metadata and multifilesink problem

Kaj-Michael Lang
Hi

I'm trying to basically do (in C) a pipeline like this:
v4l2src ! jpegenc ! metadatamux ! multifilesink

with an event handler for the jpegenc "frame-encoded" signal setting
tags for the frame. But tags get saved in the first jpg saved by
multifilesink only.

Am I doing something wrong or is it a bug in metadatamux, multifilesink
or can't it just be done? Any ideas on a workaround? I've tried with
both a GstTagSetter and sending a tag event.

probably a bug in the metadatamux. I am currently work on replacemanets for
metadata plugin. gst-plugin-bad has a new element jifmux (jpeg interchange
format muxer). The version in git writes GST_TAG_COMMENT to the jpeg comment
field. Can you try that element instead of metadatamux to see if it suffers from
the same problem?

The "jifmux" elements works, every jpg file gets the comment field set
properly.
