit message is as follows: avformat/image2: Upon request, make available extra metadata fields related to input path to be used by filters. 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.
