Modifying and writing tags

[David Ó Laigheanáin]

Hi,

I am currently tying to modify tags and write them back to the original
file. I can get the TagList with DiscovererInfo, but I'm unsure of how
to save these changes. Is it even possible with gstreamer?

Any help would be appreciated.

Thanks,
David

Our tag editing story is not great, there's no automatic handling for
this case yet. It should be possible for all common formats, but you'll
probably have to construct pipelines on a per-tag/format basis
yourself. Rhythmbox might have some code you could look at.

Its is not as straight forward as discovering them. To write tags you
need to remux the files and send the changed tags. Take a look at
encodebin (which can be used for transmuxing too).
