hello, I would like to know if it possible to read jpeg EXIF data using libavformat/libavcodec.
I can see there is an exif tag list in ffmpeg sources, but I don't know how to access to it. Using "metadata.c" example in doxygen, I can't read anything. AVFormatContext->metadata is null. Note that jpg file has exif data because I can read it with exiftool. Can someone please point me to some doc/examples? thanks, MB
