Hallo all,
i currently work on project for extracting and interpreting information provided by digital cameras. Suddenly there is no match methadata provided in video or audio files. Current gstreamer can't read any of it. Please take look at this list with different dumps, if you have some time pleas add this RIFF tags, if don't i will do it at sumer. http://docs.google.com/View?id=d57752n_32f7pb3kdm To extract more information we (tracker) will need to interpret directory tree: http://docs.google.com/View?id=d57752n_27ddtp6qzj Regards, Alexey ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.

Imho thats outside of the riff-wav specs (same for avi). There are plans for writing internal exif support for gstreamer. If it could be used here too (outside of jpeg) it would be good to account for that. I wonder if you can find some sources that document these file format extensions.

Do you plan to support all EXIF tags? Or it make more sense to use some independent library? Current gstreamer can't extract metadata on any files produced by digital cameras, exaftool can. It handle even ogg, mov, avi, many image formats ... But it can't handle mkv files. What longterm solution is better for example for tracker, to add mkv to exiftool or to add exif to gstreamer? http://www.sno.phy.queensu.ca/~phil/exiftool/ ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.

The plan is to have exif support for jpegformat plugin too, but now I would think it is better to have exif support in gst-plugin-base the same way we added xmp there. I simply did not know that it is used anywhere else then jpeg. > Current gstreamer can't extract metadata on any files produced by > digital cameras, exaftool can.
