Bug Description

In terms of both the Python packaging and Debian packaging, dmedia needs to be very modular because we need to deploy it across a wide range a scenarios. As a few examples:

 * media consumption apps (say Novacut player), have no intrinsic need for the dmedia importer or transcoder, so should be installable without

 * when running on a headless server, there is no need to install any graphical components and we might not want a DBus dependency

 * most of our artists are currently editing with Final Cut Pro, so running dmedia on OSX with with a Final Cut plugin would be a big win

So I'm proposing a component split something like this:

Python Packages:
  dmedia - core library, few dependencies outside Python standard library
  dmedia.service - DBus service stuff
  dmedia.webui - XML templates, JavaScript, CSS, and supporting Python
  dmedia.gtkui - GTK related stuff, like CouchView
  dmedia.importer - depends on gtkui, implements the Pro File Import UX
  dmedia.transcoder - transcode with GStreamer

(A lot of the above was already done during the 0.5 cycle.)

Debian Packages:
  python-dmedia - core Python library, no executables, minimal dependencies
  dmedia - bare bones DBus service, but with no tie to particular toolkit
  dmedia-webui - HTML5 UI components
  dmedia-gtkui - GTK integration
  dmedia-importer - dmedia-import script and everything else for file import
  dmedia-transcoder - GStreamer based transcoder
  dmedia-server - daemon for headless servers, started with upstart

Or something basically like that. Thoughts? Bilal, I'd love to work closely with you on this so it's done in a way that will work for the official Debain/Ubuntu packages... I think there's a huge advantage in having the daily builds and stable releases packaged exactly as dmedia is in the official packages

Bilal, when you have a chance, lets chat on #novacut about this... plus we'll see you at UDS-O :)

Bilal, as per our IRC conversation in #novacut, this is kinda what I'm thinking:

dmedia
    Virtual package
    Depends: dmedia-service || dmedia-server

dmedia-service
    Minimal DBus service, contains no UI elements itself
    Depends: python-dmedia, desktopcouch, python-dbus

dmedia-server
    System-wide headless server, started with Upstart
    Depends: python-dmedia, dmedia-webui, couchdb, python-gevent

python-dmedia
    Core Python lib, no executables
    Depends: python-couchdb, python-xgd

dmedia-webui
    Contains XML templates, JavaScript, CSS for dmedia HTML5 UI
    Depends: python-dmedia, python-genshi

dmedia-gtk
    Contains GTK widgets like CouchView, dmedia browser, etc
    Depends: dmedia-webui, python-gobject, gir1.2-gtk-2.0, gir1.2-webkit-1.0

dmedia-importer
    2nd DBus service, implement Pro File Import UX
    Depends: dmedia-service, dmedia-gtk, gir1.2-notify-0.7, gir1.2-appindicator-0.1

Why would -gtk depend on -webui? Is it necessary?

Jason Gerard DeRose (jderose) wrote :

Sorry, I lost your question in the noise for bit...

Yes, it is necessary because many UI components are HTML5, whether they run in embedded WebKit or not.

This is a decent explanation here:

This bug was fixed in the package dmedia - 0.6.0~repack-1

---------------
dmedia (0.6.0~repack-1) experimental; urgency=low

  * New upstream release.
  * debian/control:
    - Split up separate upstream components into separate Debian packages.
      (LP: #748016)
    - Change dependencies according to upstream changes.
    - Remove build-dep on libjs-mootools as mootools isn't used anymore.
    - Correct package synopsis by removing articles from them.
  * debian/*.install: Make appropriate changes for split up of separate
    DMedia components into individual binary packages.
  * debian/patches/02_fix_couchdb_deprecated_function.patch : Dropped,
    merged upstream.
  * debian/patches/01_fix_errors_in_manpage.patch: Refreshed to make patch
    apply properly in new upstream version.
  * debian/rules: Remove override_dh_installxfonts override as there's no
    need to link to mootools anymore

dmedia (0.3.0~repack-2) unstable; urgency=high

  * debian/control:
    - Remove dependencies on gir1.0-* and replace it with gir1.2-* as
      gir1.0-* packages no longer exist. (Closes: #622331)
    - Depend on desktopcouch directly as python-desktopcouch-records
      is now a virtual package.
    - Bump Standards-Version to 3.9.2 (no changes needed).

dmedia (0.3.0~repack-1) unstable; urgency=low

  * Initial release (Closes: #608364)
