How to pass SMPTE KLV metadata in a pipeline

[Josh Doe]

I'm interested in what might be the best way to pass SMPTE KLV
(http://en.wikipedia.org/wiki/KLV) metadata in GStreamer. There are
already several elements that could be producing/consuming KLV data
(mxfmux, mxfdemux, mpegtsmux, mpegtsdemux). It would be nice to have a
standard way of communicating this data, so these and other elements
can interoperate. Perhaps KLV packets can be sent as their own stream,
or as events? Anyone else interested in this?

Hi Josh,

As you know, I posted a similar question in July this year. Since then 3
or 4 people have contacted me off-list asking if I got anywhere. There
appears to be an interest in the ability read and write KLV.

Hi Josh and Paul,

there's definitely some interest in this and part of this (the KLV
parsing/generating) is already implemented in the MXF plugin. This only
has to be improved and get better interfaces.
