Sortie d’OpenShot 2.4.2

Il s’agit d’un temps à rester au moins à l’ombre et pourquoi pas derrière son ordinateur (mais pas trop longtemps) Au menu de cette nouvelle version, des nouveautés, des corrections de bogues…. En avant la lecture….

Et comme d’habitude, la petite vidéo présentant toutes ces nouvelles fonctionnalités.

7 nouveau effets (Crop, Hue, Color Shift, Pixelate, Bars, Wave, Shift)

Chacun de ces effets a été crée de toutes pièces pour OpenShot. Bien entendu, ils fonctionnent pleinement avec les images clés et peuvent même être combinés ensemble. ils feront, d’ailleurs, probablement l’objet de tutoriels vidéos de la part de Jonathan.

Mixage audio automatique

Quand cette fonctionnalités est activé, les clips audios peuvent utiliser trois méthodes pour les cas où les clips se chevauchent et l’audio est en compétition à ce moment là. Par exemple, prenons le cas d’un arrière plan audio sur toute la durée de la vidéo. Arrive un moment où quelqu’un parle. L’audio d’arrière plan diminue automatiquement le volume pour laisser place à l’audio de la personne qui passe en premier plan. A préciser que cette fonctionnalité est désactivé par défaut. Rendez-vous dans les propriétés du clip pour l’activer.

Rotation automatique

Les photos et vidéos disposant de métadonnées de rotation seront automatiquement basculer. Attention, toutefois, cela dépendra de votre version de ffmpeg. Pratique avec les téléphones portables.

Amélioration de la lecture audio

La lecture audio et le mixage audio sont le point faible d’Openshot et font l’objet d’une attention et d’efforts particuliers. Beaucoup d’amélioration et de résolutions ont été réalisées

Amélioration de la stabilité

Chaque version d’OpenShot (et comme tout projet libre d’ailleurs) apporte son lot de correction de bogues. Le système Window semble plus visé que les autres, notamment à cause des dépendances mais pas que.

Amélioration  de la fenêtre d’exportation

Affichage de la progression de l’exportation avec affichage du nombre de fps et du temps estimé de l’encodage.

Nouveau codec audio

Le codec AAC est désormais le codec audio pour beaucoup de prèset afin d’obtenir une plus large compatibilité.

Migration du système de build

Utilisation de Gitlab et de GitFlow pour le développement. Tout ceci permet de mieux compartimenter le développement pour chaque branche, chaque commit,  Launchpad, Github, les versions (Linux, Mac, Windows x86, Windows x64), etc….

Personnellement je ne connaissais pas GitFlow ( ici et ici pour les curieux/ses).

Voici la liste complète des fonctionnalités et des commits réalisés par type de logiciels :

libopenshot-audio 0.1.6 so:6

• Fix under-linking (pthread and dl), fixes #3
• Integration of GitLab build pipelines

libopenshot 0.2.0 so:15

• Auto audio mixing strategy per clip (average, reduce, or none)
• Adding new crop effect, which can also be animated for some very cool effects.
• Adding new Color Shift effect, which can shift any color (RGBA) with infinite wrapping (and full supports animation).
• Adding new Pixelate video effect, which pixelates a portion (or all) of a frame’s image, and is fully animatable.
• Adding new video effect: Bars, which allow for animating colored bars around your video, such as a letterbox effect.
• Adding new wave video effect, which can be animated in a ton of ways to create lots of cool wave distortion effects.
• Adding Hue video effect, to adjust the hue of a frame’s image, which can also be animated with a keyframe
• Adding new effect: Shift, an infinite pixel shifting effect which can be animated and wrap images in any direction.
• Auto-Rotates any Clip with Reader metadata ‘rotate’ attribute.
• Experimental codecs now supported in FFmpeg/LibAV
• Audio popping during preview (due to resampling)
• Fixing brightness and Mask effects to calculate factor with a float type, giving more fine control
• Fix Blur.cpp by copying blur_<chan> values back to <chan> so horizontal *andvertical blurs can be applied in one effect and blur accumulates with increased iterations
• Update and apply frame mapper on any clip changes, to keep timeline offsets in sync (i.e. avoid audio popping due to slight misalignments of clips on the timeline).
• Removing old frames from WorkingCache (when no longer needed). This helps prevent freezing looking for old frame data on certain videos.
• Adding metadata from format, audio stream, and video streams to ReaderBase.info, which in some cases includes the ‘rotate’ metadata added by certain cameras, and audio metadata like title, album, artist, copyright, dates, etc…
• Added in metadata encoding capabilities (writer.info.metadata[« title »] = « My Title »). Only certain tag names are accepted (see FFmpeg for more on which tags are supported by which codecs).
• Optimize and improve speed of Mask effect (used by transitions). This is way faster than before!
• Fixing assignement and copy operators on Frame class (to prevent crashes for unintiailized image and audio pointers), and ensuring both copy and assignment operators work as expected.
• Fixing the color property of Frames, which was being lost on some constructors.
• Increase valid frame rates to 240 fps since many cameras now support this higher frame rate
• Fixing regression on Clip constructor, and simplifying pointer initialization
• Fixing a bug with Frame::AddImage (convertToFormat) not actually doing anything. It returns a new image, and does not convert the format in-place.
• Preventing crash if Seek invoked before QtPlayer are initialized properly
• FFMPEG 3.2 support for FFmpegWriter
• FFMPEG 3.2 support for FFmpegReader
• Fixing FFmpeg version breakage in FFmpegWriter
• Increasing the default amount of cache in FFmpeg, based on the # of processors, to better support high framerate videos.
• Changing some Seek values to be more accurate, and fixes a race condition with Timeline_Tests.cpp.
• Changing some sleep() calls to usleep(), for more accuracy. This is a bit experimental, and hopefully will work on all OSes.
• Do not clobber gainFactor when determining volume adjustments and add a TODO note about current_max_volume always being 0
• Removing anchor from clip properties (since it is unused)
• Adding « dbghelp » dependency for Windows builds (for crash handling support), and improved Windows build instructions using MSYS2.
• Properly set test media files path, fixes #36
• Fixing black frames at end of video clips, if audio stream longer than video stream, and end-of-stream is reached.
• Integration of GitLab build pipelines
• Faster Windows builds
• Fixing audio unit tests
• Avoid mixing audio for clips with no volume or disabled audio.
• Updating cmake file for libopenshot-audio to search $ENV first, and then static folders
• Add missing type cast
• Spelling and typo fixes

openshot-qt 2.4.2

• More detailed export dialog progress, including estimate time remaining, FPS, and more accurate percentage. Thanks Peter!
• Defaulting to AAC audio codec
• Improving zoom scale calculation, to use a custom bezier curve (zoom gets faster and faster the more you zoom out). 30 levels of precision between 1 second and 7200 seconds.
• Auto-rotate for Readers with ‘rotate’ metadata. This requires a slightly newer version of FFmpeg, otherwise the ‘rotate’ tag is never found.
• Adding new Crop video effect
• Adding new Color Shift video effect (with temp icon)
• Adding Pixelate video effect, which can animate a pixelated version of part (of all) of a video clip.
• Adding new Bars video effect, which allow for animating colored bars around your video, such as a letterbox effect.
• Adding new Wave video effect
• Adding Hue video effect
• Adding new Shift effect (which allows for shifting the image in any direction and allows for animation, with infinite wrapping)
• Support for 32-bit and 64-bit Windows builds, and an update to the Windows dependencies (and installer size reduction).
• 32-bit version of Windows is now large address aware, and can make use of more memory, but users might need to run this command first: ‘bcdedit /set IncreaseUserVa 3072’ in order to utilize this
• No longer crash app if user settings cannot be read. Now we show a message box and reset the user settings.
• Adding save indicator in window title
• Retain track parameters during add/remove track
• Update titles to be compatible with newer versions of Inkscape
• Always apply mapper when opening a project, to ensure no audio starts popping for different framerate projects
• Split Clip dialog now sends focus back to slider after clicking ‘Start’ or ‘End’ or ‘Play’ (to make it easier for frame-by-frame arrow keys)
• Make clip and transition menus trigger on mouse-down, and not move the timeline item when the menu is activate
• Removing max constrains from export length, so user can export blackness at the end of his project if so desired.
• Disabling/Enabling save icon based on if the project needs saving
• Add preset xml file for chromebook target
• Removing unneeded 64-bit/32-bit clean-up code from Windows installer (which breaks on a 32-bit system)
• Fix initial save indicator on a new (blank) project
• Also use import_path for missing-file recovery
• Add import_path tracking to project data
• Updating mac build scripts to use Python 3.6 (with a newer version of OpenSSL)
• Preview controls use media-skip icons
• New razor-tool cursor
• Adding new developer page to documentation, with step by step instructions on getting a Ubuntu development environment setup for libopenshot, libopenshot-audio, and openshot-qt.
• Position is always (frame – 1) / fps
• Utility functions for unit conversion
• Be more explicit about logfile paths
• Adding back in /usr/lib/x86_64-linux-gnu/libfontconfig.so.1 to the AppImage
• Rename dv_pal_wide_animorphic to correct spelling
• Remove duplicate profiles
• Protect slack upload better during build server
• Updating sponsors, donors, and contributors
• Updating translations
• Change the if statement for default language to use system default
• Copy log file for each successful build (for debugging reasons)
• Use QUrl.toLocalFile() to convert dropped URIs
• Add Contributing section
• Update Tutorial, Code tags and contrib link
• Update GitHub info in tutorial
• Use images/ path for images, not _static/ in documentation
• Fix wrapping in Tutorial documentation
• Replace ASCII arrows with Unicode arrow character in documentation
• Also update transition layer on track add/remove
• Small refactor of build server file uploads, and added extra check for ‘already uploaded’ assets to GitHub
• Improve error message for failed uploads during build server
• Remove torrents if already existing
• Integration of GitLab build pipelines
• Updating font family on built-in titles
• Remove some unneeded copies of libopenshot and libopenshot-audio in the AppImage, reducing size of AppImage
• Fixing issue with Linux AppImage creation on build server
• Migrating from Bzr to Git (on Launchpad)
• Delete old ISSUE_TEMPLATE
• Correct a cut-and-paste wrong comment
• Fixing copyright to use translation-friendly formatting, and hiding hardware decode preference (for now)
• Update websites section and removal of too many caps
• Change readme to be markdown
• Log length of metrics response, not content
• Updated copyrights to 2018 (from 2016). Also edited `about.py` so the year is automatically updated.
• Adding a few missing dependencies into the developer doc page
• .gitignore: ignore docs/_build & all pycache

Git Changes

• Implementing GitFlow for project (develop, release, and master branches)
• Protected branches (on all repos), preventing direct pushes
• Must pass unit tests and status checks before merges allowed
• Must go through the Pull/Merge Request flow to be merged into a protected branch
• Automated git repo syncing between GitHub->GitLab->Launchpad
• Automated GitLab CI build pipelines (all builds, tests, installers, daily installers, are run through GitLab CI now)
• Builds and installers also support any branch, making feature branches and test branches much more useful, since we can share installers for them
