Please post the exact packaging diagnostic messages.

We can't remove the build time dependency, as it is really needed.

If the binary packages generated still somehow have a dependency on
ffmpeg-xpra (or was it the .so libraries themselves?), we may need to
either add more dh_shlibdeps overrides or split the codecs into their
own package.

Not sure I'll have much to investigate either option in the near future,
but you can easily do this yourself by following:
http://xpra.org/trac/wiki/Building/Debian
(some tweaking may be required)

Cheers
Antoine

Unfortunately changeset 17145 was not included in the latest available xpra 2.2 beta which is from yesterday morning. Could you trigger a new xpra 2.2 beta build for centos including that changeset?

The Packages file for debian stretch amd64 is currently empty (see https://xpra.org/beta/stretch/main/binary-amd64/ ) and I can’t install from the repository anymore. Can you have a look?
