0.91 Release "Charming Defects"
This is the first alpha release for the new version of Pitivi based on GES, the GStreamer Editing Services library.
It is a major rework of the entire Pitivi architecture. It includes:
- Replacing the core of Pitivi by GES; 20 thousand lines of code removed
- Porting to GStreamer 1.x
- Porting to GTK+ 3.x
- Replacing GooCanvas by Clutter for the timeline
- An automated UI test suite, with many checks for mission-critical parts
- Fixing hundreds of bugs and implementing many new features
- UI polish all over the place
- Refactoring pretty much the entire codebase
To give you a visual idea of what this meant:
WARNING: Please keep in mind that this is an alpha release, so there may be some bugs we haven't found yet. We appreciate your feedback, so try it out, let us know how well it works for you and report detailed bugs for issues you may encounter. Again, this is not yet considered production-ready software. We can't be sure until we test and iron out the bugs! With your help, we will follow up with a beta release and eventually a 1.0 release.
Top features of this release
These features have been documented throughout many blog posts from January 2012 to September 2013. Take a look at the "Pitivi" category of Jeff's blog for additional details and historical context.
- The redesigned clip previewing feature gives you more space to view a video from the media library, yet stays out of your way. It now opens a separate window that tries to show the clip at 1:1 size whenever possible. This window can be dismissed by clicking the close button or clicking anywhere outside the window, so there is no reduction of efficiency compared to the old approach.
- Use Nautilus/Totem’s thumbnails and conform to the new version of the Freedesktop specification for thumbnail directories. The result is prettier and we don’t have to do processing in most cases, which means even faster import/loading times.
- Asynchroneous (non-blocking) and much faster clip importing
- The media library keeps itself sorted alphabetically as you import files, without any additional performance hit.
- Prevent playing back clip previews in double (that was a subtle one, as windows were exactly on top of each other)
- Make special characters show up correctly in the media library’s iconview mode, remove the ancient filename shortening code and rely on Pango instead.
- Avoid excessive work when searching clips in the media library, improving performance
- Handle special characters in the media library’s search entry
- Use the system’s default image viewer to preview images
Timeline and Playback
- Smooth, modern Clutter-based timeline with animations to enhance usability
- Smooth autoscrolling while playing
- Live preview of what you are trimming. No more trial and error, no more fuzzying around and moving the playhead all the time to figure out if you cut your scene right.
- Playback performance back to the 0.13.1 levels (or possibly better). Want to play a 1080p clip? A 2K clip? Not a problem anymore (unless you're still running on a 286 or something).
- Much faster and prettier video thumbnails on the timeline, with two-stage caching and adaptive CPU usage throttling
- Much faster and more accurate audio waveforms, with on-disk caching
- Manual layers management interface, layer reordering
- The timeline toolbar is now vertical and sports improved “Split”, “Group” and “Ungroup” icons. It also does away with obsolete buttons.
- Automatic rippling (a.k.a. "magnetic", elastic, fantastic) timeline mode: this makes your clips behave like magnets and prevents needing to re-arrange them manually all the time.
- Automatically adjust the zoom when inserting to the end of the timeline
- New icons for split, group/ungroup and align
- Clip snapping indicator
For contributors and distributors
- Infinitely cleaner and easier to navigate codebase. See this blog post and this blog post for an explanation and some numbers, or just look at this screenshot comparing the old and new amount of source files.
- An awesome test suite
- A revised and simplified API has been implemented in GES and integrated in Pitivi.
- A small brand adjustment. From now on, PiTiVi should simply be called "Pitivi".
- Dependencies are defined and checked in only one, centralized place: check.py
- We now use yelp-tools instead of gnome-doc-utils
- New format for which a mimetype needs to be registered: xges
- Commandline rendering, scripting and batch processing is now GES' job
- New high-resolution logo icon
- Various pieces of documentation (README, HACKING, AUTHORS, etc.) were updated
- We ship an AppData file in order to show up with the correct description in GNOME Software
- We dropped the ChangeLog file, it weighs a ton and we have this thing called version control systems now.
- In addition to the good old "crossfade", you can now choose from 70 industry-standard (SMPTE) transitions. This number doubles to 140 if you consider that each transition can also be reversed.
- Pitivi now inhibits the screensaver when playing and inhibits suspend when rendering.
- The automated backup feature now works. See this blog post and its sequel
- Simplified menus
- Fix many, many, many problems with the Media Library, project management, keyboard shortcuts, etc.
- Ability to save/export the current frame as an image file
- Much faster application startup
- Auto-hiding toolbar in fullscreen mode
- Improved error dialogs
- Automatically saving and restoring the state of our dynamic detachable tabs/components.
- Redesigned rendering progress dialog and post-render user experience. See this, this and this.
- Enforce unicode in preset names, preventing a bug with non-ASCII chars are used in the name of a preset
- Allow presets with “/” in their name
- Fix a race between clicks on the preview widget’s slider and position updates. When using it in the media library/file chooser, the slider would often “jump” back to its previous position instead of seeking. The new behavior is now smooth and reliable.
- When the viewer is undocked, provide a button to toggle fullscreen mode
- Specify the duration of missing/moved files when prompting the user about their new location
- Update effect categories, merge “Noise” and “Blur”, add a “Compositing” category, categorize new effects
- Automatically save the last used render directory
- Stop rendering when the user presses Escape
- Use symbolic icons everywhere where it makes sense (in the media library toolbar, property reset buttons, lists, etc.)
- Update the preview widget slider on a more frequent basis, giving it a snappier feeling
- Automatically save and restore the main window’s position. This is especially useful when using detached utility windows.
- Hide the effects toolbar when nothing is selected
- Add a contextual help button in the render dialog to explain container formats
- Allow entering a frame number into the time widget
- Keyframable (animatable) properties for all effects
- Scale down effects thumbnails to fit better in the new listview arrangement
- Various improvements to the robustness of the import dialog's video previewer
- Ability to pause and resume rendering
- A basic title editor
- Filter the project loading or media file importing dialogs to only show relevant/supported files by default
- Only show codecs and containers with a high-enough GStreamer "rank" to reduce the possibility of rendering problems
This is just the beginning, of course. See the "Bugs fixed (and even more features)" section further below if you're hungry for more.
Dependencies/requirements have changed significantly since the 0.15 series.
Generally speaking, you can refer to Pitivi's check.py for the dependencies' versions specific to a given release. For 0.91, those are:
- cairo >= 1.10.0
- clutter >= 1.12.0
- gnonlin >= 1.1.90
- gobject-introspection >= 1.34.0
- gst-python >= 1.1.90
- gstreamer >= 1.2.0
- gstreamer-editing-services >= 1.1.90
- gtk >= 3.8.0
- numpy (static bindings)
- pygobject >= 3.4.0
- pyxdg (static bindings)
- pycanberra (static bindings)
See also dependencies for additional tips.
- Layer management interface is missing features.
- The title editor UI is very primitive and probably buggy. Please join us to make it work up to your expectations! See the existing title editor bugs.
- The transformation box has been disabled (we need someone to fix it).
- The user manual is completely outdated (it references the 0.15 series). We are looking for someone to take on the role of writing the Pitivi user guide. Please get in touch if you love writing and are interested in helping out.
- Translations are not all fully up to date.
- The Media Library does not generate missing thumbnails. See GStreamer bug 667203 for details.
- The ruler has not been ported to Clutter, so it will not be in sync with the rest of the timeline while autoscrolling.
- The automated codecs installer is (still) broken. See bug 686182 and GES bug 686181.
- The automatic clip aligner feature does not work. We need someone to port it to use our new audio waveforms processing module.
- If xptv file support is important to you, we urgently need someone to get involved in fixing/refactoring the xptv formatter module in GES. If no interest is shown after a few releases, support for this legacy file format may be dropped.
- No dialog to install missing codecs after discovering clips, and no error gets raised in that case. This means that the clip will "appear" to have imported correctly, but if you try inserting it into the timeline you may get errors in the background or Pitivi's UI may hang.
Bugs fixed (and even more features)
It is difficult to evaluate the amount of commits directly related to Pitivi in GStreamer. However:
- At least 50 bugs in GStreamer have been fixed by Mathieu Duponchelle between January and September 2013:
- At least 96 bugs in GStreamer since 0.15 mention Pitivi
In GStreamer Editing Services, the Pitivi team has made 975 commits in preparation for this release.
- Hundreds of bug reports were resolved
- There were 1348 commits between 0.15.2 and 0.91.
Since you're reading the release notes of an an alpha release, we suspect you might be pretty geeky, so here are roughly 150 (of the 1300+ commits) that are "interesting" but were not necessarily big enough to be mentioned in the "top features" above.
